Boise River Update

This year marked some really exciting advances for our Boise River Project, with big strides forward for the site development, outreach, and research aspects of the project, including plans for a capital campaign!

Development

IBO has worked over the past 5 years to secure more than 20 acres of property along the Boise River along Warm Springs Avenue in southeast Boise.  First, in 2012, Boise State worked closely with Idaho Transportation Department to secure management of a parcel of river bottom at the Highway 21 bridge site.  A few years later, the university purchased an adjoining parcel of riverfront using annual interest accrued on IBO’s Diane and Winston Moore Family Endowment.  The power of this lasting gift continues to benefit IBO in the most significant ways!

A Master Plan

We have used the property over the past few years to develop an outreach and education program headed by our Education Director, Heidi Ware.  Recently we have created a conceptual master plan for this area to enhance its natural features and to develop infrastructure that will aid in our outreach activities in the future.  

Boise River Site Master PlanThe plan includes restoring a natural side channel of the river to improve fish and wildlife habitat, developing an interpretive trail system, spanning wetlands with raised boardwalks to protect critical habitat, constructing wildlife viewing blinds, restoring upland habitats, and creating pollinator gardens on the properties.

We have identified multiple funding opportunities and have submitted applications to the U.S. Army Corp of Engineers for restoration of the side channel and other habitat improvements.  We have also submitted an application to Boise City under their Open Space and Clean Water Partnership Program for development of interpretive trails and boardwalks.  

Planning for the Future

We plan to initiate a fundraising campaign working closely with the Boise State development team to create a programing endowment of $1.5 M that would support our educational efforts at the site in perpetuity.  

We will need your help to do all of this!

A City Park

A new and exciting twist which has surfaced recently are plans to develop a Boise City park on the adjoining property located along Warm Springs Avenue.  Aaron Howell, a private individual, has purchased this property and plans to develop the park and donate it to the city, naming it after his wife Sue.   The park will have facilities to accommodate exercise as well as provide Greenbelt access, but will also have a science-based theme.  We are very excited to work with Mr. Howell and the city to create a park theme and park amenities that will promote access to and use of IBO’s properties.  

We believe that linking management of a city park and an adjoining natural area will create a valuable and long-lasting legacy for residents of the City of Boise.  We plan to cooperate with Mr. Howell and the city to ensure that the park has features that can be shared with Boise State such as bus accessible parking facilities, covered meeting space that can be used for outreach, and trails joining the two properties.  This new twist has breathed new life into this age-old dream of IBO’s of having a local, accessible, natural property for year-round education and outreach!

Building Partnerships

We are happy about new (and old) partners that have surfaced to lend support for this project, such as the U.S. Army corps of Engineers, Boise City, The Boise River Enhancement Network, Idaho Rivers United, College of Western Idaho, and of course, our long-time partner Golden Eagle Audubon Society.  The Land Group, headed by Dave Koga, generously created the concept plan, and a new friendship with the Boise State Construction Management group will ensure quality and economical construction of new amenities on the property.

education shelter

Thanks to generous sponsors, we were able to purchase a shipping container to serve as an education shelter on the site. Thank you to Golden Eagle Audubon Society, Wild Birds Unlimited of Boise, Madeline George Garden Design and Nursery, Barbara Howard, Anthony Hill, and Matthew, Jennifer, & Derek Miller. We have plans to add a community mural to the walls of our shelter in 2018.

In 2017 we reached more visitors than ever! We hosted seven springtime field trips to watch birds, test Boise River water quality, and study mammals on our array of trail cameras.

Over the summer, we saw more than 300 of you at our MAPS banding sessions.

And this fall we reached more than 600 visitors at our daily autumn migration banding! We held field trips for more than 15 different Treasure Valley schools, hosted limited-mobility visitors (thanks to the easy access the site provides), and Heather organized our first Veterans field trip.

To top off a great fall season, we held our first “benefit for the birds” at the river! Be sure to check out Heather’s update to hear how our Waffles and Warblers event went!

Research

Summer

2017 marked our 3rd year of breeding season banding on the Boise River. The “Monitoring Avian Productivity and Survivorship” protocol is an important continent-wide monitoring effort that the Institute for Bird Populations coordinates. With both Lucky Peak and the Boise River serving as sites for this project, we acquired some great data about what is happening in our region with breeding birds.

If you’re a birder and want to see a Yellow Warbler in July or August, we can safely promise you that you’ll see them if you visit our Boise River site. We banded hundreds of Yellow Warblers on the river this summer, including some of the fattest Yellow Warblers we’ve ever seen. Normally a Yellow Warbler weighs about 9 grams, but the birds in August were so fat that they weighed in at 13 grams!

Although probably one of the most widespread species in North America, Yellow Warbler populations have been slowly declining across the continent. Monitoring projects like ours are collecting valuable information about their population trends and what habitats they rely on most. The habitat at our Boise River site seems to be ideal to support a very healthy Yellow Warbler population during post-breeding dispersal and migration.

Fall

2017 was our FIRST EVER fall migration season along the river. Although we didn’t have much money in the bank, we took the chance and hired technicians for a fall migration project. We banded daily (except in bad weather) from September 1st to October 20th. In the end, we collected data on more than 1,000 birds of nearly 30 species that migrated through the Boise River site. This gave us the best picture yet of what happens at the Boise River during migration and what kind of stopover habitat it provides for birds.

It cost us $4,000 to run our station for 2 months in 2017. We have about $1,000 in our budget for 2018 so far, thanks to our Waffles and Warblers event.

Follow this link and support our efforts in 2018 by selecting our Outreach Program in the designation.

Thanks to a grant from the Idaho STEM Action Center we were also able to deploy trail cameras on site. These cameras provided great fodder for student inquiry about mammals, humans, and how they co-exist in the wildland-urban interface on the Boise River. Here are a few of our favorite photos from the site:

The IBO team is growing!

IBO continues to expand its staff as a result of expanding support and capacity. Thanks to efforts of our Research Director Jay Carlisle and IBO staff biologists Robert Miller and Jessica Pollock, IBO’s research budget grew again in 2017. We currently have ~$1M in grant funding spread over ~25 different projects. Wow!  

 

This increased support required that IBO again expand its ranks in 2017, hiring Jeremy Halka (past IBO Curlew field team and Lucky Peak Trainee) and Tempe Regan (graduating Boise State MS student and past IBO International Intern who worked in Spain).

These two worked jointly to manage IBO’s IMBCR (grid-based point counts) projects within the Intermountain West, but also lent their support to our studies of Long-billed Curlews, Yellow-billed Cuckoo and Forest Service woodpecker surveys, as well as lending a hand at Lucky Peak this fall. Tempe also helped coordinate a collaborative effort to establish a new raptor count site in Djibouti, which hosts one of the largest concentrations of migrating raptors in the world.

ver increasing demand for IBO education and outreach lead to the hire of Heather Hayes, who headed up the “Curlews in the Classroom” program during the 2015-16 and 2016-17 school years (read more about Curlews in the Classroom in this article). She also worked this past fall to schedule and host all the visitors to Lucky Peak, and has been a huge help with developing outreach efforts at the Boise River site.

Also new to the IBO team is Teague Scott, former Lucky Peak Trainee of 5 years. Teague was accepted into the MS in Raptor Biology program at Boise State and will be assisting IBO with its vulture research in Mozambique at Gorongosa National Park. Look for other graduate students to begin IBO projects in 2018 in Wyoming and at Duck Valley Indian Reservation!

We are pleased to welcome these new IBO team members and are honored to work with such a talented, intelligent, and driven group of people!  

Thank you all!

Tribute to Gary Robinson – IBO Super-volunteer

By Jay Carlisle

To read the tribute to Gary written by his family, follow this link.

On March 30th, the IBO family lost one of our greats – Gary Robinson, who has been one of the most valuable and dedicated volunteers in our history.  Gary passed after a battle with pancreatic cancer and we, along with his family and many friends, will miss him greatly.  It’s important to point out that he didn’t “lose” the battle to cancer – he was active, happy, and at his creative/mischievous best until his last few days!

Gary at Lucky Peak. Photo by Marissa Buschow

Gary showed up on Lucky Peak unannounced one day in August 2004 and told us he had banding experience and wanted to get involved if we’d have him.  At first glance, I wasn’t sure if this “old-timer” would be up for it but he quickly proved himself!  We went on a few net runs together and he demonstrated his ability to quickly extract birds from mist-nets and, though he huffed and puffed at times, he was always able to hike the trails to the nets.  It wasn’t long before he joined Carol and Dave Wike to form the “Three Amigos” – our team of ever-reliable volunteers that have been invaluable to IBO’s long-term banding studies for most of our 20+ year history.  They’ve been around for almost every MAPS (Monitoring Avian Productivity and Survivorship – a continent-wide breeding season protocol) banding day, lots of early-season days during our Lucky Peak fall migration project, and – more recently – became stalwarts of our hummingbird monitoring project.  Through all this effort, they’ve all been instrumental in helping us train scores of seasonal field assistants and the next generation of IBO volunteers while being invaluable members of the team themselves.

The Three Amigos! Dave and Carol Wike with Gary

Gary, in particular, was well-known for his “magic fingers” at the mist-nets.  Field assistants would often exclaim, “How did he just do that?!” after he’d removed a tangled-looking bird from the net in 10 seconds or less, sometimes with one hand!  Many field assistants fondly remember net runs with Gary as he effortlessly removed 75% or more of the birds in a given net in the same amount of time as they got the rest and, if they were lucky, he shared some of his secrets too!

Gary with a “small” load of birds he extracted at the Boise River site

Just as much, we’ve all enjoyed the many stories from Gary’s younger days – a sip of Lord Calvert in the evening often unlocked a story or 3 for the Lucky Peak crew :)  He was a veritable Swiss Army Knife of a man who tried and excelled at many professions during his career, starting as a Marine out of high school and, among other roles, enjoying spells as a biologist, police officer, zoo keeper, game warden, school teacher, and animal caretaker at a retirement home.  Similarly, he also carried everything you could think of, and more, in his jeep– so much so that if we ran out of something at Lucky Peak, we asked Gary as the first option.  He had a mischievous side as well, pulling pranks such as placing small sticks, pine cones, or even a lizard into bird bags and delivering them as if they were birds, usually with a straight face – and maybe a wink later.  We also heard several humorous stories about how he and the love of his life, Sandy, re-found each other after several decades – I’m so glad they did and, Sandy, thanks for sharing him with us!

Gary with just a few of the many Lucky Peak songbird banders he mentored over the years

Most of all, Gary was a loving friend to all of us and we will miss his big heart as much as his deft skills with the tiny birds we study.  As Sandy said to us as we gathered with her and Gary on his last day, “he’ll be with you when you go up to Lucky Peak” (certainly for hummingbirds and the river site too!) and I’m sure I’ll ask him for help the next time I’m struggling with a tangled bird.  We love you Gary and thanks for EVERYTHING!

 

At the request of his family, memorials, in lieu of flowers, may be directed to the Intermountain Bird Observatory. We’ve started a Gary Robinson memorial fund. Our mailing address is 1910 University Drive, Boise, ID 83725-1515. Please include a note letting us know if you are donating in Gary’s name.

Curlew Naming 2017

We held a contest to name our pair of birds that live on the Orchard Combat Training Center south of Boise. Read more about HH and KA on the “OCTC pair” tab on our curlew profiles page.

This year we asked schools that participated in our “Curlews in the Classroom” program to come up with name ideas. Check out their creative ideas below.

After a Facebook vote, our winning names were Zeus and Athena! Way to go Middleton Middle School :)


Names for HH

HH the curlew

Ginger–from Gilligan’s Island! (Marsing Elementary Kindergarteners)

Athena–The Goddess of Wisdom, War, and Craftsmanship. (Middleton Middle School 7th graders)

Rose–Signifies beauty, elegance, favor, grace, and kindness. (Middleton Middle School 7th graders)

Denise–named after their teacher. (Trail Wind Elementary School)

Bella–after the Twilight movies (Shadow Butte Elementary 3rd grade)

Valentina–because it is a Mexican name and curlews spend most of their time in Mexico (Andrea, Andrea, JJ and Alex from the Parma Learning Center after school program)

Frost–Frost is a good female name because the females leave Idaho first before the frost.  When females are on the nest, they freeze when predators come close. (Homedale Middle School)

Star— The star garnet is the state gem of Idaho. (Homedale Middle School)

Fluffy–because 4th graders like cute names, and curlews have fluffy feathers! (Trail Wind Elementary 4th grade)

Phenomenal birding and other wildlife in Nicaragua, February 2017

By Jay Carlisle

Golden-hooded Tanager

Golden-hooded Tanager at El Jaguar

I’m lucky in that I am able to fulfill my passions for birding and international travel most years and it’s always fun to visit new places.  This started with a birding trip with friends to western Mexico almost 20 years ago, then Panama and Peru the next 2 winters, and I’ve been addicted since.  In recent years I’ve started co-leading 1 or 2 group trips each year, starting with trips to Guatemala and Trinidad & Tobago in which I served as an “apprentice guide” assisting my friend Alvaro Jaramillo of Alvaro’s Adventures.  Alvaro taught me many key aspects of guiding and we’ve continued to collaborate since, which has included me running most of “my” trips through his company, sometimes piloting new itineraries and other times benefitting from trips he’s already planned.

In April 2016, I met Liliana Chavaria-Duriaux (Lili) and Georges Duriaux, owners of the El Jaguar coffee farm and private forest preserve in Nicaragua, at a bird conservation meeting in Guadalajara, Mexico.  We quickly hit it off, especially while on a birding field trip, and we soon decided to collaborate on a birding trip for some of my Idaho birding friends to visit Nicaragua – a country I’ve long wanted to visit, especially after flying over the extensive forests on the Atlantic/Caribbean slope on return trips from Panama and Costa Rica.

El Jaguar Reserve

Georges and Lili worked with Alvaro and I to create a diverse and exciting itinerary to explore four key regions of Nicaragua: (1) the north-central highlands, (2) the shores of Lake Cocibolca (aka Lake Nicaragua), (3) the Caribbean lowland forests, and (4) the Pacific slope.

The lush tropical forest at Refugio Bartola was destroyed in some areas by Hurricane Otto

One twist worth noting is that Hurricane Otto made landfall in November 2016 and affected many forest areas in southeastern Nicaragua, including blowdown of canopy trees and this affected areas of Refugio Bartola and the nearby Reserva Biologica Indio Maiz.  Lili and Georges initially worried that we’d struggle with forest species there but patches of intact forest remain within relatively short walking distance of the lodge and we still found amazing diversity there.

Pale-billed Woodpecker

Though we didn’t see every bird we hoped for (does this ever happen? :-), the trip far exceeded my expectations in terms of bird diversity and was a great experience overall.  Lili and Georges were great to travel and bird with, we employed knowledgeable local guides, we stayed in comfortable lodges/hotels, we ate great food, and the group made for a fun and cohesive birding team!

Enjoying the view of Rio San Juan during breakfast at the remote Bartola lodge

Highlights:

  • We recorded 366 bird species during 10 birding days – of these, 14 species were “heard only” (i.e., owls, Great Tinamou, and a torturously distant Three-wattled Bellbird) and 15 were only seen by 1 or 2 observers but 337 were species that were seen by all or most of the group!

    The forests of El Jaguar support a rich bird community, including wintering Golden-winged Warblers!

  • Some of the most exciting/interesting species included:
      • The near-endemic Nicaraguan Grackle (San Miguelito)

      • Green Ibis (Bartola)
      • Pacific Parakeets coming to roost near a waterfall in El Chocoyero

  • Montibelli Private Reserve (2 nights, 1 full day)

The itinerary required relatively extensive travel, including a couple of long travel days moving between regions, but we timed it to be able to bird at least the morning and/or late afternoon of the travel days – and the boat trips on the Rio San Juan (to/from Bartola) provided many good sightings.  And, we tried to balance the travel with multiple night stays at several places.  Importantly, we continued to find multiple new species on each day of the trip and the group stayed excited/engaged throughout.

All in all, I highly recommend Nicaragua for birding exploration!  It hosts an impressive diversity of habitats and birds, including a great mix of Neotropical migrants and species characteristic of both further north and south in Central America, and some great birding destinations.  Ask Alvaro if you’d be interested in going to Nicaragua :)

That’s why they call it Lucky Peak!

Here’s the story of the MM14 fire:

Updated 9/13/16

Most Important info:

  • Lucky Peak is safe and was not burned!
  • Highland Valley Road (the only driving access to the peak) has been closed until at least Spring 2017. Here’s a map of the trail closure.
  • Lucky Peak is closed to visitors for 2016. Please check out our Boise River banding dates for 2016. We look forward to seeing you on the peak in 2017!
  • Please do not hike to or otherwise enter any of the burn areas. We need to stay off and let habitat rehabilitation begin. Sign up to help with restoration here:
  • Our hawk trapping and owl gear burned in a storage shed off of Highway 21.  Thanks to your generosity, we were able to restore our projects after the fire!  ponyup.boisestate.edu/ibofire

Tuesday–the fire starts

On Tuesday, July 19th, the Milemarker 14 fire started along Highway 21. Shortly after the smoke appeared our crew evacuated our Lucky Peak station, taking only the songbird banding data sheets with us. Our last crew member made it out just in time before the fire engulfed Highland Valley Road.

Watching from town we worried as the pillar of smoke got closer and closer to the peak.

Capture

We saw firefighting planes dropping retardant close to our camp…through a scope we could even see that retardant had painted our outhouse and gate bright red. We called the Boise River WMA Manager, Krista Muller, and learned that she and her crews were safe. However, they left the WMA offices along Highway 21 at the last minute, chased out by flames that were approaching the headquarters. Krista said that as she was leaving she watched our storage shed, containing all our Raptor and Owl trapping gear, go up in flames.

After dark we returned to Municipal Park in Boise check on the peak again…it calmed our nerves that we could not see any flames or vehicles lights. We hoped the fire was dying down and moving away from our station. We watched the news and social media all evening, waiting for word about the peak. Going to bed that night, we feared the worst…we had heard from a few sources that the peak was expected to be engulfed overnight.

Wednesday–0% contained

As soon as daybreak came on Wednesday we rushed to a view point to see whether the habitat around the peak was still intact. We were relieved to see that all appeared well…there were still trees visible and the smoke had moved farther away.

Although our camp on the peak remained unburned, we received reports throughout the day confirming what Krista had said about the damage done to the Boise River WMA offices. Dramatic photos appeared on social media of flames engulfing the offices and our equipment. Sadly, we also learned that a woman lost structures on her property as well, although firefighters were able to save her home.

Thursday–progress

Thursday the 21st we were still watching the fire with caution. Hot weather and wind moving in to the area are not good for fire suppression efforts but we knew the firefighters were working hard to keep fire away from our station. By the end of the day we were impressed to see they had the fire 80% contained!

News updates continued, including our first aerial view of the fire’s extent. We realized just how lucky we were that our site was saved from the fire! In this image you can see Lucky Peak and our station in the top right, with only about 1km of land separating our camp and the burn.

Friday–almost out

Today, Friday the 22nd, firefighters continue to work to reach 100% containment. We watched from town, catching glints of firefighting vehicles traveling up and down Highland Valley Road, searching for hotspots and putting out any still-smouldering patches. By the end of the day Friday we hope to see 100% containment.

Saturday–surveying the damage

Saturday was a big day for us. Along with an escort, our crew returned to Lucky Peak for a brief visit to get our gear and assess any damage done by the fire retardant that was responsible for saving our camp.  We saw a lot of burn damage along Highland Valley Road. Firefighters used the road to stop the fire from spreading farther west. Our crew is being given special access to the road but please remember that the road is closed to allow for restoration work, and to protect the fragile burn area.

Although fire is a natural part of Idaho ecosystems, rejuvenates forested habitats, and creates a rich habitat mosaic for many bird species, we are saddened by this fire for a few reasons:

  • Climate change has brought hot, dry weather and unnaturally increased the likelihood and frequency of burns throughout the west. Our ecosystems are not able to adapt quickly enough to handle the effects of climate change.
  • Irresponsible and preventable human actions are often the cause of these fires, rather than natural triggers.
  • Sagebrush ecosystems evolved with infrequent, low intensity fires. These more frequent (human caused) hotter, and larger (cheatgrass-fueled) fires are not a part of natural, healthy Sagebrush Steppe communities.
  • Because of Cheatgrass and other human-introduced species, this area will require careful rehabilitation by humans (sign up to help here!) to restore healthy ecosystem function. Invasives prevent the natural regrowth of shrubs like Sagebrush and Bitterbrush that historically returned on their own after burns.
  • The riparian and steppe habitat lost will have impacts on breeding and migrating birds.
  • The loss of 4,300 acres of winter feed for ungulate populations will have repercussions for generations.

Moving forward

We worked with the great folks at Boise State University to start up an emergency PonyUp campaign, and were completely overwhelmed by the amazing support from all of you! After meeting our initial goal of $5,000 in the first day, we extended our goal and ended up raising over $19,000!

The funds raised in this campaign will go toward meeting our insurance deductible, recovering lost donations we would have received from visitors if Lucky Peak was open to the public

We are so thankful to all of you for your continuous support, concern for our safety, and immediate offers to help! As we continue to assess the damage we will share new updates with everyone about our needs.

Helicopter habitat restoration seeding

Restoration of the WMA has begun. In early September, helicopters were used to seed the burned area and cover it with straw to help reduce erosion.

What happens in Vegas…

After a busy season of curlew and other work, we’ve finally had some time to sit down and write some more stories from the curlew project. This blog post shares the story of two adventures, from the viewpoints of our Research Director, Jay Carlisle, and curlew crew technician, Ben Wright.

By Jay:

We’ve had such enormous success with our Long-billed Curlew satellite telemetry study since 2013 that it’s hard to find reason to complain or wish for more. And, as the curlews we are tracking started leaving breeding areas in Idaho, Montana, and Wyoming from the second week of June through early July, the map got more and more exciting and interesting by the day. BUT, during early July, a time when I was just barely catching my breath from an intense 3 months of non-stop fieldwork and travel, I started looking into the details of the satellite transmitter data and soon noticed that two (of a total of 21) transmitters were not moving anymore. Because both of these transmitters were attached in May, it seemed unlikely that the harnesses had fallen off so I became concerned right away.

We’ve previously been able to find five downed transmitters and, in four of the five cases, the news was bad: two had been shot in their breeding area, one had most likely been killed by a raptor soon after arrival in California, and one had died of unknown causes in an agricultural field in California. (The fifth was a happy ending) In all of these cases we were ultimately able to re-deploy the recovered transmitter – and since these transmitters cost over $3,000 each and refurbishing them, if needed, can cost as little as $250, recovering a transmitter can be a real cost savings while allowing us to collect data from another migrating curlew. Thus, it was a no-brainer for me to send Ben Wright, our experienced and all-star curlew nest finder, on a rescue mission or two.

Henrietta’s lost mate

First stop was the Flat Ranch – a Nature Conservancy preserve near Henry’s Lake, to the west of Yellowstone. We had previously tracked a breeding female curlew (“Henrietta”) from Flat Ranch in 2014 and we returned this year to deploy an additional transmitter and study the reproductive success of curlews nesting at the ranch. Erica and Hattie, the two curlew crew field technicians who worked this site this year, had found Henrietta’s nest (with an almost unheard of five eggs!) so we were able to catch her mate and deploy a transmitter on him in late May.

Their nest hatched in June and both parents were seen tending/defending their chicks soon thereafter. Unfortunately, it was his transmitter that showed no movement by early July – and the battery soon died which was going to make the search MUCH harder.

Nonetheless, Stephanie and I created maps showing the latest high-quality locations and sent them to Matthew Ward (great colleague and the Preserve Manager for TNC’s Flat Ranch). He and some high school-aged volunteers spent parts of a couple days traversing the most likely area. When they had no luck, I sent Ben with a rented metal detector to see if he could have any more luck. He thoroughly searched a full 2.5 days, including crawling through a culvert under Highway 20/26 to see if a predator/scavenger might have taken a carcass in there! His search produced not even a curlew feather so we had to be content scratching our heads about this one (& I was wishing I’d discovered the issue sooner!).

We continued to hope the transmitter would turn on again, but had to shift our attention to another transmitter problem and put this one on the back burner.

Heading to Vegas

Meanwhile, a female we had trapped from the nearby Shotgun Valley, just west of Island Park, had begun her migration in late June and her trajectory took her towards the southwest – seeming likely she was heading to where many of our other birds are, either in the Imperial Valley agricultural lands near the Salton Sea or along the northern part of the Gulf of California. I noticed that her last transmission was from a mountain in very southern Nevada and at first I assumed this was an in-flight location while she was migrating past. When the signal didn’t move for a couple days, I got suspicious as the terrain (steep and rocky desert with some vertical cliffs) didn’t look like curlew habitat.

I started contacting local biologists, including Joe Barnes of the Nevada Department of Wildlife (NDOW) and Melanie Cota of BLM, to see about the land ownership and if a search mission would be feasible. Joe kindly offered to take a quick hike to the spot (~an hour’s steep hike from the nearest road) and came back with news that didn’t surprise me – he saw and heard both juvenile and adult Peregrine Falcons using the cliff areas, adding some circumstantial evidence that a falcon might have been the reason this curlew & transmitter had ended up on a steep mountain. But, he didn’t find any carcasses or transmitters so I still had to decide if it was worth sending one of us on a recovery mission. I couldn’t go because our set up for our annual Lucky Peak songbird migration study was set to start the next day so it’d have to be someone else – and maybe ideally with some climbing experience just in case. As I was weighing up expenses and our chance of finding the transmitter, I gave Ben a choice: more data entry, or a bit of an adventure? It was a no-brainer for him. J

My decision was made easier by the fact that our friend Julie Baughman, who had attended a raptor workshop that Jessica taught last fall, is a pilot for Southwest Airlines and – because she put in some serious hours of volunteering after the workshop – she had been able to donate a couple of passes on Southwest for IBO to use. Thanks Julie & Southwest! Then it was just a matter of hotel, rental car, gas, food, etc. – all costs that would be minor if we could find the transmitter. So I looked at the transmission schedule of the transmitter (picking a couple straight days on which the transmitter would be “talking” during daylight hours), booked Ben a seat on a flight, and sent him to Las Vegas!

By Ben:

We started the downed transmitter search looking at a map Stephanie had created. Her map had the most accurate locations that the transmitter had sent out. There was a cluster of six points near the top of a ridge. We decided that at the cluster would be the best place to first search for a signal coming from the transmitter.

In the afternoon on July 14th I flew down to Las Vegas from Boise. I rented a car at the airport and drove out to Primm, Nevada (a small Casino town on the California, Nevada border, southeast of Las Vegas). The transmitted points we’d received from the transmitter indicated that it had gone down in the mountains, about five miles northwest of Primm. I arrived at my hotel in Primm around 10:30pm. It was difficult to sleep with anticipation of the following day. By five forty-five the next morning, I was wide-awake.

I packed up my stuff and checked out of the hotel. A few days earlier I’d studied a map and found what appeared to be the best way to access the area with a vehicle. My route wound through a large gravel pit on the northern edge of Primm. It continued out into the desert where it turned into a very washed-out two-track that went along an underground gas pipeline. There were a couple of places along the two-track where I wasn’t sure whether or not my vehicle was going to make it. About a quarter mile south of the point that I’d picked on the map for parking, a barbed wire fence crossed the two-track. The fence had been cut and closed back up in the past but I’d left my fencing tools behind when I boarded the airplane in Boise. The fence was only about half a mile south of the original spot I’d picked for starting on foot.

I was feeling pretty good about my early start until, while loading my pack I realized that I’d lost an essential piece of equipment. At some point between the IBO office in Boise and where I had just parked, I had somehow misplaced the cord that connects to the receiver to its antenna. The rest of the equipment I had would be of almost no use without it. I quickly searched through my gear multiple times without finding it. I drove back to Primm as quickly as I safely could on the rough, washed-out two-track. I tried to re-trace my steps as I ran back into the Casino hotel, where I’d stayed. A nice lady at the counter gave me a key to the room and I was extremely relieved to find the cord coiled on the counter next to the TV and microwave cords.

By the time I got back to my start point, the outside temperature seemed to be quickly increasing. Shortly after leaving the car I was starting to worry about the amount of water I was carrying. With the heat, the steep terrain and my hurried pace (trying to make it to the start point before the transmitter began its four-hour transmission cycle), I was drinking a lot of water.

The terrain was much steeper than I’d thought it would be after viewing the satellite images of the area. A few hundred meters from the car a snake rattled out of my path. He served as a good reminder of the things I needed to watch out for. The rock that made up a large part of the steep ridges turned out to be very coarse and easy to grip while I was climbing up. With the ease of climbing, I was able to reach the top of the ridge more than an hour before the transmitter was estimated to turn on.

The first thing I did when I arrived on top of the ridge was find shade in one of the many shallow caves that are formed in the rocks.   From my sheltered lookout at the top of the ridge I could hear, every once and a while, what sounded to me like a young raptor begging for food. I’d heard from the biologist who’d come out to look for the transmitter before me that there were a fledgling and adult Peregrine Falcon in the area.

After I’d begun searching, it took me a while to locate the signal coming from the transmitter. While holding the antenna out in front of me, I would work my way out to the ends of the jagged rocks that stuck out off of the main ridge. I went back and forth a couple of times, from one side of the ridge to the other, in an effort to determine which side it was on. The points on our map had indicated that it was most likely located somewhere on the south side of the ridge. I searched for about an hour, without finding a signal.

I was sitting at the top of the ridge, near the start point, trying to decide what my next step should be since I hadn’t heard any signal. It was then that I finally picked up the signal. I was very excited when I heard the first signal strength readout. The transmitter appeared to be located where I’d thought it would most likely be after I’d seen the map. It was also much closer than I’d thought it would be when I first picked up its signal.

Before leaving Boise, Stephanie had warned me about an issue that can arise while operating this kind of equipment in steep terrain. She’d said that the signal could deflect off of cliffs before being picked up by the receiver. This effect could trick the person operating the receiver into thinking that the transmitter was closer or in a different direction than it actually was. Just a few minutes after picking up the transmitter’s signal, the receiver’s proximity read-out was indicating that I was within fifteen meters of the transmitter. It seemed unlikely to me that I could already be that close. Due to how near I was to steep terrain, I assumed that the signal from the transmitter must be bouncing off of the rock in the area.   I decided to walk a ways further south. When that didn’t work I tried moving to the east of where receiver had first taken me after picking up the signal.

Each time I walked in a different direction, the antenna indicated that I needed to move back in the direction of where the receiver had given me the highest proximity readout. After about forty-five minutes of walking around, I gave in and started searching the smaller area where the signal was strongest. The only clue that I’d come across up to that point was what appeared to be a body feather. The feather was small and slate-gray in color—obviously not from a curlew.

After a frustrating fifteen minutes of hiking up, down, back and forth across the steep slope, trying to find where the signal was best, I saw what I’d been looking for. Sticking up from among some brown, sun dried grass was a Curlew’s wing.   It appeared to me that the bird’s skeleton had been picked clean by a raptor. Even the pad that lies under the transmitter to protect the bird on the bottom had been chewed by whatever predator had eaten the Curlew. Bones and feathers were mostly all that was left of the bird.

The transmitter sat about a foot from the bird’s remains. It was sitting upright on a rock with its solar panels sparkling in the afternoon sun.   Because of my assumption that the equipment had been encountering interference, I had ended up searching at least another forty-five minutes longer than would have been required. Before leaving, I took several pictures of the bird’s remains and transmitter then collected the transmitter, metal leg band and plastic flag that was placed on the bird’s leg for identifying her at a distance. While I was picking up the equipment, I found another small feather, the same gray color as the first. This seemed to be good evidence that it was probably a Peregrine Falcon that had eaten our curlew.

I then quickly made my way back down the mountain to make the five-thirty flight out of Las Vegas. As I worked my way down towards the car, the heat rapidly grew more and more intense.

A few hours later, as I was preparing to go through security at the airport, I worried that the luggage scanner might damage the valuable transmitter. When I explained my situation and what the device was to one of the TSA agents I was assured that the transmitter was definitely going to have to go through the scanner, regardless of any damage that might occur. I was relieved the next day when Jay texted to inform me that the transmitter was still transmitting.

A Return to Flat Ranch

I had spent three days in Island Park looking for the transmitter that went down at Flat Ranch, but since it wasn’t transmitting I couldn’t find anything. Then, soon after I returned from Vegas, the transmitter unexpectedly started transmitting again around August third. A few people from the Flat Ranch Preserve went out and where unable to find it, so Jay sent me out with the transmitter-locating equipment to try. This was only my second time using the equipment.

This time seemed to me like it would be much easier. The search area was, for the most part flat and right next the highway, instead of being on steep cliffs like the bird from Primm. The only vegetation over most of the area is very thin grass that stands about a foot tall. As soon as I turned on the equipment it started receiving a signal.

While I was following the signal and nearing the transmitter the preserve manager’s dog walked over and started sniffing at something that turned out to be the Curlews wings. The rest of the bird’s carcass, the bands and the transmitter were there as well. From the time I turned on the receiver it had only taken us about an hour and a half to find the transmitter.

DSCF1389

The bird appeared to have been hit by a car traveling on the highway. The highway is about a hundred and fifty meters to the west of where we found the remains of the bird. The skeleton was very broken up and even the plastic flag that had been placed on the bird’s leg for identifying him at a distance was broken. Based on what we observed, we concluded that the two small solar panels on the transmitter must have been covered by the bird’s carcass during the time that it wasn’t transmitting.  When we found it, the transmitter was about a meter from the carcass. A Raven or some other predator may have pulled the transmitter away from the carcass to where sunlight was able to reach it.

In closing, though we are very sad to have lost two curlews, we have gained important information about mortality risks to curlews and we’re fortunate to have been able to recover both transmitters for use in 2016.
