Curlew Blog Posts

Long-billed Curlew populations, especially in southwestern Idaho, are declining. Because of this, they are listed as a species of concern, and a Species of Greatest Conservation Need in Idaho.

Threats like habitat loss and degradation, toxins, and human disturbance could be responsible for curlew declines. These threats may occur either on the breeding grounds or in wintering areas on the Pacific or Gulf coasts, or northern Mexico.
We are using Satellite Transmitters to answer some basic questions and find out why their numbers are decreasing:Photo by Liz Urban

  • What migratory routes do they take to reach their wintering grounds?
  • When do curlews from the Intermountain west arrive on their wintering grounds and where do they go?
  • What habitats do they use during migration and winter?

These answers will help us form conservation partnerships and make a plan to conserve curlews across Canada, the US and Mexico!

  •  We are learning that the curlews that breed in the Intermountain West spend the winter in two main areas: northern Mexico and California’s Central Valley, depending on whether they are from a more eastern or western population.
