Checking the weather, social media sites, or online news is often
the first task people do after turning on their computers or mobile devices
each day. For several biologists in Jackson, Wyoming and the Intermountain Bird Observatory in Boise, Idaho, they anxiously check on the status of “AJ,” a
long–billed curlew that was fitted with a satellite transmitter on May 27 at
the National Elk Refuge.
Since receiving her transmitter, the curlew has hatched her eggs,
left the young with her male partner, and headed south. Her behavior is
typical: females usually abandon their
brood two to three weeks after they’ve hatched, leaving their mate to care for
the young. After a notable stopover in Utah, she is currently on Mexico's west coast, approximately 100 miles south of Mazatlan.
Long–billed curlews are North America’s largest shorebird,
recognizable by their distinctive long, curved bill. Though they spend their
winters on southern coasts and the interior of Mexico, they breed in grasslands
of the prairies and Intermountain West.
Long–billed curlews are listed as a “species of greatest
conservation need” in Wyoming and Idaho, and a species of concern with the U.S.
Fish and Wildlife Service. Their populations have
dwindled due to habitat loss and degradation. Satellite transmitters on the
birds can provide valuable insights into the species’ migratory routes,
migratory timing, and habitat requirements as well as allow scientists to develop
Eighteen curlews were documented on the National Elk Refuge in
early June, representing a significant concentration of the bird in western
Wyoming. One of them became part of a larger study done by the
Intermountain Bird Observatory, which involved equipping a total of nine
curlews with solar–powered satellite transmitters. The eight other birds were
captured in neighboring states.
AJ’s transmitter was generously paid for by the Meg and Bert Raynes Wildlife Fund, which supports research and habitat protection in Wyoming and
the Jackson Hole area. Because migration of long-billed curlews breeding in
Wyoming is largely undocumented, organizers hope to expand the project to
include more Wyoming–based curlews in the future.
