The U.S. Fish and Wildlife Service is currently conducting research on trumpeter swans in Montana, Wyoming and Idaho to determine what is limiting breeding success and cygnet (juvenile) survival.
As part of the study the Service has banded and placed green collars on swans. Each neck collar has a unique number, which helps identify individual trumpeter swans. During the summers of 2017 and 2018 a total of 24 swans were collared across Camas, Grays Lake and Bear Lake National Wildlife Refuges in eastern Idaho.
The fish and wildlife service is seeking information on whereabouts of these birds throughout the winter. To date, collared birds have been sighted around American Falls Reservoir, at the south end of Bear Lake, at Bear River Migratory Bird Refuge in Utah and on Pioneer Reservoir near Bliss.
If you see a swan with a neck collar, please report the collar number to www.reportband.gov.
Your assistance in reporting collared birds will help us learn more about the ecology and survival of this important wetland indicator species.
