Greater Sage-Grouse (Centrocercus urophasianus) are of conservation concern across western North America. Little is known about the fidelity of individual birds to wintering areas across years for this species. We used GPS data from 31 female Greater Sage-Grouse to analyze migratory behavior and fidelity to wintering areas from 2015 to 2021 in southeastern Idaho. Mean duration of movements between summer areas and wintering areas was 11.2 d (SD = 10.5 d). Mean distance moved from summer areas to wintering areas was 61.5 km (SD = 22.0 km); mean distance moved from wintering areas back to summer areas was 54.6 km (SD = 29.6 km). Nine females did not return to the same wintering areas across consecutive years, and centroids of utilization distributions from 7 of those birds shifted by a mean of 35.5 km (SD = 11.7 km) between winters. Twenty-two of 31 females returned to the same wintering areas across at least 2 years. We were able to calculate utilization distributions for 19 of those 22 birds, and 15 of those birds had overlapping utilization distributions between years during winter. Additionally, 6 of 10 females returned to the same wintering areas across 3 years, and 4 of 5 females returned to the same wintering areas across 4 years. Our data quantify duration of migration for sage-grouse and highlight the importance of consistent wintering areas for individual sage-grouse across multiple years. Biologists can use such data to facilitate land-use planning and conservation of winter habitat for this species.
