Conserving Montana's Sagebrush Highway: Long Distance Migration in Sage-Grouse.

摘要

Landscape conservation is the mechanism for conserving migratory wildlife in sagebrush ecosystems. We study further a greater sage-grouse (Centrocercus urophasianus; hereafter ‘sage-grouse’) population with the longest-known annual migration, a 240-km journey between summer range in north central Montana, USA, and Saskatchewan, Canada, to winter range north of the Missouri River. We learned more about grouse migration by asking: Do birds fly quickly through a corridor, or do they use stopover habitats within a larger migratory pathway?
