The spectacular migrations of North America’s western half are under threat, says a new report from the Wildlife Conservation Society (WCS; the people who bring you the Bronx Zoo). These migrations include elk, caribou and calliope hummingbirds. The report doesn’t focus on specific threats to these long-distance migration as much as it points out which have the most potential to be saved by appealing to public interest.

The survey polled fish and wildlife biologists from 11 western states including Alaska, Washington, Oregon, Idaho, Montana, Nevada, Wyoming, Colorado, Utah, Arizona and New Mexico as well as drawing on the expertise of WCS’ own experts.
