Wyoming hummingbirds begin southward migration for winter

As autumn approaches, various hummingbird species in Wyoming are beginning their southward migration to warmer climates in the southern United States or Mexico. Some species may travel up to 1,500 miles to survive the winter.

The Wyoming Game and Fish Department confirms that Broad-tailed, Rufous, and Calliope hummingbirds are established breeders in the state. The Black-chinned hummingbird is a suspected breeder, while Anna's and Ruby-throated hummingbirds have been spotted but lack confirmed breeding records.

Migration typically follows a pattern where adult males depart first, followed by females, and finally the young birds between September and mid-October. These birds travel approximately 23 miles per day, often utilizing tailwinds to assist their flight. Experts advise residents to remove hummingbird feeders once migration begins to avoid attracting bears, which may target feeders while preparing for winter.
