Black-Chinned Hummingbird

Archilochus alexandri

The Black-Chinned Hummingbird are found during the summer breeding season in most of the Western USA. Many will spend winters either near the west coast of mainland Mexico, but some will remain year-round  in north-central Mexico and southern Texas.

As with most hummingbirds, the female is larger than the male. I’ve read reports that Black-Chinned Hummingbirds tend to build nests near active nest sites of larger birds of prey as a means to deter smaller, faster nest predators.

Closely related to Ruby-Throated Hummingbirds, there are some key differences. Black-Chinned seek their summer homes in western USA, while Ruby-Throated Hummingbirds go east during their spring migration. The gorget of the male Ruby-Throated is brilliant red, while those on the male Black-Chinned are pure black bordered with deep violet feathers. At rest, the primary wing feathers of the Ruby-Throat are narrow, while those of the Black-Chinned broaden to a wider tip.
