Here in Northern California I am fortunate to have at least three of the western hummingbirds of North America visiting my yard. She is the latest of our local breeders, not nesting usually until mid-May. She will begin breeding in April. The male is the only hummingbird in North America with a rufous back.

In the mid-1970s, a local breeder was burglarized and a few of his birds escaped, after which the breeder released his remaining stock of about 50 birds 1.
