This is going to be “Hummingbird Week”.
Costa’s hummingbird (Calypte costae) can be found in the brushy foothills and chaparral in desert and semi-desert regions. It breeds in the Sonoran and Mojave Deserts of California and Arizona and is be found year-round in the arid regions of Mexico.
The male has an iridescent violet crown and throat patch (gorget). The gorget extends beyond the throat toward the back, which is greenish. The small, black tail lacks white tips. The throat and underparts of the female are white to pale grey. Sometimes her throat is blotched with a little violet.
Costa’s hummingbirds eat nectar.
Amazingly the heart of a non-resting Costa’s hummingbird can beat 500-900 times a minute.
Populations of Costa’s hummingbirds are slowly declining. Loss of habitat is considered a major threat to the survival of this small hummingbird.
Costa’s hummingbird was named for Louis Marie Pantaleobn Costa (1806 – 1864), a French statesman, archeologist, historian and ornithologist, who was particularly interested in hummingbirds.
This male Costa’s hummingbird was photographed south of Tucson AZ.
