Anna’s Hummingbirds are regular visitors to Tucson hummingbird feeders; they are mostly green and gray. The male's head and throat are covered in iridescent reddish-pink feathers that can look dull brown or gray without direct sunlight. The iridescent throat patch of male hummingbirds is called a gorget. The Anna’s gorget extends over its head, making it more of a balaclava than a bib. Oddly, female Anna’s have a tiny red gorget—females of most species have none.
