You probably will hear a phainopepla before you see one, if you see it all. This resplendent feathered friend makes a melodic, rising wurp vocalization. When I hear that call, I look up high into the tree tops. I will often see this distinctive looking bird perched on a branch in the open, surveying its surroundings.
The name phainopepla derives from the Greek meaning shining robe. And shiny he is, the male of the species, with glossy black feathers and translucent white wing patches seen in flight. In contrast, the female and juvenile are a dull, mouse gray. They all have mesmerizing, crimson red eyes with solid black pupils, and a striking crest that resembles the hairdo of a punk rocker.
While the phainopepla regularly eats insects, its main source of nutrition is berries, primarily that of mistletoe. In the course of a day, a single bird may eat several hundred, which it swallows whole. A specialized digestive system can handle it all.
The phainopepla mimics the calls of other birds, which makes positive identification more difficult without visual confirmation. I wasnt surprised to learn that it imitates desert habitat birds such as the verdin and Gambels quail, since the desert is where I first knew them to reside.
