The Western White-Winged Doves (Zenaida asiatica mearnsii) are a brownish-grey above and grey below, with a bold white wing patch that appears as a brilliant white crescent in flight and is also visible at rest. Adults have a patch of blue, featherless skin around each eye and a long, dark mark on the lower face. Their eyes, legs, and feet are red. They migrate into the Sonoran Desert to breed during the hottest time of the year because they feed on pollen and nectar, and later on the fruits and seeds of the Saguaro Cactus. Sonoran Desert, Arizona.
