Tropical Kingbird
Tyrannus melancholicus
Near Rio Rico, Sta. Cruz Co., Arizona, USA, 31 July 2010.
Tropical Kingbirds are an uncommon appearance in Arizona's sycamore canyons, and then mostly close to the Mexican border. They tend to show up during August or September, which is after their breeding season further south in Sonora, Mexico. The best way to see one is by checking rare bird alerts for southern Arizona. Tropical Kingbirds look a lot like our very common Western Kingbird, but the 'V' shaped notch in the black tail is distinctive.
