The Tropical Kingbird, Couch's Kingbird, Cassin's Kingbird and the Thick-billed Kingbird are seen in separate regions along the southern states that border Mexico and into Mexico itself, with the Cassin's Kingbird having the most northern range. Lastly, the Gray Kingbird whose range is from the central areas of Florida and south into the Florida Keys.Kingbirds are feisty birds who will protect their territories against all birds. They are often seen divebombing the backs of crows and hawks. These birds are most often seen perched on service lines along roads and highways or on top of trees. They use these locations to hunt flies and insects where they are able to pick them out of the air as they fly by.
