The Snail Kite is found throughout tropical America, but in the United States, it is restricted to the southern half of Florida. Indeed, it used to be called the Everglades Kite. This video features an adult male (smooth gray), an adult female (more mottled), and a juvenile bird (streaked brown).
These birds are relatively rare, and always have been, with a population low in the 1960s of a few dozen birds. Today they number over 1000. The invasion of a large, difficult to handle, exotic snail replacing the native Apple Snail is their latest threat, although the birds can eat both kinds.
