Hook-billed kite

The hook-billed kite (Chondrohierax uncinatus), is a bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, eagles, and harriers. It occurs in the Americas, including the Rio Grande Valley of Texas in the United States, Mexico, the Caribbean, Central America, and tropical South America.

It is a mid-sized, slender raptor with an invariably striped belly and banded tail but there is probably more individual variation in color and in size of bill than in any other species of diurnal raptor. Birds from beneath can look blackish or gray (especially males) and brown or brick-red (females) variously. This renders species identification at times extremely difficult. The downcurved hook at the tip of the beak is apparent on perched and low-flying birds. Weight can range from 215 to 397 g (7.6 to 14.0 oz) and length is 38–51 cm (15–20 in).
