The bicolored hawk (Accipiter bicolor) is a species of bird of prey in the family Accipitridae. It is found in forest, woodland, second growth, plantations, and wooded savanna in southeastern Mexico, Central America, and northern and central South America (as far south as northern Argentina). Though generally uncommon, it is the most common species of Accipiter in most of its range, but it does not occur at altitudes above such as the highest parts of the Andes. Description At in length and in weight, it is significantly smaller than the northern goshawk of Eurasia and North America, and somewhat smaller than the Cooper's hawk of North America, but among the largest Accipiter hawks in Central and South America (only the rare grey-bellied hawk is larger). As in other Accipiter hawks, the female is far larger than the male. Adults are grey above with darker wings and crown, and a banded tail. The underparts typically vary from dark grey to very pale grey, but the southern subspecies can sometimes be rufescent below. The thighs are always pure rufous (not always easily seen), and the underwing coverts are white in the northern subspecies and rufous in the southern. Juveniles are very variable. They can be white, buff or rufous below, and sometimes with dark streaks. Their upperparts are browner than in adults, and the thighs are sometimes paler. Taxonomy The bicolored hawk is a species in the genus Accipiter and is included in the family Accipitridae. Three subspecies are currently recognized. The bicolored hawk is also closely related to the Cooper's hawk (A. cooperii) and the Gundlach's hawk (A. gundlachi); these three form a superspecies. Until recently, the Chilean hawk (A. chilensis) from the colder, southernmost South America was treated as a race of A. bicolor but due to its differences in habitat preferences and plumages from the bicolored hawk, A. chilensis is now considered a full species. Four subspecies of A. bicolor are acknowledged. These are: A. b. bicolor, which is found in Southeastern Mexico and south through northern South America. Adults have a black crown, slate upper parts and a blackish tail that displays two or three pale bars. The primaries are obscurely barred. A. b. fidens, which occurs in Eastern and Southern Mexico. It is morphologically similar to A. b. bicolor, but is larger in size and darker in color. A. b. pileatus, living in Brazil. Adults are similar
