Family Accipitridae

family accipitridae variable hawk family accipitridae
Members of the family Accipitridae show a great deal of variation. Most accipitrids exhibit sexual dimorphism in size, with the females being larger than the males. This sexual difference in size is most pronounced in species that hunt birds, such as Accipiter hawks. In a majority of species, such as generalist hunters and rodent, reptile, fish and insect hunting specialists, the dimorphism is less. The beaks of Accipitrids are strong and hooked. In some species there is a notch or ‘tooth’ in the upper mandible. In all accipitrids the base of the upper mandible is covered by a fleshy membrane called the cere which is usually yellow in color. The tarsi of different  species vary by diet with species that hunt birds having long and thin tarsi, while species that hunt large mammals have much thicker, stronger ones, and have thick scales to protect from bites. The eyes are tube shaped and cannot move much in their sockets. In addition to excellent vision many species have excellent hearing, but sight is generally the principal sense used for hunting. The Accipitridae generally have a poor sense of smell. There are 24 genera and 47 species of birds within the family Accipitridae known to occur in Peru.
