Northern Goshawk (Accipiter gentilis)
Accipiter is a genus of birds of prey in the Accipitridae family, many of which are named as goshawks and sparrowhawks (not to be confused with the American sparrowhawk, now more commonly known as the American kestrel, a type of falcon). They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.
Extant accipiters range in size from the little sparrowhawk (Accipiter minullus), in which the smallest males measure 20 cm (7.9 in) long, span 39 cm (15 in) across the wings and weigh 68 g (2.4 oz), to the northern goshawk (Accipiter gentilis), in which the largest females measure 64 cm (25 in) long, span 127 cm (50 in) across the wings, and weigh 2,200 g (4.9 lb). These birds are slender with short, broad, rounded wings and a long tail which helps them maneuver in flight. They have long legs and long, sharp talons used to kill their prey, and a sharp, hooked bill used in feeding. Females tend to be larger than males. They often ambush their prey, mainly small birds and mammals, capturing them after a short chase. The typical flight pattern is a series of flaps followed by a short glide. They are commonly found in wooded or shrubby areas.
An Accipiter was seen on 12 March 1994 south of the summit of Camiguin in the Philippines, where the genus was not known to occur. It may have been an undescribed taxon, but more likely it was not; it could simply have been a vagrant of a known species.
