|Grey Hawk Buteo plagiatus
(aka Grey-lined Hawk Buteo nitidus plagiatus, Asturina nitidus plagiatus)
The Grey Hawk is distributed from south-west USA to north-west Costa Rica. See the distribution map at Birdlife International. It is found in a wide variety of habitat from the edges of humid forest to dry woodland.
It is a relatively small Buteo hawk with a wing span of 75 to 95 cms. In this photo it is above an American Black Vulture with a wing span of between 135 and 160 cms.
|Some authorities lump it with Grey-lined Hawk B.
nitidus but the HBW and Birdlife International checklist split it on the basis of its plain rather than barred crown,
nape, back and wings, its white rather than grey uppertail coverts and its longer call without the sudden drop in pitch in the middle.
