[edit] Identification

53-63cm. Wings long and broad. Brown upperparts, paler, streaked head, brown-spotted white breast, and dark breast band. The legs are fully feathered. Wings are mostly pale below but in typical birds have a dark square at the base of the hand and in adults are dark-edged. Tail is white with one broad dark subterminal band and 0-5 additional narrow bands close the the subterminal band. In the American subspecies, a dark morph occurs where body and wingcoverts are completely dark but flight feathers and tail are quite typical, almost silvery white in this form. In all forms, a broad white uppertail is diagnostic (a narrow version of this can be seen in Common Buzzard) and most often, you should notice pale basis of primaries on the upperside of the wing.

[edit] Similar Species

Can be told from Common Buzzard in flight by the whitish tail with the single dark bar at the end. Is more inclined to hover than Common or Honey Buzzard.
