[Crane Hawk]

Trans-Pantanal Highway, Mato Grosso, Brazil, August 3, 2010

Crane Hawks are pretty variable, as this bird demonstrates. It is a bit odd-looking, with the bicolored tail, changing band widths in the tail feathers, and only a hint of the typical wing crescents. Although they are often not illustrated, all of these features are known to occur. The full-size “Raptors of the World” does illustrate this tail pattern. I don't know if it's included in the field guide version.
