Can we sex crows? (6)

The previous 5 posts were of the Carrion Crows (Corvus corone). The male and female characteristics seem to hold true with other species. This photo is of a known pair of the Jungle Crow (Corvus macrorhyunchos). As indicated by the arrows, the upper bill of the male is hooked and longer than that of the female.
