Birds - Africaraw

Etosha National Park

African harrier-hawk (Polyboroides typus ), takes off after bathing at Klein Okevi waterhole. Etosha National Park, Namibia.
Biology Note:- They have unusual tarsal joints that allow them to use their long, unfeathered, & heavily scaled legs to snatch prey from narrow gaps in nests, trees, & rock crevices. The especially modified tarsal ("ankle") joint allows the leg to move back & forth. The Crane Hawk in southern america has evolved a similar limb structure & this is known as "convergent evolution" http://en.wikipedia.org/wiki/Convergent_evolution)
