Madagascar Harrier-hawk

Tweet of the Day is the voice of birds and our relationship with them, from around the world. Chris Packham presents the Madagascan Harrier-hawk from Madagascar. Among the branches of a Madagascan forest, there's a flutter of wings and a flash of double-jointed feet. The Madagascan harrier-hawk is a striking bird, uniform grey above and finely barred beneath with black wing-tips and a white-banded black tail. There's a patch of sulphurous skin around its bill and eyes: and its long legs are also bright yellow. Those long legs help the harrier-hawk hunt for food that's beyond the reach of most other birds of prey. Using its wings for balance and twisting its flexibly jointed legs at seemingly impossible angles, the harrier-hawk inserts its talons into tiny holes, relying on its sense of touch to locate its prey. Madagascan Harrier-hawks do hunt more conventionally by gliding over the forest, seizing small birds, reptiles and mammals such as the Verreaux's sifaka.
