アカガシラチョウゲンボウ Falco chicquera

A rather small but powerful falcon with fast and direct flight. It has a rufous crown, nape, and moustachial stripe. A wide yellow eye-ring is quite distinct. Its upperparts are pale gray, and fine barring adorns its white underparts, which are sometimes suffused with gray. This bird of the open country mostly hunts birds on the wing, targeting its prey from a perch, often bringing it down quite close to the ground.
