OFFERTO DA MERLIN

A large, compact, and powerful martin, gray-brown above, with contrasting dark "armpits." Tail is square with white windows prominent when spread. Vigorous, fast, and powerful flier, constantly twisting and turning as it patrols the sides of mountains and gorges. Frequently gives a hard, dry “chrrt.”
