The common skylark is a small bird of the passerine family Alaudidae. In all larks, the first toe has a very long, straight claw; the wings are long and pointed, as are also the inner secondaries of the wing. The skylark (A. arvensis) prefers open districts. It nests on the ground and lays spotted eggs.
