A rather retiring, unwary Hawk which nests in thick woods and is less
often seen in the open than the Red-shoulder, but, when migrating,
hundreds pass high in the air, with other Hawks. Its call is a high,
thin, penetrating whistle. It nests in late April and early May, laying
2-4 whitish eggs marked with brown.
