小嘴烏鴉 Corvus corone

The quintessential big black crow, without obvious field marks. Juvenile Rook has longer, more pointed bill with more extensive feathering on base. Smaller than Common Raven, which has longer, wedge-shaped tail, heavier bill, shaggy throat, and deeper voice. Ravens soar and glide readily, whereas crows typically flap continuously. Common in varied open and semi-open habitats from towns and farmland to open woodland and moorland. Found in pairs or small groups; large flocks only at roosts. Typically gives raucous caws.
