Rooks are omnivorous and feed on insects, earthworms, seeds and root crops, sometimes caching their food for later. How to Identify The Rook can be distinguished from the similar carrion crow by its pale bill and bare, grey bill-base, and the ‘baggy trousers’ of feathers around its legs. Where to Find The rook is a large crow that makes a big nest out of twigs in the top of trees. They often nest in villages and graveyards, but are also birds of farmland and grassland. How People Can Help To help populations of all our birds, The Wildlife Trusts are working towards a ‘Living Landscape’: a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener vision for the future by joining your local Wildlife Trust. Did you know? A group of rooks together is known as a parliament.
