Nature Quiz - British Birds - Crows and Cuckoos (Questions)

The all-black carrion crow is one of the cleverest, most adaptable of our birds. The closely related hooded crow has recently been split as a separate species. With cuckoos, it is the male's call that is the very familiar "cuckoo". Generally, if you hear a cuckoo singing you will probably not see it until it stops singing, which is when it flies away from its song post.
