Cuculus canorus

Cuckoo - Ok not the best cuckoo image, but the best I have just now! They are very illusive and more often heard than seen. The common cuckoo is an obligate brood parasite. It lays its eggs in the nests of other birds. Hatched cuckoo chicks may push out host eggs out of the nest or be raised alongside the host's chicks. A female may visit up to 50 nests during a breeding season. This one perched in my garden in Co. Leitrim.
