Dunnocks are common little garden and hedgerow birds. They have a rather more colourful domestic arrangement than most birds, since females will often court other males whilst already mated with another. This ensures that her chicks will receive an adequate supply of food from both males, no matter who the father is. In the south of England, dunnocks are the preferred host for cuckoos. Even though cuckoo eggs look very different to their own, dunnocks unwittingly rear giant cuckoo chicks.
