Birds that lay their eggs in other birds' nests are called brood parasites. They don't build their own nests

These birds leave their eggs in "someone else's" nest and rely on the host birds to incubate and feed their young

This allows them to save time and energy, and also directly affect the reproductive success of their hosts

Some common brood parasites include cuckoos and cowbirds. Honeyguides can also be brood parasites

Cuckoos come somewhere between blackbirds and woodpigeons in size. About 50 species of cuckoos practise brood parasitism

The cuckoo has a long tail, pointed wings, and zygodactyl feet and can be 6-24 inches long

Honeyguides, also known as indicator birds, are found in Africa and the Himalayas
