How do cuckoos raise babies?
In Europe, a bird called the common cuckoo uses a sneaky strategy to raise its babies. First, a female cuckoo finds a nest built by a bird of a different species. For example, it might be a great reed warbler. Then, she sneaks into the warblers’ nest, lays an egg and flies away. The warblers often accept the new egg. Indeed, they take care of it along with their own eggs.
What is a brood parasite?
Brood parasites are “basically looking for foster parents, ” says Mark Hauber, a biologist. He studies animal behavior at the University of Illinois at Urbana-Champaign. The “foster parents” are also called “hosts.”. Those hosts then feed and protect the parasite’s offspring. Scientists find this behavior intriguing.

Are All Parasites Bad?
Of course, the findings aren't saying there are no bad parasites. For example, it's hard to see any benefits for the host if the interaction with another species kills it.

Overview
- Cuckoos are birds in the /kjuːˈkjuːlɪdiː/ family, the sole taxon in the order Cuculiformes /kjuːˈkjuːlɪfɔːrmiːz/. The cuckoo family includes the common or European cuckoo, roadrunners, koels, malkohas, couas, coucals and anis. The coucals and anis are sometimes separated as distinct families, the Centropodidae and Crotophagidae respectively. The cuckoo order Cuculifor…
Description
- Cuckoos are medium-sized birds that range in size from the little bronze cuckoo, at 17 g and 15 cm, to moderately large birds, ranging from 60–80 cm in length, such as the giant coua of Madagascar, the coral-billed ground-cuckoo of Indochina, the channel-billed cuckoo and various large Indo-Pacific coucals such as the goliath coucal of Halmahera, Timor coucal, buff-headed c…
Distribution and habitat
- The cuckoos have a cosmopolitan distribution, ranging across all the world's continents except Antarctica. They are absent from the south west of South America, the far north and north west of North America, and the driest areas of the Middle East and North Africa. They generally only occur as vagrants in the oceanic islands of the Atlantic and Indian Oceans, but one species breeds on …
Behaviour and ecology
- The cuckoos are for the most part solitary birds that seldom occur in pairs or groups. The biggest exception to this are the anis of the Americas, which have evolved cooperative breeding and other social behaviours. For the most part the cuckoos are also diurnal as opposed to nocturnal, but many species call at night. The cuckoos are also generally a shy and retiring family, more often …
