6 fascinating birds that trick others by laying eggs in their nests

The Common Cuckoo is a master of trickery. It lays its eggs in the nests of smaller birds like warblers. The unsuspecting parents then raise the cuckoo chick, often at the expense of their own offspring.

Native to North America, the Brown-headed Cowbird lays eggs in more than 200 species’ nests. The host birds feed and protect the cowbird chick, often unaware that it isn’t their own, which sometimes leads to their own chicks being neglected.

Found in Africa, the Greater Honeyguide targets hole-nesting birds like woodpeckers. It sometimes destroys the host’s eggs before laying its own. This aggressive strategy ensures that its chick receives all the food and care.

The Asian Koel lays its eggs in nests of crows and other corvids. The host birds raise the koel chick, feeding and protecting it as if it were their own, unaware that they are nurturing a parasite’s offspring.

The Black-headed Duck in South America and the Shiny Cowbird target other birds’ nests, especially smaller species. Their chicks are raised by unsuspecting foster parents, often outcompeting or harming the host’s young in the process.

The Shiny Cowbird, common in South America, targets nests of smaller birds. Its chicks often grow faster and demand more food than the host’s young, sometimes causing them to be neglected or pushed out, affecting the host’s breeding success.
