What is brood parasitism in birds?

BirdsReproduction

Quick Answer

Brood parasitism is when one bird lays its eggs in another bird’s nest and leaves the host to raise the chicks. The best-known example is the cuckoo.

The Full Story

Brood parasitism is a reproductive strategy in which a bird avoids parental care by using another species as a foster parent. The parasitic bird lays its eggs in a host nest, and the host may incubate and feed the chick as if it were its own. Common brood parasites include cuckoos, cowbirds, and honeyguides. Hosts and parasites often evolve an arms race of egg mimicry, nest defense, and chick recognition.
