Brood parasites are organisms that use the strategy of brood parasitism, a kind of kleptoparasitism found among birds, fish or insects, involving the manipulation and use of host individuals either of the same (intraspecific brood-parasitism) or different species (interspecific brood-parasitism) to raise the young of the brood-parasite. This relieves the parasitic parent from the investment of rearing young or building nests, enabling them to spend more time foraging, producing offspring etc. Additionally, the risk of egg loss to raiders such as raccoons is mitigated, by having distributed the eggs amongst a number of different nests. As this behaviour is damaging to the host, it will often result in an evolutionary arms race between parasite and host.
Famous quotes containing the words brood and/or parasite:
“I go into my library, and all history unrolls before me. I breathe the morning air of the world while the scent of Edens roses yet lingered in it, while it vibrated only to the worlds first brood of nightingales, and to the laugh of Eve. I see the pyramids building; I hear the shoutings of the armies of Alexander.”
—Alexander Smith (18301867)
“When the ivy has found its tower, when the delicate creeper has found its strong wall, we know how the parasite plants grow and prosper.”
—Anthony Trollope (18151882)
