Brood parasitism (or egg dumping) is a reproductive strategy where a female bird lays its eggs in the nest of another bird, leaving the host to incubate and raise the chicks. This benefits the parasitic bird by avoiding the energy costs of parenting. It can occur within the same species or across different species, with well-known examples including cuckoos and cowbirds. | Hashem Al-Ghaili
