Cuckoos lay their own eggs in other birds' nests to trick them to care for their cuckoo-chicks. These birds, unaware that they have been duped, sacrifice their energy and time to feed and care for a ruthless imposter. They call this brood parasitism. The Midwick Cuckoos alludes to this--a silver object appeared in the village, then all women are discovered to be pregnant, they became "host" to these babies.
