American cuckoos are not brood parasites—they raise their own chicks.
Common cuckoos are more often seen than heard—their colouring allows them to blend in with the surrounding trees. Cuckoos are medium-sized, with a long black, white-spotted tail. They have short legs and wings, the latter of which are noticeably pointed. The predominant colour is grey and the belly is white, with dark stripes across it. Females and males are similar in size and appearance.
Cuckoos find most of their insect diet among bushes and trees. When females choose nests for their young, they make sure the owners of the nest are insect-eating, so that they can properly feed the young cuckoos.
Female cuckoos usually lay nine eggs, one at a time, in the nests of smaller birds such as robins, dunnocks, pipits and warblers. The term for an animal that lays its eggs in the nest of a member of its own or another species is “brood parasite.” If females do not have access to the nest long enough to lay the egg directly in the nest, they will lay it on the ground and carry it in their mouths to the nest at an appropriate time, then remove one of the eggs already there and dispose of it, so the number of eggs remains the same. She tries to match the other bird’s eggs as far as size and colouring, except in the case of the dunnock, who lays blue, non-spotted eggs. Approximately 12 days later, when cuckoo chicks hatch, these newborns toss the other eggs and/or hatchlings over the side of the nest. The new parents take care of the cuckoo chick as if it is their own, even though it grows to be much larger than they are in a short amount of time, and even outgrows the nest. In fact, by the time the chick is one month old, it has grown to 50 times the size it was at hatching. The chicks leave the nest at about this time. It is believed that the cuckoo is anatomically unable to brood its eggs, which explains why it places them with other birds.
Common cuckoos are good fliers and resemble hawks or falcons in flight, but are awkward on the ground. They are shy animals that live solitary lives, except during breeding season when they pair up with a mate.
Numbers are in decline due to pesticide use and habitat loss, but they are not considered a conservation concern at this time.
