The common cuckoo is an obligate brood parasite; it lays its eggs in the nests of other birds. Hatched cuckoo chicks may push host eggs out of the nest or be raised alongside the host's chicks. [17] A female may visit up to 50 nests during a breeding season. Common cuckoos first breed at the age of two years. [2]
Nest of Polistes dominula, host to the cuckoo wasp P. semenowi [a] One of only four true brood-parasitic wasps is Polistes semenowi. [a]. This paper wasp has lost the ability to build its own nest, and relies on its host, P. dominula, to raise its brood. The adult host feeds the parasite larvae directly, unlike typical kleptoparasitic insects.
A pallid cuckoo juvenile being fed by three separate foster-parent species. About 56 of the Old World species and three of the New World cuckoo species (pheasant, pavonine, and striped) are brood parasites, laying their eggs in the nests of other birds [24] and giving rise to the metaphor "cuckoo's egg". These species are obligate brood ...
The common cuckoo brood parasite removing the reed warbler eggs from their own nest. Egg tossing or egg destruction is a behavior observed in some species of birds where one individual removes an egg from the communal nest. [1]
Cuckoo bee from the genus Nomada. There are many lineages of cuckoo bees, all of which lay their eggs in the nest cells of other bees, often within the same family. [7] Bombus bohemicus, for example, parasitises several other species in its genus, including B. terrestris, B. lucorum, and B. cryptarum. [8]
Species in this subgenus are obligate parasites of other bumble bees. The females have lost their pollen-collecting corbiculae [3] [4] and their ability to rear their own brood. Cuckoo bees have also entirely eliminated the worker class, producing only reproductive males and females. [3] This form of parasitism is known as inquilinism.
The channel-billed cuckoo (Scythrops novaehollandiae) is a species of cuckoo in the family Cuculidae. It is monotypic within the genus Scythrops. [3] The species is the largest brood parasite in the world, and the largest cuckoo. [4] It is found in Australia, New Guinea and Indonesia; additionally, it is vagrant in New Caledonia and New Zealand.
The cuckoo (bird) is the most familiar example of a brood parasite, hence P. semenowi's common name, the cuckoo wasp. P. semenowi has lost the ability to take care of its own young, [ 7 ] so if an overwintering female fails to find a host nest to usurp, she leaves no offspring.
