Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
The American robin rejects cowbird eggs, so brood parasitism by the brown-headed cowbird is rare, and the parasite's chick does not often survive to fledging. [41] In a study of 105 juvenile robins, 77.1% were infected with endoparasites, Syngamus sp. being the most commonly encountered, in 57.1% of the birds. [42]
The female robin will make the nest, and while she lays and incubates the eggs, the male will feed the female for a rest. Eggs are laid between early October and late December. A second clutch may be laid if the first is unsuccessful. The clutch size varies from one to three eggs, but two is typical. Eggs are creamy in colour with purple splotches.

Deep cup nest of the great reed-warbler. A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too ...
The breeding season is from July to December, and one or two broods are raised. Dusky robins are cooperative breeders, where two or three, presumably male, adult robins can look after a nest by feeding the female who is incubating the eggs. [2]
Eggs are laid on consecutive days with incubation only beginning once the final egg has been laid. Incubation is carried out by the female alone. [8] Incubation lasts between 16 and 18 days, after which chicks fledge around 13 to 15 days after hatching. The chicks remain dependent upon the parents for up to 42 days after hatching. [5]
South Island robins have a very good memory of their storage sites; a male was observed to empty as many as five consecutive caches before returning the stores to his mate during incubation. [14] The birds have demonstrated an ability to differentiate and prioritise caches of varying sizes, up to 12 total items, without any training, which ...
