The larger American robin (Turdus migratorius) is a much larger bird named from its similar colouration to the European robin, but the two birds are not closely related, with the American robin instead belonging to the same genus as the common blackbird (T. merula), a species which occupies much of the same range as the European robin. The ...
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 markings are denser at the larger end of the egg, where they form an irregular cap. Some eggs are blotched with dark reddish-brown at the large end. They are about 0.76–0.84 inches (1.9–2.1 cm) long and 0.55–0.62 inches (1.4–1.6 cm) wide. [28] Three to four eggs is the usual clutch. [36]
When the female is ready, she lays about 3-5 eggs of greenish color, one egg per day, and incubates them for roughly 2 weeks. Once born, the young chicks are nurtured for a month, or 31 days, before they leave the nest and become independent. The robin does not mate for life and only finds a partner during the spring mating season.
There are usually two or three eggs and the incubation is done solely by the hen bird and lasts fourteen to fifteen days. Both parents feed the chicks, which leave the nest after about a fortnight but remain dependent on the adults for another six or seven weeks. The white-throated robin-chat is sometimes parasitised by the red-chested cuckoo. [6]
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.
The hooded robin (Melanodryas cucullata) is a small passerine bird native to Australia. Like many brightly coloured robins of the Petroicidae , it is sexually dimorphic ; the male bears a distinctive black-and-white plumage, while the female is a nondescript grey-brown.
The breeding season ranges from December to February in eastern Africa, September to January in Malawi, Zambia and Zimbabwe, and September to December in South Africa. The nest is made of plants, lichen and hair. The clutch size is two to three eggs. The eggs may be white, pale green or bluish, and have many spots. The female incubates the eggs ...
