The same nest site may be reused in subsequent years. [32] [41] An old anecdotal record of these birds laying their eggs in the nests of Turdoides babblers has not been supported by later observers. [42] Laboratory studies have demonstrated cyclic changes in the melanin pigmentation of the tissue surrounding the testes. The dark pigmentation is ...
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 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 nest is built from dry grass by the female only, and is placed some 10 to 20 cm up at the heart of a grass tuft. [7] Usually three eggs are laid and these are incubated by the female only. The cream-coloured eggs, measuring 20 x 14 mm, are blotched with brown and purple around the thicker end. The chicks are reared by both parents.

The flame robin (Petroica phoenicea) is a small passerine bird native to Australia. It is a moderately common resident of the coolest parts of south-eastern Australia, including Tasmania. Like the other two red-breasted Petroica robins—the scarlet robin and the red-capped robin—it is often simply called the robin redbreast.
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 ...
It uses the prickly lawyer vine (Calamus muelleri) as nesting material and as a nest site. [8] The nest may be anywhere up to 10 m (30 ft) above the ground, though often much lower. Breeding season is July to December with one, or sometimes two, broods. A clutch of 2 oval eggs, measuring 20 by 15 millimetres (0.79 in × 0.59 in), is laid.
