A successful West Nile virus vaccine has been administered to six 3-5 week old American robins. A DNA vaccine injected intramuscularly resulted in a 400-fold decrease in average viral load that would likely make robins noninfectious and unable to spread disease. An oral bait is the preferred method of distribution of the vaccine as it would be ...
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 robin is diurnal, although it has been reported to be active hunting insects on moonlit nights or near artificial light at night. [18] Well known to British and Irish gardeners, it is relatively unafraid of people and drawn to human activities involving the digging of soil, in order to look out for earthworms and other food freshly turned up.
The nest of the long-tailed tit, Aegithalos caudatus, is constructed from four materials – lichen, feathers, spider egg cocoons and moss, over 6000 pieces in all for a typical nest. The nest is a flexible sac with a small, round entrance on top, suspended low in a gorse or bramble bush. The structural stability of the nest is provided by a ...
Black robins live in low-altitude scrub forest remnants. They are entirely insectivorous, feeding on the forest floor or on low branches, and preferring to nest in hollow trees and tree stumps. To shelter from the strong winds and rough seas around the islands, they frequent the lower branches of the forest, or in flat areas with deep litter ...
The flame robin, Petroica phoenicea, 1931 by E. E. Gostelow The largest of the red robins, the flame robin is 12–14 cm (4.7–5.5 in) long. It has a more slender build than other members of the genus Petroica, with relatively long wings and neck and small head. [12]
Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 13.5 cm (5.3 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. [3] The male has a distinctive white forehead spot and pink breast, with grey-black upperparts, wings and tail. The belly is white.
The eastern yellow robin occupies a wide range of habitats: heaths, mallee, acacia scrub, woodlands, and sclerophyll forests, but is most often found in damper places or near water. Like all Australian robins, the eastern yellow robin tends to inhabit fairly dark, shaded locations, and is a perch and pounce hunter, typically from a tree trunk ...
