It is one of the first North American bird species to lay eggs, and normally has two to three broods per breeding season, which lasts from April to July. [ 13 ] The nest is most commonly located 1.5–4.5 m (4.9–14.8 ft) above the ground in a dense bush or in a fork between two tree branches, and is built by the female alone.
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 Cape robin-chat occurs from South Sudan (mainly Imatong Mts, above 1,600 m) southwards to Uganda, the DRC (1,800 m – 3,475 m), Kenya, Tanzania, Zambia (above 1,800 m), Malawi (where common above 1,500 m), Zimbabwe, Namibia, South Africa, Eswatini and Lesotho. It is a mainly resident breeder in eastern and southern Africa, though some ...
The mourning dove is a medium-sized, slender dove approximately 31 cm (12 in) in length. Mourning doves weigh 112–170 g (4.0–6.0 oz), usually closer to 128 g (4.5 oz). [ 26 ] The mourning dove has a wingspan of 37–45 cm. [ 27 ] The elliptical wings are broad, and the head is rounded.
Two or three clutches of five or six eggs are laid throughout the breeding season, which commences in March in Britain and Ireland. The eggs are a cream, buff or white speckled or blotched with reddish-brown colour, often more heavily so at the larger end. [41] When juvenile birds fly from the nests, their colouration is entirely mottled brown.
These eggs are incubated by the female, [14] usually after the second-to-last egg is laid, [54] for 11 to 20 days, [53] although most hatch after 14 to 15 days. About 88% of nests produce at least one nestling, but this can be lowered by poor weather and a younger breeding female. [14] The eggs generally hatch in the order they were laid.
The eggs are a light blue or greenish color and speckled with dots. [15] The female lays three to five eggs, and she incubates them for nearly two weeks. Once the eggs are hatched, both the male and female will feed the chicks. [33] The birds aggressively defend their nests and surrounding areas against other birds and animals. [33]
The blue jay is a noisy, bold, and aggressive passerine. It is a moderately slow flier (roughly 32–40 km/h or 20–25 mph) when unprovoked. [27] It flies with body and tail held level, with slow wing beats. Its slow flying speeds make this species easy prey for hawks and owls when it flies in open areas.
