The nesting season is almost year round, from December to April and July to October. The birds build large colonial nests of mud. They consist of many pot-like nests fused together. Entrance to each nest is via a short tube. [3] Flocks of streak-throated sparrows appear to be attached to specific locations.
The birds are best known for building massive nest mounds of decaying vegetation, which the male attends, adding or removing litter to regulate the internal heat while the eggs develop. However, some bury their eggs in other ways; there are burrow-nesters which use geothermal heat, and others which simply rely on the heat of the sun warming the ...
Golden eagles maintain home ranges or territories that may be as large as 200 km 2 (77 sq mi). They build large nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life.
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 ...
Sociable weavers construct permanent nests on trees and other tall objects. These nests are amongst the largest built by any bird, and are large enough to house over 100 pairs of birds, [10] containing several generations at a time. The nests are highly structured and provide birds with a more advantageous temperature relative to the outside.
The Bird Island Nature Reserve in Lambert's Bay, Western Cape, South Africa. A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony.
It builds a very large nest for a smallish bird, weaving thorny twigs into a cylinder that is usually up to 110 cm (43 in) high and 40 cm (16 in) wide, though nests double this size are known. It has an entrance hole near the top leading through a winding tunnel to the nest chamber; the chamber is lined with plant fibers, feathers, and other ...
Other birds often built their own nests on top of Weaver nest sites. [4] Some birds build nests in trees, some (such as eagles, vultures, and many seabirds) will build them on rocky ledges, and others nest on the ground or in burrows. [3] Each species has a characteristic nest style, but few are particular about where they build their nests.
