When preening, a bird (such as this red lory) draws individual feathers through its beak, realigning and re-interlocking the barbules.. Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check.
Allowing particulates to accumulate on feathers also creates the need for cleaning which can put fragile feathers at risk for physical damage. [15] In addition, particulates can cause the relative humidity around the feather to rise. This rise in humidity and the resulting addition of moisture can accelerate the deterioration of the feather. [2]
[27] [29] The nest cavity is 25–35 cm (9.8–13.8 in) deep with an entrance hole 5–6 cm (2.0–2.4 in) wide. It is excavated by both sexes, the male doing most of the chiselling. [6] As with other woodpeckers, the hole is unlined, although wood chips from the excavation may cover the base of the cavity. [30] Egg
For example, bird specimens that have been badly damaged by pests may be repaired with a mixture of synthetic fabrics and wheat starch. This mixture is used to infill areas of loss and feathers are replaced where possible with a wheat starch paste adhesive. In addition to infilling, taxidermy specimens may require structural repairs.
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 ...
A so-called "cathedral" mound produced by a termite colony. Structures built by non-human animals, often called animal architecture, [1] are common in many species. Examples of animal structures include termite mounds, ant hills, wasp and beehives, burrow complexes, beaver dams, elaborate nests of birds, and webs of spiders.

Male and Female house sparrows dust bathing. Birds crouch close to the ground while taking a dust bath, vigorously wriggling their bodies and flapping their wings.
The nest hole takes about two or three weeks to create, and normally measures 12 to 15 cm wide and about 20 to 30 cm deep. [20] A female will typically lay 4–5 white eggs, but can lay up to 7. During waking hours, both birds will incubate, or warm the eggs for 15 minute periods, taking turns in alternating shifts. At night, the male ...
