Wing clipping is the process of trimming a bird's primary wing feathers or remiges so that it is not fully flight-capable, until it moults, sheds the cut feathers, and grows new ones. This procedure is usually carried out by avian veterinarians, breeders, or the bird's owners, and primarily on pet birds like parrots.
The young birds are at risk of disease and may have a lower survival rate depending on environmental conditions (Grindstaff 2003). [25] Carotenoids in egg yolk are responsible for the red or yellow color. They protect the underlying fetus's tissues from the free radicals in the environment.
In birds, this parental care system is generally attributed to the ability of male birds to engage in most parental behaviours, with the exception of egg-laying. Due to their endothermy and small size at birth, there is a huge pressure for infant birds to grow up quickly to prevent energy loss.
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.

Altricial birds are less able to contribute nutrients in the pre-natal stage; their eggs are smaller and their young are still in need of much attention and protection from predators. This may be related to r/K selection; however, this association fails in some cases. [18] In birds, altricial young usually grow faster than precocial young.
They are very good recyclers because often reuse the same nest year after year, adding new materials to repair and reinforce it as needed. Tawny frogmouths pair up for life. Females lay 1-3 eggs ...
