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.
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.
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.
Female birds are able to produce more of a certain gender of birds that are more likely to survive under extreme conditions. In birds, the females' egg determines the gender of the offspring, not the male's sperm. In zebra finches, a study showed the effect of food on gender ratio production. For females, egg production is a metabolically ...
Precocial birds find their own food, sometimes with help or instruction from their parents. Examples of precocial birds include the domestic chicken, many species of ducks and geese, waders, rails, and the hoatzin. Precocial birds can provide protein-rich eggs and thus their young hatch in the fledgling stage – able to protect themselves from ...
The birds spend the nights on the sandbars and in shallow water of the Wisconsin River and fly out to forage in fields during day. Most years the river freezes or snow covers the fields in ...
A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
