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 ...
Almost all species of birds moult at least annually, usually after the breeding season, known as the pre-basic moult.This resulting covering of feathers, which will last either until the next breeding season or until the next annual moult, is known as the basic plumage.
Clearing of woodlands causes declines in numbers of neotropical migrants while favoring short-distance migrants and permanent residents. [36] This benefits the American goldfinch both because it is a short-distance migrant and because the created open areas are the preferred environment of the bird, where weeds thrive which produce the primary ...
The molt occurs in two different patterns which coincide with the blackness of the upperparts quite well. Here too is a broad zone of intergradation. Pacific birds molt after breeding, and females shed a few body feathers before breeding too. Juvenile males shed more remiges than females when molting into
The mourning dove (Zenaida macroura) is a member of the dove family, Columbidae.The bird is also known as the American mourning dove, the rain dove, the chueybird, colloquially as the turtle dove, and it was once known as the Carolina pigeon and Carolina turtledove. [2]
In North America, northern populations have developed a migration pattern, vacating much of Canada in winter. [95] Birds in the east of the country move southwards, and those from farther west winter in the southwest of the US.
In most temperate species, males will undergo molting between seasons, so that non-breeding males will somewhat resemble the females of their species. These species, such as the indigo bunting, will exhibit a complex molt cycle going through four different stages of plumage coverage within their first year of life. From spring to summer, birds ...
Forced molting typically involves the removal of food and/or water from poultry for an extended period of time to reinvigorate egg-laying. Forced molting, sometimes known as induced molting, is the practice by some poultry industries of artificially provoking a flock to molt simultaneously, typically by withdrawing food for 7–14 days and sometimes also withdrawing water for an extended period.
