Habitat-selection hypothesis. Habitat selection hypothesis is one of several hypotheses that attempt to explain the mechanisms of brood parasite host selection in cuckoos. Cuckoos are not the only brood parasites, however the behavior is more rare in other groups of birds, including ducks, weavers, and cowbirds. [1]
The bird's habitat is open grassland and undisturbed cultivation, with plants tall enough for cover. Males and females do not differ markedly in habitat selection. [7] It has a stately slow walk, and tends to run when disturbed rather than fly. It is gregarious, especially in winter.
Ideal free distribution. In ecology, an ideal free distribution (IFD) is a theoretical way in which a population ' s individuals distribute themselves among several patches of resources within their environment, in order to minimize resource competition and maximize fitness. [1][2] The theory states that the number of individual animals that ...

Brood parasitism is a subclass of parasitism and phenomenon and behavioural pattern of animals that rely on others to raise their young.
Basic bird counts are a good way to estimate population size, detect changes in population size or species diversity, and determine the cause of the changes if environmental or habitat data is collected as well. Basic bird counts can be completed fairly easily and inexpensively, and they provide general information about the status of a bird ...
Pangalloanserae (fowl) Neoaves. Synonyms. Neornithes Gadow, 1883. Birds are a group of warm-blooded vertebrates constituting the class Aves (/ ˈeɪviːz /), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
The sociable weaver (Philetairus socius) is a species of bird in the weaver family, endemic to Southern Africa. [2] It is the only species in its genus Philetairus. It is found in South Africa, Namibia, and Botswana, [1] but its range is centered within the Northern Cape Province of South Africa. [3] The species builds large, compound ...
Their breeding habitat is shrubby fields, often wet, in southern Canada, the northeastern United States, [6] and the midwestern United States. [7] In 2020, the Central Kentucky Audubon Society discovered that a population of Henslow's sparrows near a winery only needed 5 acres of grassy habitat to successfully breed (previous research had suggested at least 20 to 75 acres were necessary).
