Detailed explanation-1: -In the majority of nest-building species the female does most or all of the nest construction, in others both partners contribute; sometimes the male builds the nest and the hen lines it. In some polygynous species, however, the male does most or all of the nest building.

Detailed explanation-2: -The male weaver bird make beautifully woven nests. The female looks at all the nests and chooses the one that she likes the best and decides in which to lay her eggs.

Detailed explanation-3: -Bowerbirds (/ˈbaʊ. ərbɜːrd/) make up the bird family Ptilonorhynchidae. They are renowned for their unique courtship behaviour, where males build a structure and decorate it with sticks and brightly coloured objects in an attempt to attract a mate. The family has 27 species in eight genera.

Detailed explanation-4: -Stickleback nests therefore serve as receptacles for developing embryos and provide protection from water currents and the attentions of both con-and heterospecific predators (Potts, 1984).
