The baya weaver is a weaverbird found across the Indian Subcontinent and Southeast Asia. Flocks of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging retort shaped nests woven from leaves. They are social creatures so they make colonies of nests.These nest colonies are usually found on thorny trees or palm fronds and the nests are often built near water or hanging over water where predators cannot reach easily. They are widespread and common within their range but are prone to local, seasonal movements mainly in response to rain and food availability
Male weaver birds construct their intricate nests during mating season, using them to attract prospective mates. Sometimes, after the male has completed the basic structure of the nest and a female has approved it, the female will help him to complete the nest. The males take about three weeks to construct the complete nest. The females inspect the nest and signal their acceptance of a male. Once a male and a female are paired, the male goes on to complete the nest by adding the entrance tunnel. Males are almost solely in charge of nest building, though their female partners may join in giving the finishing touches, particularly on the interiors. Females may modify the interiors or add blobs of mud. A study has found that nest location is more important than nest structure for the female when it selects the nest and mate. Females prefer nests high in trees, those over dry land, and those on thin branches. Males break down the nests if they are not preferred and occupied by the females. So that they can build a new green nest in its place and try to attract a female to that.
