Birds make nests not to live in but lay eggs and start the next generation. Nests are of wide sizes and shapes, ordinary but practical and ornate type. But the nest of Baya Weaver bird is a work of great craftsmanship. It is made exclusively by male bird in the height of summers in India.
Finished Nest has two doors but there is a catch. When the nest reaches the stage when the vertical door is to start, male bird invites the female who inspects the work. If she likes it and agrees to move in for making a pair for eggs and chicks and next generation. If she reject it, the male is dejected and dismantles the entire work. It then begins to weave another nest.
It is said that Baya Weaver makes more than 500 trips to bring the grass stalks for nest building. The nests are made on the trees like acacia and other thorny trees which makes the entry of predators difficult. They are generally on the trees which are near the water bodies.
