The male bird, the master craftsman who builds a nest that can last a full season – upto 3 months for its usage and then abandoned for other birds like silverbill etc which use the abandoned nests. The whole activity of building the nests is to woo a mate. The nests are made of blades of grass that are bought and weaved together to make a looped attachment to a branch or a hanging cable, different chambers and a tube shaped entrance.  The weaver birds are also known to knot together the grass blades using their beak…at times even doing a reverse knot. To build a nest the bird makes on an average anything upwards of 500 trips.
