The Weaver’s bill is typically robust and tough – ideal for crunching seeds and grains, but also well put to other ingenious use by these industrious birds.  Weaver birds are the architects of the bird world.  Neatness of construction and design varies widely among the different species of Weaver birds.  Some nests are simple and scruffy with a small tube and roundish shape, while other species build much more elaborate nests with strands of grass carefully interwoven to form a well-defined structure.  The main nest part is a hollow sphere, lined with nesting material, accessed through a long tube, which has a small entrance hole.  The nests are usually tough and well- secured so high winds do not blow them down.
