The weaver birds, especially the male weaver birds are expert construction engineers who build their beautiful nests which is very strong, water proof, storm proof, with sufficient light inside the nest. No rain or heat or storm can damage the nest.
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.
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.
