Weavers

There are 16 species of Weavers in South Africa.  They are seed-eating birds that are very common and weave complex nests.  The weavers are gregarious birds often breeding in colonies. Male birds weave elaborate nests as a display to attract a mate.  Females select the nest built by the best weavers. They first secure grass strips to a limb in loops using their beaks and feet to tie a half-hitch knot and weave additional strips through the loops.  Nests vary in size and shape hung from limbs and may include 1000 strips of grass.
