Weaver bird nests hanging from an acacia tree in Samburu National Reserve, Kenya

Among the 350 species of birds found here at the Samburu National Reserve, one of the most industrious is the weaver bird. This species is so named for its intricately constructed nests that are woven from twigs, grasses and leaves. You can see the birds’ handiwork on this acacia tree, where nests hang like ornaments. Some weaver birds build elaborate nests that house hundreds of birds, with separate chambers for each pair, creating a natural apartment complex in the treetops.
