Watching a bird building a nest can be fascinating to watch. We came upon this Red-Headed Weaver on a safari in South Africa that was in the process of doing exactly that. The nest that red-headed weavers build is a bit different than other birds in South Africa. They are one of the few birds that build their nests that are entirely made of twigs and, when finished, the nest resembles a small tight ball. The nest is built that way to protects them from predators. Being that they are built during mating season, the nest probably also provides some privacy while they create offspring. Watching this particular bird building his nest, it easy to see that weaver is a perfect name as their construction is performed just as a human weaver might do it.
