The sociable weaver is a fascinating bird that I discovered in Namibia’s Etosha National Park. They spend years building huge nests in trees and continue to build on them, until they eventually fall apart or break the tree limbs. They are the largest nests built by any bird. If you are a bit of a nature nerd, watch this video about the sociable weaver. If you’re not, at least watch the first 30 seconds to see a massive nest!
