The sociable weavers. They build and share one enormous nest designed to keep them cool in the summer, warm in the winter and safe from raptures and predators. Some nests have been known to be a mind blowing near 100 years old. This equates to as many as, if not more than 10 generations of family. Working together, each family member has a specific job description as they age and amazingly they require almost no water at all making them one of the few species of animals who can withstand the harsh desert conditions. Together strong.
