Here are some of the most amazIng animal architects in the world. These animals have been building intricate structures since long before humans began constructing complex dwellings: • The beaver builds a den from twigs and mud often rerouting streams. • Compass termites build huge wedge mounds in order to regulate the temperature of the underground nest. • Many birds have intricate homes like the sociable weaver, swallows, the Montezum Oropendola and many others.
