INTELLIGENTLY CONSTRUCTED NESTS: The social weaver is a bird - TopicsExpress



          

INTELLIGENTLY CONSTRUCTED NESTS: The social weaver is a bird that builds colonies of as many as 500 individuals. Their nests weigh a ton, literally. Biologists suggest these are the largest vertebrate societies centered around a single structure aside from human-built dwellings and complexes. These nests are not just structural spectacles to behold, but they meet mechanical engineering requirements with thermal protection to keep the inner chambers at a comfortable 70 to 75 degrees F. while outside temps are well below freezing. These nests typically provide 100 separate chambers, all partitioned with separate entrances on the bottom surface of the nest. My message to beavers would be, Eat your heart out.
