Steel-green amazilia, red-rumped cacique, rufous-naped spinetail: enigmatic names familiar only to ornithologists. This book is about the nests of these and many other bird species, the strange, incredibly delicate balls and wickerwork, filigreed together from grass, clay, leaves and a multitude of other materials, that birds build to lay their eggs, brood and raise their young. With her pictures, Karen Weinert unites the perspectives of artistic and scientific observation.
