San Francisco photographer Sharon Beals is here to remind us just how beautiful birds' homes can be. She describes her fascination with the creations like this:
"Bird nests, even without knowing which birds constructed them, seem hardly possible. Creations of spider’s web, caterpillar cocoon, plant down, mud, found modern objects, human and animal hair, mosses, lichen, feathers and down, sticks and twigs—all are woven with beak and claw into a bird's best effort to protect their next generation."
In an homage to avian builders, Beals traveled to a variety of museums to photograph their bird nest exhibits for her book Nests: Fifty Nests and the Birds that Built Them. Beals' Flickr gallery of the images is certainly worth a long visit.
