Bird nests are wonderfully curious objects. Twigs, grass, moss, feathers and leaves woven together with secret intent. Every bird nest tells a unique story known only by the bird who created it, and by the nestlings it shelters and protects. This piece celebrates the intelligence, mystery and beauty of the nest-building process.

Birds use nests to shield their eggs and nestlings from predators and bad weather. Birds will cleverly camouflage, hide or build their nests in hard to reach places to keep predators at bay. As important as nests are for bird survival, very little is known about the mysteries of the nest-building process. Instinct surely plays a role, but how much or how little? Bird nests are 3D extensions of a bird's mind. In the center of this piece is a large bird eye, constantly on alert, always aware of its surroundings. As I built this rotating assemblage, my mind was full of questions:


  • How do birds choose their nesting materials? By shape, color, density, size, pliability?

  • Why do some species of birds glue their nests together with saliva or mud while others dig or weave?

  • Is all bird saliva similar in stickiness?

  • Is the saliva of birds that glue their nests together different from the saliva of birds that weave their nests?

  • Do birds try to use the same materials that were used in the nest they were raised in?

  • Do nest-building skills improve over time? Does practice make perfect?

  • Do birds learn building techniques from others in their flock?

  • If nest-building happens on a windy day, is construction put on hold?

  • Do birds choose their mates based on the quality and size of their nests?

  • Do birds search for materials in their established territory or do they establish territory based on available nest-building materials?

Birds will flock together to migrate, search for food and stay safe from predators. Murmuration, flying together in quick movements and patterns that seem connected and one-minded, is a phenomenon of nature that amazes and delights all who are lucky enough to see it. This piece was created to celebrate the mystery of the super-organism that is created when a large flock of birds travel together across the sky.
