Building castles in the air

The common bird's nest is a miracle of engineering and design,
involving everything from spider's egg silk to feathers. Simon
Hadlington reports

Of all the great architects of the animal kingdom - beavers with their
dams, termites with labyrinthine mounds, wasps with papery nests -
perhaps the most prominent are the birds. Each spring, millions of
nests are constructed, using a vast array of materials, natural and
man-made. Most are disposable - they are used for one season only - and
yet they can be remarkably elaborate.
But despite their ubiquity, birds' nests have received surprisingly
little attention from naturalists. Dr Mike Hansell, a biologist from
the University of Glasgow, is trying to put that right. For many years,
he has had an interest in the behaviour of animals that build
structures, and in the early 1980s he turned his attention to birds'
nests.
