Natural Selection: A Natural History of Nest Building/A Social History of Egg Collecting

From the publisher:

'I discovered that if I held a falcon egg close to my mouth and made soft clucking noises, a chick that was ready to hatch would call back.'

— Helen Macdonald, On Nests and Eggs

Natural Selection is divided into two parts, A Natural History of Nest Building and A Social History of Egg Collecting, and includes new essays by Darian Leader and Helen Macdonald.
