The Birds of Concord: A Study in Population Trends
Ludlow Griscom
Thoreau, over a century ago, and the great William Brewster and his friends of the Nuttall Ornithological Club after him, have been followed by more than a hundred students and countless amateurs in their loving study of the birds of the Concord and Sudbury river valleys in eastern Massachusetts. Meanwhile the effects of civilization on bird life have been many and various. Here is a book which tells the whole fascinating story for the nature lover and the ornithologist and which gives the scientific biologist a careful population study.
