In the new book “White Feathers: The Nesting Lives of Tree Swallows,” celebrated Maine author and scientist Bernd Heinrich again unveils just how surprising and complex nature can be. The book “White Feathers,” released in February, follows Heinrich over the course of 9 years as he closely observes tree swallows during spring nesting season at his home in Maine. Throughout this long-term study, the experienced biologist is continually amazed by the birds’ abilities and behaviors. And though he starts his study of tree swallows with one question — Why do the swallows line their nest with rare white feathers? — he is soon puzzling about more of the birds’ complicated lives.
