Books

Cat Wars paints a revealing picture of a complex global problem—and proposes solutions that foresee a time when wildlife and humans are no longer vulnerable to the impacts of free-ranging cats.

“Very few people enjoy thinking about the calamitous problem of free-roaming cats and biodiversity, and even fewer dare to talk about it openly. Marra and Santella’s book is therefore doubly welcome. It’s not only important reading for anyone who cares about nature. With its engaging story-telling, its calmly scientific approach, and its compassionate handling of a highly fraught issue, this is also a book that a person might actually read for pleasure.”Jonathan Franzen

In Birds of Two Worlds Russell Greenberg and Peter Marra bring together the world’s experts on avian migration to discuss its ecology and evolution. The contributors move the discussion of migration to a global stage, looking at all avian migration systems and delving deeper into the evolutionary foundations of migratory behavior.
