Rare Birds of North America by Steve N. G. Howell, Ian Lewington, and Will Russell. 2014. Princeton University Press, Princeton, NJ, USA. xviii þ 428 pp., 275 color plates. $35 (hardcover). ISBN 978-0-691-11796-6. Last winter I saw a Pinkfooted Goose (Anser brachyrhynchus) at a small lake not far from my home. This is a species I have seen many times, including flocks of thousands annually during much of my childhood. And yet I went out of my way to see this one because it was a bird I had never seen in Connecticut, where I now live. I’m neither a big chaser of rare species nor a very serious lister, but—like many in the field—I was a birder before I became an ornithologist, and the allure of the vagrant is hard to shake. For those of us who live in North America, Howell, Lewington, and Russell have provided a wonderfully detailed compendium of information on those species that have traditionally been relegated to the final pages of a field guide. Readers of this book will learn that the first widely accepted Pink-footed Goose record comes from Newfoundland in 1990, but that they are now found annually in the Northeast. They will also learn about an early Delaware record, long considered an escapee (though perhaps not, given the recent pattern of sightings); that the North American increase parallels rapid growth of the population in Europe; and that other Eurasian geese are also becoming more common on the left side of the Atlantic. The book is far more than a well-written compilation of rare records, however. Throughout, there is scholarly attention to detail, with careful definition of terms and exhaustive information about each spec i e s . In add i t i on to summarizing the records, every species account includes a concise commentary that provides context for the observed pattern and informed speculation about the underlying causes. Identification is also covered, with a greater emphasis on how to distinguish each rarity from simi la r North Amer ican species than one would find in a typical field guide. Even family monographs tend to gloss over the finer points of identification when species are unlikely to co-occur, making this information invaluable for those looking to find their own rarities or to evaluate the identifications of others. And for those who do not make annual trips to spend migration in the remoter parts of the Bering Sea or dream about finding an elaenia in the backyard, the identification sections offer much to help sharpen one’s birding skills.
