"A Guide to the Nests, Eggs, and Nestlings of North American Birds" by Baicich and Harrison is a sorely needed reference to a subject familiar and interesting to both casual birdwatchers and serious ornithologists. Up to now, the standard reference was Hal Harrison's "Birds' Nests" (one for the eastern U.S., another for the west), Peterson Field Guides published in 1975. As the title indicates, these books feature photographs of nests (one picture per species), most with eggs. Many nests (and eggs) look alike, and these books are not especially helpful in identifying nests or their contents. While the Peterson Guide to eastern nests, for example, covered only 285 species, the Baicich and Harrison book covers 669 species nesting in North America.
Baicich and Harrison have created a book that is both practical and beautiful. The first 16 color plates portray dozens of nestling birds -- even the most un-anthropomorphic of us will find many of them cute! A number of the plates show the distinctive "gapes" or open mouths of the nestlings. The rest of the nearly 50 plates are eggs, carefully rendered to show subtle characteristics in color and pattern and displayed to show relative size. For some species, more than one egg is shown to demonstrate variety. These plates are so well done that the varying degrees of gloss are captured, an extremely useful detail. Opposite each plate is a short description of the eggs of the family, a key to the species, and the page number of the text.
The text section contains additional black-and-white sketches of nestlings and nests of many species. Text is concise but thorough, covering breeding habitat, a description of the nest including materials and placement, dates of the breeding season, a description of the eggs including measurements, details on the incubation and nestling periods, and a description of the nestling.
The introductory material is worthwhile as well. A short section on the legal and ethical considerations of studying nesting birds is wisely included. Discussions on each of the items included in the text are presented. These go beyond a simple definition and into some detail. For instance, the paragraphs on eggshell color tell us that newly laid eggs can briefly have a pinkish hue; the types of pigments that color eggshells; that while there might be variation within the species, each female usually lays consistently-colored eggs; and what causes abnormally colored eggs. The mechanics of hatching and the types of nestlings and their anatomy are also covered. Next, there is fine text on responsible nest-finding techniques and an overview of nest monitoring and recording schemes. Finally, there are three keys: Nests, Eggs, and Young nestlings and chicks.
As a professional ornithologist, I rarely cracked open my Peterson Guide to nests. However, I often browse "A Guide to the Nests, Eggs, and Nestlings of North American Birds," even when I am not in need of an immediate reference. This is a book with a place on any bird lover's shelf.
