We must be careful what we say. No bird resumes its egg. Emily DickinsonAnd what a shame, as while birds are stunning in their plumage, the variety and beauty of the vessels from which they hatch are beguiling. The egg has been called nature s perfect container. And the variation on a theme is spectacular from the bold purple red hue of a Tinamou egg to the roughly surfaced greenish-blue Emu egg. Incubation varies as much as color from days to months as does the clutch size. All of these different egg types reflect ecological and evolutionary dynamics."The Book of Eggs" introduces readers to the eggs of 600 bird species. Bird eggs have inspired artists like Rosamond Purcell, and countless birders have considered them quarry. For scientists, these brilliant vessels lead to an array of interesting topics, from the patterns of egg coloration to how birds and their parasites recognize eggs. Particularly appealing is this book s use of The Field Museum s bird egg and nest [...] an introductory section, the work is organized taxonomically. Each entry, which focuses largely on North American birds, includes life-size photos, distribution maps, and drawings of the birds from which the eggs emerge. The text discusses bird behavior and the egg traits, inclusive of some evolutionary explanations for the variance of form. This is the first time the Field s egg collection has been photographed, and it is world renowned for its content. The book will also include portrayals and descriptions of the clutches, which can be a helpful tool in identifying species for birders.
