Oology is the branch of ornithology that includes the study of eggs. While that field of study may seem prosaic, the simple form of an egg hides incredible biological and cultural complexity. Award-winning German author and illustrator Teckentrup (Bee, 2016) explains fascinating facts about eggs' colors, shapes, functions, and sizes across countless avian species. While the majority of the book is comprised of beautifully soft-hued illustrations and brief blocks of text explaining bird nests and the eggs that they contain, all oviparous animals, including insects, fish, and reptiles, get at least a mention. Biological diversity is the unifying theme, as Teckentrup explains the adaptive reasons that eggs differ from species to species. Additionally, humans' reverence for eggs as objects of religious, mythological, and artistic significance is described. Teckentrup's latest book, particularly its gently muted illustrations, succeeds at a very difficult task couraging young readers to find beauty and profundity in some of nature's most seemingly ordinary objects.

This part-aesthetic, part-scientific consideration of eggs (mainly from birds but also those of insects, reptiles, fish, and amphibians) includes musings on the form and structure of eggs, the nests built to shelter them, and the role of eggs in human culture. The spare illustrations use a gorgeous mellow palette to represent the varieties of eggs and their producers.

Gr 2-6In this European import, gorgeous, earth-tone illustrations and fact-packed text introduce one of nature's most perfectly designed wonders: "An egg is fragile and strong at the same timeordinary and extraordinary." Handsome spreads briefly cover an array of topics from the biological to the more philosophical. The bulk of the volume focuses on birds, describing the variety in shape and color of the eggs of different species, the anatomy of a chicken egg and embryonic development, and the largest egg (Madagascar's now-extinct elephant bird's, at about 13.39 inches) and the smallest egg (a hummingbird's, at .39 inches). A section highlighting the construction of various nests features the female oriole's tightly woven pouch nest, the mud mounds of the flamingo, the woodpecker's tree cavity hideaway, the guillemot's dangerous cliff nest (should the eggs be knocked over, their "highly adapted" conical shape causes them to spin in a tight circle rather than fall off the edge), and more. The rest of the book dips into insect eggs, frog spawn, reptiles, trout eggs, and the platypus before switching gears to discuss the role of the egg in art, religion, and mythology as well as egg-related customs and symbolism. VERDICT Filled with fascinating tidbits and striking visuals, this title, with its miscellany-style format, is more appropriate for browsing and musing than report writing.Joy Fleishhacker, Pikes Peak Library District, Colorado Springs
