Frog Song
K-Gr 4-Guiberson has carefully chosen and researched 11 varieties of frogs whose habitats are scattered across six continents. In the spare text, she provides a transliteration of each species' song and describes how its young are incubated and hatched. For example, the male Darwin's frog scoops his tadpoles into his mouth and-after seven weeks of incubation-spits out his little froglets. On a spread at the end, the author notes where each frog can be found, its size, and an interesting fact or two. Each of Spirin's exquisitely detailed, larger-than-life illustrations, created with tempera, watercolor, and pencil, provides a two-page close-up of a species in its native habitat, with a large, pale-hued area set aside to house the large-print text. There is just enough information to interest older children who can read the book themselves, but the realistic pictures and fascinating facts can be shared one-on-one with younger children as well. A thought-provoking author's note mentions species-endangering changes in the environment caused by pollution, global warming, and paving of natural pathways. "A frog song is a celebration of clean water, plants, and insects to eat," Guiberson cautions. A bibliography and list of outstanding informational websites are appended to this beautifully presented nature lesson.-Susan Scheps, formerly at Shaker Heights Public Library, OHα(c) Copyright 2011.
