In this short book, celebrated biologist Marty Crump leads readers on a worldwide field trip in search of frogs. Each chapter of Frog Day covers a single frog during a single hour, highlighting how twenty-four different species spend their time. Our day begins at midnight in Indonesia, with the rustle of leaves above. It’s not a bird, but Wallace’s flying frog, using its webbed feet and emerald-green skin flaps to glide through the forest canopy. In the early hours of the morning, we hear a horned marsupial frog “bopping” and a wood frog “quacking” to attract mates. At six o’clock in the morning, beneath a streetlight in Honolulu, we meet a corpulent, invasive cane toad slurping insects & sometimes snakes, lizards, turtles, birds, and mice. At noon, we watch parenting in action as an African bullfrog bulldozes a path through the mud to free his tadpoles from a drying pond. At dusk, in a Peruvian rain forest, we observe “the ultimate odd couple”–a hairy tarantula and what looks like a tiny amphibian pet taking shelter in the spider’s burrow. Other frogs make a tasty meal for this tarantula, but the dotted humming frog is a friend, eating the ants that might otherwise make a meal of the tarantula’s eggs. For each hour in our Frog Day, award-winning artist Tony Angell has depicted these scenes with his signature pen & ink illustrations. Working closely together to narrate and illustrate these unique moments in time, Crump and Angell have created an engaging read that is a perfect way to spend an hour or two–and a true gift for readers, amateur scientists, and all frog fans.
