Ethan Long. Abrams Appleseed, $7.95 (20p) ISBN 978-1-4197-1365-1

More than a dozen animals salute each other with rhyming exclamations in a typically quirky offering from Long. In facing single-page vignettes, the animals smile and wave at each other: “Chirp!” says a red bird, perched on its birdhouse. “Slurp!” responds a fuzzy anteater, its snout deep in an anthill. Elsewhere, a polar bear’s “Growl!” is met by a wolf’s “Howl,” and a crow’s “Caw!” by a bucking, bucktoothed donkey’s “Hee-haw!” Zoological accuracy isn’t exactly the point (Do yaks really say “yak”?), but this friendly chain of greetings and Long’s bright, spongy-edged digital illustrations create an infectious sense of good cheer. Up to age 2. (May)
