Students will enter the world of scientists as they uncover the secrets behind birds' brains, the most underappreciated of birds' senses, the way frigate birds fly non-stop, how mama bears protect their cubs, and what grunts and bellows mean for pigs and alligators. Primary sources, including interviews with scientists; full-color original and stock photos; an engaging and approachable writing style that simplifies complicated scientific principles; and a hands-on activity make these informational texts a valuable addition to any library.
