Lita Judge (Flash Point/Roaring Brook, March 13, 2012)(ages 6-9). This elegant and amply illustrated forty-eight page picture book presents an introduction to the myriad ways in which birds (avian dinosaurs) communicate: vocalizing, strutting, fighting, etc. Drawings are realistic and the text spare yet informative. An afterword provides additional context on birds both familiar and unfamiliar.
A fascinating look at the natural world -- and I keep thinking it would be excellent paired with Diana Hutts Aston's AN EGG IS QUIET. Lita did a Writers and Illustrators and Dinosaurs post for me a couple months ago, and she is also the author of BORN TO BE GIANTS: HOW BABY DINOSAURS GREW TO RULE THE WORLD.
