"You may not have a yard, but you do have the sky. Look up!" Busy pages and cartoon-like conversation bubbles encourage reluctant naturalists to give birding a chance by emphasizing how easy it is to do anywhere, from the window of a city apartment building to suburban backyards and beyond. Bird-watching requires no expertise and few supplies, but close observation-watching and listening-is key. There's a wealth of information about bird appearance and behavior packed into this slim, highly visual volume in which author/illustrator Annette LeBlanc Cate shares her enthusiasm for and knowledge about birding, along with her silly sense of humor, with young readers. (Ages 7-10)
