This one I like a lot. The illustrations are clear and the text is easy to understand. It does go that extra step to show what bird eggs and nests look like for the different species of bird. That being said, it is really hard to see most bird nest and eggs. Birds are naturally secretive about their nests so the best time to see them is in the fall when they are abandoned and the leaves have fallen.
I would start with Feathers for Lunch and if you child is super interested in birds, then this is a good next step.
