Want to get kids acquainted with North American birds? Look up my book "The Wonder of Wings". It has color illustrations of 24 species, and a rhyming poem to go with each, plus a few other poems about birds. I feel the rhymes will help kids remember facts they have read.
I also have a coffee table book of 256 nature photos (scenic landscapes, flowers, birds, insects, etc.) combined with captions that are either descriptive or imaginative, to enhance the impact of the photos. This book, titled "Expressions of Nature Through Photography and Words" , can be enjoyed by both children and adults.
