Have You Heard the Nesting Bird? by Rita Gray
Bring on the Birds by Susan Stockdale
The first book has a great Q and A section at the end conducted between a bird and the questioner, called “A Word with the Bird.”
The second book places birds into simple (and rhyming) categories, concluding with a who’s who of the birds pictured earlier in the book.
This would be a great opportunity to listen to bird calls online! Children might enjoy trying to imitate the sounds.
