Doris L. Mueller's The Best Nest - is SUPERB!!! Another Sylvan Dell book that makes top marks with me!! (And it isn't just because I am a bird lover either!!) Ever wondered why birds build their nests differently - well this book explains it! It is told in story format, so it's non-fiction learning with fiction story - I love that. The illustrations, by Sherry Neidigh, are beautiful - eye-catching pictures of birds and nests. AND the best part of a Sylvan Dell book?? All the parent/teacher helps in the back of the book - oh yes, and their magnificent website - see, I could just go on and on.
