Penguins are animals? Penguins have fur?

I have read thousands of books to my daughter. (3,144 different books to be precise.) I have reasonable expectations. If the book purports to be non-fiction it should be accurate. If the book is fiction then I expect the story to hold my interest.

This book, Frosty Friends from Priddy Books, is about animals from cold places.

At the risk of being pedantic, I have two problems with this book.

1. Penguins are not animals, they are birds (The book also includes a photograph of an Owl, also not an animal.)
2. Penguins, and all other birds, have feathers NOT fur

Is there any excuse for this sort of inaccuracy? None that I can think of.

Am I just being ridiculously picky? I don't think so. The publisher uses the tag line, "big ideas for little people". A big idea, especially one aimed at children, should not be one that gives inaccurate information.

So, I'll just keep on being pedantic until it is made illegal.
