highly recommended new bird identification book

I recently received my new copy of the Peterson Guide to Bird Identification - In 12 Steps, by Steve N.G. Howell and Brian Sullivan.  There are a number of books that take one from the beginning steps of birding to the "next level" of advancing knowledge.  This book is different from many - the depth of coverage and sound advice address many topics more fully than some other superficially-similar books. The two co-authors have impeccable ornithological credentials, and they've put their years of experience to good use here. It is an ideal choice for a friend who has started birding and is ready to learn more. It's also valuable for experienced birders, providing new ways of looking at old challenges in identification. I recommend this book.

Chapters on plumage and songs/calls are especially good.

 Here are two reviews:

next new species for the Wisconsin state list?

Keep your "eyes peeled", in flocks of geese this spring, for a Pink-footed Goose. Increasingly found as a vagrant in eastern North America, here are some key points to identifying this species.

(Remember to look carefully among white-fronted geese; it is similar).
