All this week I will be posting about field guides and, in particular, about Roger Tory Peterson and the new Peterson Field Guide to Birds of North America. I was a part of the team of people who worked on the new Peterson. More on that tomorrow...
I've asked this question before, but with all the new field guides that have appeared on the birding scene in the past year, it bears repeating.
What is YOUR favorite field guide/guides? And why?
