The Warbler Guide: downloadable 'quick finders'

Princeton University Press, publishers of the outstanding new guide to North American warblers, The Warbler Guide, have made available some helpful charts summarising visual identification features of the species - just in time for fall migration! These images appear at the start of the book. The files can be donwloaded from the Princeton University Press blog in .PDF and .JPG format.

I will no doubt be reviewing this book as soon as I can get hold of a copy.
