One of the Best Bird Books Ever.
Reviewed in the United States on August 17, 2018
I obtained the hardbound version of the book our Vertebrate Zoology Natural History class used in college. It is excellent in the ease of identifying the birds. It has COLOR pictures, provides differentiation points between similar species as well as the immature birds vs adults, the bird songs sonograms, ranges, flight patterns, etc. The book covers the entire US and some of Canada and Mexico, but does not segregate by East Coast/Central/West Coast - which means that unless one does a lot of continental traveling a lot of the info will not be useful. There is a newer edition (with blue cover) than the edition I used in college - I have both.
