In 1975, my dad gave me Peterson's Field Guide to Western Birds (copyright 1961).? It got me through college Ornithology, and has been a constant companion for decades.? Today, I bought the 2016 edition of Sibley Birds West.? I feel a bit like a traitor, but am willing to try something new!? Heading to Yellowstone on Saturday, taking both the new Sibley and the old Peterson stand by.? :-)
