Bruce M. Beehler is an ornithologist, naturalist, conservationist, author, and lecturer. He is a research associate in the division of birds at the Smithsonian National Museum of Natural History. And, he has published eleven books about nature. His new one is: North on the Wing: Travels with the Songbird Migration of Spring. Besides bringing a focus on our environment, it may inspire some special excursions of our own–in our back yard, our state, or perhaps a partial journey such as Bruce undertook following the spring migration.
