The natural and wild environments of our national parks offer the unsurpassed protection and diverse ecosystems that birds need to thrive. And that makes our parks equally great places for you to see birds. This week the Traveler's Lynn Riddick talks to birding expert Nicholas Lund of Maine Audubon, who believes that whether you consider yourself a full-fledged birder or just someone who simply likes birds, when it comes to our national parks, there's always a bird in the air, in a tree or along the water's edge to see, hear, and learn about.
