Hear a chorus of songbirds in spring. Watch a parade of migrant raptors circle high above Hawk Mountain. See the gulls swoop for fish in Lake Nockamixon. Walk the same paths as America’s early ornithologists and you’ll come across many of the same species. Nearly half of all the bird species found in North America can be seen right here in Pennsylvania year 'round. From hawks and hummingbirds to warblers and woodpeckers, enjoy Pennsylvania’s bird population along our water trails, scenic drives, old-growth forests, lush wetlands, mountainous areas and lakes.
