Katmai's lake edges and marshes serve as nesting sites for tundra swans, ducks, loons, grebes, and that 20,000-mile annual commuter, the arctic tern. Sea birds abound along the coast, grouse and ptarmigan inhabit the uplands, and some 40 songbird species summer here. Sea coast rock pinnacles and treetops along lakeshores provide nesting sites for bald eagles, hawks, falcons, and owls.  

Katmai National Park and Preserve is located on the Alaska Peninsula. A draft list of birds present on the Alaska Peninsula compiled by the United States Geographical Survey (USGS) is available at http://www.npwrc.usgs.gov/resource/birds/chekbird/r7/akpenin.htm.
