Lake Clark's skies are filled with birds. Each spring the forests echo with uncountable songs. Their wing-beats flash in hypnotizing patterns along the seashore as they gather in large flocks during fall and spring migration. The tundra resounds with the calls of species nesting among the swarms of delicious mosquitoes. The winter's quiet is broken by the squawk of a year-round resident. In total 187 species of raptors, waterfowl, seabirds, shorebirds, and songbirds have been documented in the park and preserve.
Waterfowl, Shorebirds and Seabirds
Waterfowl nest and molt in wetlands throughout the area. Large migratory flocks of ducks, swans, and geese rest and feed in the park and preserve before flying from Nikabuna Lakes to Lake Clark through low mountain passes in the Chulitna River drainage. Sea ducks, primarily white-winged and surf scoters, are the most abundant waterfowl on the coast, numbering over 18,000 in mid-August.
The coast also provides important breeding habitat for mallards, American wigeon, Barrow's golden-eye, and red-throated loons. Migrating dabbling ducks number 3,000-4,000 in spring and fall. Diving ducks, primarily greater and lesser scaup, stage along the coast in spring. They reach peak abundance (16,400 birds) in mid-May. Other ducks include green-winged teal, northern pintail, harlequin, common golden-eye, black scoter, common eider, bufflehead, and long-tailed duck.
About 30 pairs of trumpeter swans nest in the park and preserve; most breed in wetlands on the coast. Canada geese occur in Tuxedni Bay and can number about 4,400 during fall migration.
Seabird breeding colonies occur along Cook Inlet and concentrate at Tuxedni and Chinitna Bays. Of the seven seabird colonies surveyed from 1994 to 1996, the largest contained 2,700 black-legged kittiwakes. Less numerous seabirds include horned and tufted puffins, double-crested cormorants, pelagic cormorants, glaucous-winged gulls, common murres, and pigeon guillemots.
During spring migration, 86,000 to 122,000 shorebirds, primarily western sandpipers and dunlin, use intertidal mud flats in Tuxedni and Chinitna Bays.
Raptors
Raptors are carnivorous birds. Raptors include birds ranging from bald and golden eagles, northern goshawks, owls, and merlins, but the three common characteristics all raptors share are a hooked beak, eight sharp talons, and keen eyesight.
Lake Clark National Park and Preserve is special for migrating and nesting raptors. About 50 pairs of bald eagles and 5-10 pairs of golden eagles are known to nest in the park and preserve. Bald eagles are considered a "vital sign" for the park's ecological health because they are an indicator of many environmental conditions that affect other species. Potential threats to eagle breeding populations include oil spills and exposure to environmental contaminants, increasing human visitation, incidental trapping, and potential climate change effects. The National Park Service's Southwest Alaska Network actively studies bald eagles in the area and finds populations to be generally stable.
Other nesting birds include two pairs of osprey in the preserve and the once-endangered peregrine falcons nesting in eyries on cliffs along interior lakes and rivers, and at Tuxedni Bay.
Songbirds
Although not all songbirds are talented singers, the array of songbirds, or perching birds from the order Passeriformes, is truly incredible! From the harsh and numerous vocalizations of the raven to a thrush’s lilting whistles, the songbird group is broad and diverse. Regarding bird species, half the world’s birds are in the songbird group! Take a look at Passeriformes in the NPSpecies tool at the bottom of this page to see the range of Lake Clark National Park and Preserve's songbirds.
Songbirds, and birds in general, have a rich and important local connection to the Dena'ina people. In "Bird Traditions of the Lime Village Area Dena'ina," authors Priscilla N. Russell and George C. West write that the "Dena'ina believe that birds use a wide variety of vocal and non-vocal actions to communicate among themselves, with other wildlife, and with humans." This perspective is an essential part of Dena'ina culture and world view as evidenced in the story below:
In the spring, people were fishing, but there were no fish. One man was sitting on the bank and listening. A bird sang, "tsik' ezlagh."
He ran into the house. "Hurry!" he said, "that bird sang 'tsik' ezlagh.'" And everyone went down to the beach with dipnets.
The one who had spread the news was watching, and a gull flying close to the surface of the water was calling "beq'ina" ['its fish eggs']. He went there with a dipnet. He jumped in the water, and he caught a king salmon.
And they marked that day. At times the fish ran earlier. At times they ran later. And they listened for that bird. Sometimes he sings later, sometimes earlier.
That is what they said. When the first salmon run, the golden-crowned sparrow sings.
-Peter Kalifornsky, excerpt from "A Dena'ina Legacy" (translated from Dena'ina)

Species Attribute Definitions
Definitions
Occurrence
Occurrence values are defined below. One or more Occurrence Tags may be associated with each Occurrence value.
Present: Species occurs in park; current, reliable evidence available.
Probably Present: High confidence species occurs in park but current, verified evidence needed.
Unconfirmed: Species is attributed to park but evidence is weak or absent.
Not In Park: Species is not known to occur in park.
Occurrence Tags
Adjacent: Species is known to occur in areas near to or contiguous with park boundaries.
False Report: Species was reported to occur within the park, but current evidence indicates the report was based on misidentification, a taxonomic concept no longer accepted, or other similar problem of error or interpretation.
Historical: Species' historical occurrence in park is documented. Assigned based on judgment as opposed to determination based on age of the most recent evidence.
Abundance
Abundant:
Animals: May be seen daily, in suitable habitat and season, and counted in relatively large numbers.
Plants: Large number of individuals; wide ecological amplitude or occurring in habitats covering a large portion of the park.
Common:
Animals: May be seen daily, in suitable habitat and season, but not in large numbers.
Plants: Large numbers of individuals predictably occurring in commonly encountered habitats but not those covering a large portion of the park.
Uncommon:
Animals: Likely to be seen monthly in appropriate habitat and season. May be locally common.
Plants: Few to moderate numbers of individuals; occurring either sporadically in commonly encountered habitats or in uncommon habitats.
Rare:
Animals: Present, but usually seen only a few times each year.
Plants: Few individuals, usually restricted to small areas of rare habitat.
Occasional:
Animals: Occurs in the park at least once every few years, varying in numbers, but not necessarily every year.
Plants: Abundance variable from year to year (e.g., desert plants).
Unknown: Abundance unknown
Nativeness
Native: Species naturally occurs in park or region.
Non-native: Species occurs on park lands as a result of deliberate or accidental human activities.
Unknown: Nativeness status is unknown or ambiguous.
List Differences
The Checklist contains only those species that are designated as "present" or "probably present" in the park.
The Full List includes all the checklist species in addition to species that are unconfirmed, historically detected, or incorrectly reported as being found in the park. The full list also contains species that are "in review" because their status in the park hasn't been fully determined. Additional details about the status of each species is included in the full list.
The checklist will almost always contain fewer species than the full list.
