Checklist of Birds

The Klamath Basin is internationally renowned for its great abundance and diversity of birdlife. Of special interest are the large concentrations of waterfowl during spring and fall migratory periods. Peak numbers generally occur in early November and late March or April. Klamath Basin wetlands are among the most prolific waterfowl and marsh bird production areas in the Pacific Northwest. During the spring and summer, large numbers of waterfowl and other water bird young can be viewed. The Klamath Basin is also host to the largest concentration of wintering bald eagles in the contiguous United States. Some years more than 1,000 of these majestic birds are present with most daytime use occurring at Tule Lake and Lower Klamath Refuges.

The lists contain 274 regularly occurring bird species. Another 77 casual and accidental species are shown on a separate list. The checklists were prepared in accordance with the latest edition of the American Ornithologists' Union Check-list of North American Birds (44th Supplement) in cooperation with several Klamath Basin birding authorities.

The sighting likelihood of a bird may vary within a season. The chance of observing each bird on this list represents the highest chance of seeing the species within that season.

The up-to-date Birding Checklist is presented as a PDF file.
