context_page_description: This list of Oregon birds lists wild bird species found in the U.S. state of Oregon and accepted by the Oregon Bird Records Committee. As of May 2020, there are 542 species on the list. Of them, 158 are on the review list. Nine species were introduced to Oregon or elsewhere in North America; one of them and two others have been extirpated from the state.
  Bird counts often change depending on factors such as the number and training of the observers, as well as opinions about what constitutes an officially recognized subspecies. Though northern climes typically do not support as many species as southerly locations, Oregon is fifth in bird species diversity in the United States, behind Florida, New Mexico, Texas and California. This amount of diversity is attributable to Oregon's numerous distinctive ecoregions and relatively mild winter weather, which make it an important wintering ground for migratory bird species, especially waterfowl, on the Pacific Flyway.
  Another result of the state's varying ecology is the 120 Important Bird Areas, such as the Jackson Bottom Wetlands Preserve, that are recognized as important conservation sites for birds.
