Washington State and County Checklists
Checklists follow the taxonomic order of the American Ornithologists Union, currently "The A.O.U. Check-list of North American Birds, Seventh Edition, including Supplements".
County checklist abundance codes, located after bird names, are as follows:
- 1 = Common
- 2 = Uncommon
- 3 = Usually seen every year
- 4 = Rare
- 5 = Fewer than 5 records
- X = Extirpated
- I = Introduced
If you disagree with species listed or abundance codes on checklists please contact at email@example.com. We welcome your willingness to help us present checklists that accurately reflect the birds in Washington.
If you observe species not listed on checklists, please send information about those species to at firstname.lastname@example.org.
