Fern Ridge Wildlife Area west of Eugene sees a variety of birds and other wildlife. It seems to be along the migratory route of some species of birds. I was fortunate to locate some American White Pelicans on a recent visit. Pelicans are large birds, capable of traveling long distances.
I found this information from 'All About Birds' helpful - "Though American White Pelicans breed at fewer than 60 colonies in total, their large size and propensity to travel large distances, even when breeding, make finding them fairly straightforward. Finding them depends on where you are and what time of the year it is, so check a range map to find out whether you should be looking in inland sites in the north or coastal spots in the south of the continent." https://www.allaboutbirds.org/guide/American_White_Pelican/id)
