Last October we were down at the Western Field Ornithologist's annual meeting in San Diego. On a pelagic trip we saw a number of Oystercatchers, one of which on first glace was American. The experts there were able to point out the various (small) signs of hybridization. If I recall, the conventional wisdom was that most "Americans" seen north of Mexico were hybrid.

I have a question for those of you with experience birding Southern California. I photographed what appeared to me, to be an American Oystercatcher in Ventura Harbor on Friday. I was on a boat and did not get optimal angles on the bird, it was kinda facing away. I backtracked to the spot when I got off the boat but the bird was gone. I saw a white underside and just assumed American, not sure if I got much of the breast. Now sitting at the airport I did some googling and found some articles on hybrids in this area. I am going to upload photos in a couple days but I was wondering what the odds are of the bird being a hybrid and not a pure American Oystercatcher in that area.
