Given the extremely remote outside chance one of those fall kingbirds could be a Couch's Kingbird (haven't they been recorded in CA.?) does anybody in Oregon pay any attention to their vocalizations? I've seen quite a few fall Kingbirds, but only one of them ever vocalized, and it gave the typical twitter of a Tropical. All the others have been silent. What experiences have others had in this regard?
