John Graff mentioned that they are unlikely to get Wedgies off Albany, although
the photos show how closely abnormal white markings on brown birds can mimic
the appearance of other species.
The petrel you reference below is another classic example. It shows how easy an
abnormal bird can pull opinions in the wrong direction first up. However, such
abnormalities are relatively rare, and therefore I think it's only logical to
think of the most likely fit when given a set of plumage descriptions.
