This interesting dark-morph bird was the hot-topic of the day. Jon Dunn was immediately taken by the resemblance of this bird to a Catharacta Skua, of which there is only 1 record of for the interior( a South Polar in North Dakota).

In this bad shot, the very broad-winged and short-tailed look is obvious, and the white primary bar is visible on the underwing, this bird also had a very noticeable bar on the upperwing. Once again, hopefully better photos will be coming.
