With that said, here's a bird I first thought may be a 1st cycle Lesser, then decided it was okay for a 1st cycle Herring, and then started scratching my head the longer I looked at it.
|Structurally, the rear looks very little like an American Herring and much more like a Lesser. The sparsely marked vent area is also unusual.|
|The, longer, solid outer median and lesser coverts also resemble Lesser Black-backed, more than American Herring.|
|"This is NOT a pure American Herring" were my thoughts after seeing the undertail.|
|The white vent is not something I've encountered with juvenile American Herrings. But now see the open wing...|
|The uppertail contrasts greatly with the rest of the body, but most disturbing is the strong contrast to the pale inner primaries (only seen well in brighter lighting).|
|In this slightly underexposed image, it looks long-winged, shows less of an inner primary window, and the tail almost looks like it was trying to go for a banded look but failed miserably.|
