A Lesser Black-backed Gull seen in North Plymouth this fall has fostered speculation as to whether it was the same individusal as has been seen for several years at Jenny's Mill Pond on the southern part of town (certainly not a very long flight). Speculation has been that they are f2 different birds since apparently the Jenny's bird hasn't appeared to wander much over the years.

I managed to get a pretty close head shot of today's bird that can be compared with one I took in January of the the Jenny's bird (click next in upper right to see it). Based on differences in the density of the dark markings near the eye and especially the markings on the bill, I think they are definitely two different birds.
