Good to point out. The first day that Nick found them and I managed to get down there, I did look the Northern rough-winged over and saw no obvious pale rump and nothing else, as you mentioned to suggest the species.

With birds following the coastline and becoming attracted to that small nucleus, it's conceivable that something else could show up...

  From Greg Hanisek

  11/28 New Haven, East Shore Park - 3 CAVE SWALLOWS, 3 N. ROUGH-WINGED SWALLOWS, 1 Palm Warbler

  The unusually late appearance of N Rough-winged Swallows (in a seasonal context they're rarer than the Cave Swallows) has drawn some inquiries from outside CT about whether we've considered Southern Rough-winged Swallow, a Central and South American species. 

  This is a reasonable question when a bird appears well outside its normal seasonal context: Could it be some other mega vagrant?

  Mark Szantyr, always on top of such things, did broach the subject when the first N. Rough-winged was reported a couple weeks ago. On my two most recent visits I watched the Rough-wingeds as closely as I could and did not see key features that would suggest the birds might be Southern Rough-wingeds. They lacked the paler rump and rufous-cinnamon highlights on the throat that the literature lists as Southern Rough-wnged features. Nick Bonomo also looked the birds over closely and saw no non-Northern features. I noticed on some video I found on the Web that at least some Southern R-w have a pale nape that results in a capped appearance. The East Shore birds do not show this feature.

  Separating these species in all plumages and at all ages apparently can be quite difficult (they were once considered a single species), but our birds offer no suggestion that they're anything other than record-late Northern Rough-winged Swallows.

  Very interesting, and as noted before, this location merits as much attention as birders can give it.
