Difficult to be sure in this image, but if those (Blackburnian like) earcoverts are as solidly dark as they appear to be in the image one would hesitate to call it BTGW, but the unmarked upperparts and a dark malar like stripe looks better for BTGW.

I don't know guys. As Jan said, that auricular patch is so uniformly dark looking and triangular looking it's hard not to say blackburnian. I know there should be more markings on the back, and there is a hint (although I'm not convinced) of a malar stripe. I lightened things up a bit. Have another look and tell me if you still think it's BTGW.

Well Scott,
I think we landed quite right with BTGW anyway. As I made a point on the birds solidly dark earcoverts I forgot to mention that the yellow patch under the eye usually has some contrast against the earcoverts (usually stronger contrast in Blackburnian) is not seen in Steveos bird. I think I even can see some yellow in the vent. Some variation in the intensity of the dark on the earcoverts in BTGW is noted:

Ok, I'm convinced. Those first couple of photos definately show the same pattern. BTGW and BW are two birds that I instantly recognize in the field, spring or fall, but I guess the posture and low resolution through me a bit.

Thanks,
Scott
