Blue-Winged and possible Brewster's Warbler - Smutty Lane in Saco

[Brendan]

I spent about an hour down at Smutty Lane in Saco earlier this afternoon and heard and saw a Blue-Winged Warbler singing, flitting back and forth across the street.  I also got very brief flashes of a bright golden capped warbler which appeared to fly into the same tree as the Blue-Winged.   Shortly thereafter they both flew deeper towards the power line cut and I was unable to relocate either of them.  I definitely don't feel confident enough to report it on eBird as a Brewsters (it very easily could have been a Chestnut Sided) but figured I'd report it here for any members who are in the area this weekend.  Smutty Lane is one of Maine's best spots for Blue-Winged Warblers and there was great diversity there today including a lot of Prairie Warblers as well.   My sightings were right around 81/86 Smutty Lane - ebird Checklist from today below.
