Yellow-green Vireo refound at same location today (Friday)
Considering the difficulty of separating first year Y-g and Red-eyed Vireos this is slightly tentative but appears to be subject species. If chasing this bird I recommend birding starting from the fishing float and going east for 80 yards or so. To see photos go to "explore hot spots"on eBird and then selecting Lake O'Neill to see Charles Jackson's report.
