Bay- breasteds were in a flock by themselves. Only other bird with them was the Least Flycatcher. I thought these must be Bay-breasteds when I first saw them, but some of the pics made me think they might be Blackpolls. However, the more I looked at the pics, the more I went back to all Bay-breasteds, in spite of an apparent lack of buffy or chestnut. I assume they are all young birds.
