Hi John,
I have 14 butternut & heartnut trees that are severely skeletonized each
year in July. I had mixed warbler feeding groups in these trees each day
roughly July 29-Aug 4. I have eBird reports in for those two dates that
include all of your top 7 species, plus Black-throated Green and Nashville.
I felt the majority of these birds, more than half juveniles, were
migrants, altho several also nest locally. I felt they were migrants
because they were all there together, especially each morning.
