Indigo Bunting at Governor Bridge Natural Area.

I was very surprised to find temps in the high 60s when I was leaving, and I quickly donned warmer clothes,
Governor Bridge was really very quiet. Yellow Breasted Chats were nearly ubiquitous two weeks ago, and I didn’t hear any at all today.
Birding was very slow in general, but butterflies were unusually active. Are they fueling up to migrate?
