Vireo

[BetCrooks]

Seen hunting mid-tree height. Lots of small flying insects in the leaves.

Is this a Philadelphia Vireo? Or something quite different?

Either way, it was nice to watch it finding lots to eat.

Yes, I think it is a Phila vireo due to the bright yellow chest.  Warbling vireo can have some yellow on the sides in the fall but should not look that yellow in the chest.  See here:
