Actually, two Yellow Warblers!
Both were hungrily diving through shrub branches hunting for insects. The shrub cover made them challenging to photograph and I wasn’t sure until uploading the photos whether I captured the one eating what looks like a bee.
The two photographed over the weekend were both females. They lack the brown breast streaks of the male as seen in the photo taken several springs ago (see below).
