I've never seen a flock of pine warblers, just one or two at a time, but there was a flock outside earlier when I was working on the house. I had to stay still on the step stool because they were flying by me (one tried to land one me
).
So cool! They were in the pine straw, the crepe myrtle, the pine trees, and they were eating the suet. The male bluebird even showed up to see what the fuss was about.
