Before I left home, there were a couple Pine Warblers moving through the trees in front of my office. That was a good sign. Hopkinton State Park, on the other hand, was virtually deserted. I only saw a couple of American Goldfinch and an American Crow. Not a single warbler.
One lonely Clouded Sulphur flew fast and low over the closely cropped grass bordering the parking lots. It stopped briefly at every tiny excuse of a flower. It was pretty slim pickings, and I wondered what happens when the nectar is few and far between. Do they run out of energy to make it whatever distance is required to the next flower?
