Sunny Pine Warbler in a Feeding Flock, with Chipping Sparrows and Phoebe
On the same morning in early December – mostly quiet all around – a feeding flock of several dozen small birds spread out across a large grassy yard under several pecan trees, rustling around like dry brown leaves, so low to the ground and kind of in the shadows, they were all but invisible, even though there were so many. I might not even have seen them except for one bright yellow Pine Warbler among them that brought them into focus – lots of Chipping Sparrows, Yellow-rumped Warblers, several Eastern Bluebirds, a few Dark-eyed Juncos and House Finches swarmed over the grass, creeping and pecking. Two Carolina Wrens trilled and burbled around the trunk of a tree. An Eastern Phoebe even fed on the ground with all the other birds, searching the grass and leaves, foraging like the sparrows, making me wonder if maybe the cold of the early morning had made ground insects sluggish and easy pickings.
Then something startled part of the flock and Chipping Sparrows, Bluebirds and Finches flashed up, several at a time, into the low branches of nearby small trees. Dark-eyed Juncos scattered into a thicket, jingling with low, muffled alarm calls. Yellow-rumped Warblers fled in all directions, calling check as they went. The Phoebe flew to a low branch, bobbed its tail, and flew off to hover at a small hollow in the trunk of a tree, coming away with an insect, probably plucked from a spider’s web there.
