On a day I spent watching birds sing, from yellow-headed and red-winged blackbirds to song sparrows and marsh wrens, this little barn swallow was the only one not singing. After swarming over the lake hunting insects with the rest of the barn and tree swallows, he landed on this cattail for just a moment, opened his mouth wide a couple of times, preened a few feathers, then took to the skies once more.
