A chickadee on one of the clematis trellises was hopping gently about, flapping its wings slowly from time to time as though it were trying to attract attention. Binoculars established that it had a large green caterpillar dangling from its beak--a bit too large of a mouthful to handle on the fly, as it were. Was it signaling for its mate? (or "displaying happiness"?)

After a while it did attract attention--a female cardinal (quite a bit bigger). After the cardinal hopped still closer the chickadee decided it had urgent business elsewhere--not in the direction of its nest box.
