This afternoon in the back yard I looked up to see the sky filled with a huge (for here – 50+) flock of gulls! Prepping to migrate? No scavenging apparent – they’re all wheeling around, staying airborne. The flock slowly drifts off SE…

Meanwhile on the ground, and equally rare, is a flock of winged ants(?), milling about on the walk, surrounded by a host of wingless ant attendants… or predators – they are hauling off the occasional winged corpse. This happened once or twice earlier this summer, too – we watched, fascinated, as a host of winged creatures were escorted out of the ant-home entrance (in that case, a crack in a stump) by agitated ants. Eventually flying off, looking like tree fluff on the rise – a halo of fast-beating wings surrounding each in the sunlight.
