Kathryn Cooper. Aerial Battle.

I photograph murmurations. Groups of thousands, sometimes hundreds of thousands of birds moving in unison, continuously reconfiguring their shape to create a mesmerising dance in the sky.

In the UK, at dusk, starlings murmurate over their chosen roost site, until, when the light has dropped, the flock descends en masse into the reeds or trees. Their aerial displays appear almost choreographed with patterns emerging and dissolving in the sky.

I cannot help feeling awe and wonder when witnessing hundreds of thousands of individuals moving with such cohesion. The birds neither collide nor disperse, effortlessly avoiding obstacles and evading predators.
