These images of starlings flying in unison across a moody Danish sky are breathtaking. The series, shot by Danish photographer, Søren Solkær captures the wonder of migrating birds. “Shapes and black lines of condensation form within the swarm, resembling waves of interference or mathematical abstractions written across the horizon,” he writes. “At times the flock seems to possess the cohesive power of super fluids, changing shape in an endless flux. From geometric to organic, from solid to fluid, from matter to ethereal, from reality to dream –– an exchange in which real time ceases to exist and mythical time pervades.” Many of his images look like abstract graphite drawings, and this one is so saturated with starlings that it could be a Jackson Pollock. They really are mesmerizing.
