Like trumpets – that's how Leon describes the haunting calls of common cranes. To photograph them, he and his dad got up while it was still dark and crept into a hide on the shore of Lake Galenbecker in northern Germany. The lake is a staging post for migrating waterfowl, including thousands of common cranes. On this morning, a wall of mist rose up over the lake at sunrise, and for a while, Leon could barely see anything. Then, for a short moment, the mist dissipated, just as a group of cranes flew by. Leon focused on the submerged trees to help keep the birds sharp as the early morning sun bathed the lake in gold.
