Common Cranes at Dawn, Lac du Der, France on 10th January 2021 – by Colin Hunter

“At 48 km2, the Lac du Der is the largest artificial lake in Europe, built in 1974 to regulate the river Marne and help protect Paris from flooding. The lake has since become a paradise for birds and is a main stopping point for Common Cranes during their migration from north to south in late autumn and from south to north from mid winter. This recording features the Common Cranes as they take off into flight at sunrise, recorded in early January of 2021. Having rested overnight, the birds fly off in groups, with hundreds, sometimes thousands of individuals calling out. Their morning flight is usually to surrounding fields where they search for food, before continuing their migration.”
