We often see cormorants in the UK, usually the odd specimen perched fishing from a log or rock, sometimes in small groups. It was quite refreshing, then, to come across a large group of hundreds of these birds, perched in trees around a lake at the Dranse estuary nature reserve near Thonon-les-Bains on the southern shores of Lac Leman (Lake Geneva).
There was a constant to-ing and fro-ing, with a smaller number of them directly fishing from the lake surface or in characteristic wing-drying pose.
The size of this population is a testament to the health of the waters and fish populations in Lac Leman.
Of course, you will also see cormorants by the sea, as they can live with both salt water and fresh water.
