Great egret awakening - Zsolt Kudich - Finalist, Birds
When the River Danube flooded into Hungary’s Gemenc Forest, more than a thousand great egrets flocked to the lake to feed on the stranded amphibians, fish and invertebrates. Working on a project to document the last untouched regions of the Danube, including the floodplains, Zsolt was delighted to find a sixth of Hungary’s great egret population in the one place. By 1921, hunting had reduced their number to just 31 pairs. Today, habitat loss is the big threat. Using the soft dawn light, Zsolt wanted to convey the impression of a multitude of birds. So he pitched his camouflaged tent nearby, sleeping just a few hours a night for five nights. His chance came when a fishing white-tailed eagle sent some of the egrets into the air. With a slow shutter speed to blur the wings and a large depth of field to keep in focus those standing, Zsolt got his memorable image.
