GREY HERON Attacked by COOTS

The heron is in the water with a broken wing and cannot get out after being viciously attacked by coots.
This young heron was on a public footpath when it was disturbed by a pedestrian and it flew to the island. Unfortunately, it landed close to the water where the coots have a nest. They instantly attacked the heron and, as it tried to flee, it ended up in the water. Its wing was broken and it was unable to get out of the deep water. It was helpless. The coots continued to attack the heron, whilst in the water, and a couple of geese joined in as well. Even the little moorhen tried to smack the heron. It seemed like every bird in the lake wanted to batter the poor heron whilst it was defenceless.
When the heron was exhausted, the coots and geese sensed that it was no longer a threat and left it alone to suffer.
When I returned to the park, about an hour later, the bird had passed away.
