Grey Herons often eat fish, usually quite small fish. Occasionally a Grey Heron will catch something larger. This one, at the Millennium Wetlands on Thursday, June 12, caught the largest fish I have ever seen a heron catch and manage to eat. The eel was wriggling so violently the heron had to drop it and stab it repeatedly, trying to kill it. The heron then picked up the eel, flew a few metres and landed.
