I watched a couple of Little egrets going for it this afternoon at Walmsley Sanctuary.
Initially I wondered if it was some kind of courtship chase but then things turned quite aggressive (could still have been courtship!).
There was one particular bird that wanted to attack all the other egrets in the reserve and it kept picking on others until this time it looked as if it was going to drown the other unfortunate bird.
Here is a short sequence of pictures taken from a fair distance away hence the poor quality!
Both birds flew away seemingly unharmed!
