Thanks,
I spend a lot of time in the water hunting for feeding spots and clear patches when I'm at the lake. I know the course of the old stream bed, and pretty much know when the shallows get to swan reach depth.
The swans can get to be a right pain. There are 3 pairs on the lake, one at the dam and who is extremely dominant and a pair two thirds of the way up who regularly argue with the shallows pair. We then have as many as 150 to 200 transient swans who are not yet old enough to have a territory that have been ejected by their parents. The dominant pairs (males especially) will attack or bully them.
The Fens on the Norfolk and Suffolk border are a big area for the younger swans. We don't feed them, but some of the reserves do.
For us swans can get onto bait or go through lines with absolutely no idea, yet geese and ducks avoid the lines.
