Description:

These geese have been visiting Yarrow Valley Country Park for some years now but last year they breed for the first time. There were only 2 goslings and, unfortunately, the resident male mute swan killed both of them within the first few weeks.

I remember a pond in Kidderminster -

where nature was truly red in tooth and - claw - or at least beak and webbed feet!
The swans tried to kill Canada goslings, both of these species persecuted mallard ducklings; and just about everyone concerned (including their own parents) attacked coot chicks.
To add to the fun, there was a very large pike that also took the young of anything that swam.

Survival of the fittest

Nature is as it is, I suppose.

I have heard others say that they have seen coots attack their own chicks but I only ever seen them taking care of them.

I once saw the swan jump right out of the water, in pain, shaking its foot and I did wonder whether a pike had bit it.

Coot chick persecution -

I'm not sure how common it is, I only saw it once, and read about it as a result. It may be a response to food shortage - selecting the weakest chick that would probably not survive anyway, to give the others a chance. "Selfish genes" in action?
