Can anyone say whether these Canada Geese are fighting or mating?

Hi everyone

We just had a walk around our local nature reserve and there was this huge commotion where these two Canada geese(?) looked like they were having a fight. The one on the right of the pic grabbed the other one by the neck and it just wouldn't let go. All of the other birds on the lake gathered around like they were egging on their favourite and this scuffle lasted for several minutes.

After a while the one that had it's neck in the other ones beak struggled and flapped about to try to escape to the edge of the lake, but his neck was still being firmly held by the other one, and at the lake edge the aggressor jumped on top of the other ones back and held his head under the water. There was so much flapping that my OH tried clapping his hands because we really thought the poor goose was going to be drowned. When they flapped off the aggressor latched onto it's back and tried to push it under the water again.

We weren't absolutely certain whether it was a fight or whether it was just about possible that the aggressor was trying to mate with the other poor half drowned goose, but it looked really aggressive.

I think that one was actually trying to kill the other one, because the one that was attacked seemed to try everything it could to escape but it just couldn't get away. It tried getting out of the water, on the landing area where people feed them, but the other ones beak was still clamped around it's neck no matter what it did. Eventually they disappeared further over the lake where the bushes were really dense and we lost sight of them.

Best wishes Chris
