What's this swan doing?

[IHeartHalloumi]

Large pond with multiple swans - 1 in swimming round with it's wings rucked up - doesn't look injured. Is this a dominance thing? Several adults and juveniles here.

Threat display, usually towards anyone on their territory, especially if they’re around the nest or cygnets. Sometimes accompanied by hissing.

Is that likely to be directed at humans or other swans? There is a nest but at other end of pond (about 100m away, has swan sat on it). I'm a bit surprised by the number of swans here - I think 4 juveniles still with some brown feathers and 7 all white ones (some smaller than others). People about but no one too close. There was a swan off a couple of years ago with 1 presumed killed by another

I'd keep well away from that swan!

Could be either.

It's territorial display language warning people and dogs to keep away. Give it a wide berth!

Birds are very territorial at this time of year. I was walking down a canal path, minding my own business, and passed a Canada goose sitting on the bank. Next thing, the goose was up and chasing me, trying to jab at my legs! I felt very silly running away from a Canada goose but believe me, I would not have come off well had I stood my ground.

They can be quite aggressive if they feel a threat in any way

I think it's probably being aggie to other adult swans - similar behaviour today and a bit of hissing at other swans. Hopefully means it'll be a good parent

It means that it wants to break your arm
