Swan in the pond

Caught this as I was walking into the office today. (Obviously, today, it's blipfoto.)

It's one of the swans in the pond...seemingly melting from the heat and humidity. She's not. She perked up and swam across to the shade.

(How do I know it's 'she'? The male tends to be a bit territorial. So, he's usually kept behind a fence with access to the pond and in the evening when there's fewer people about he's free to roam.
