Testosterone

I had a day off so did some book-shifting and guitar-playing. Went round the block to take a photo of faded bay markings for the car club and chanced upon a big swan fight on the water. Lots of chasing up and down, busking and flapping. In the end Mr Leith swan (whose rear end you're looking at here) had to take to the air to repel the intruder who flew off at great speed up the WoL. After a few minutes our chap flew back in triumph to re-join the missus.
