Mr swam and his friend Mr leech

Went out today with camera in hand only for the battery to die within two shots!! :-(
Schoolgirl error!!

Anyway, I'd been watching this leech make it's way up the swans neck! Onto its face.
Yuck!!
My feet were freezing by the time we got back. . . 2 and 1/2 year olds don't walk very fast!!
