Back blip from trip to London. 
Had a wander round Ravenscourt park with mum before meeting my aunt and cousin. Spotted this coot on its nest. Also saw a baby coot with parents on the grass nearby. Walked down to the riverside at Chiswick and then it was time to take mum off to Paddington to catch her train home. I went on to Liverpool Street station to catch my train to Cambridge - spending the bank holiday weekend there with Dennis.
