Today's blog is done in a bit of a rush, because I have been summoned to the BBC to do an interview on Radio Five Live about the pigeon-eating Lesser Black-Backed Gull. If everything goes to plan it will be airing some time after 6 pm.

The gull himself was taking it easy on the roof of the Dell restaurant, in the same place as in yesterday's picture.

And this is the reason he likes this spot: a heaving mass of Feral Pigeons on the tarmac just below. As you can see, it is quite easy for him to run in and grab any that have not been able to take off in time.

The pair of Mandarins at Peter Pan have become very familiar, and now come out of the water when they see me, expecting to be fed.

If any pigeons should try to interfere, they get the bum's rush.

The east side of the Long Water is now wall-to-wall Pochard. The is just one Tufted Duck and one Red-Crested Pochard in this crowd.

The Shovellers are most up at the north end of the Long Water, but this solitary drake had come out on to the Serpentine and was resting near the edge. Shovellers are generally rather shy, but this one was taking no notice of the passing people.

Two Nuthatches appeared at the southwest corner of the leaf yard, a place where two pairs bred this year. This is one of the pair that nested in the old chestnut tree just inside the railings.

I didn't have time to wait for the Tawny Owl to come out today. But the male Little Owl was in his nest tree, in a slightly more secluded spot than usual.
