Other notes
Little Grebe refound where I saw it on Monday: probably been lurking in the reeds all the while.
c.120 Black-headed and c.250 large gulls were present at 7:00am and seemed to have roosted although another c.50 large gulls dropped in by 7:15am so they could have all been very early arrivals.
The 2 Great Black-backed Gulls were different bird that arrived and left on their own.
Only two pairs of Gadwall noted this morning but conditions were far from ideal.
Cetti's Warbler in the NW area today, close to where I first noted it.
Large passage of Jackdaws this morning.
3 Ravens as a pair and a single much later.
Another species of fungus found: probably Clitocybe nebularis (aka Clouded Funnel or Clouded Agaric).

This fungus is probably Clitocybe nebularis (aka Clouded Funnel or Clouded Agaric). In Wikipedia it is noted as poisonous: elsewhere on the web it noted as “edible but causes gastric upsets in some people”.

The underside with crowded gills. I am afraid that while ‘gardening’ to remove the dead leaves and twigs to get a better shot I inadvertently uprooted this fruit. There were several others nearby.

Not often a Grey Heron allows this close approach.
An adult beginning to acquire the yellow bill of a breeding condition bird.

Here standing the Wesley Brook we can see it is not yesterday’s bird from The Flash as it has both feet undamaged.

Trench Lock Pool: 9:43am - 10:27am

 (54th visit of the year)

Possibly 2 Grey Herons today: 1 seen at S end; later 1 flew in from N. Not seen together.
Unusual preponderance of Herring Gulls among the rather few large gulls present.
Kingfisher again.

Count of birds passing over here
- 6 Redwings

The counts
4 Little Grebes
3 Great Crested Grebes
1 Cormorant
1/2 Grey Herons
2 Swans
26 Canada Geese
8 (5) Mallard
3 feral Mallard-type ducks
46 (18) Tufted Ducks
14 Moorhens

This Black-headed Gull seems to have caught a fish! I had to check with the web that this species eats fish – amongst almost everything else. Seems likely it was an opportunistic ‘find’ rather than a fishing expedition as such.
