The open water of the tank continues to provide a safe haven for a variety of waterfowl and again both Tufties and Common Teal were the highest in number. The former reached a total of 217 while the latter totaled 312. Also present were 12 Pintail, 1 Common Pochard, 47 Shoveler, 68 Mallard, 12 Gadwall and 112 Wigeon. There were still 18 Mute Swan with a solitary juvenile Great Crested and 30 Little Grebe a new high total for the autumn build up.
Shorebirds were again low-key but 6 Avocet, 15 Ruff and a single Greenshank made some headway into the recent slump of waders.
The mitigation area of No.3 tank was again woefully poor but a juvenile Marsh Harrier was present for some time hunting the Canal Pools and the Score embankment with numerous Raven for company. A second bird was watched circling high over the estuary at the same time so, that could either be a migrant moving south or one of the other two from the summer?
