40 Common Scoter & 6 Wigeon north, 5 Shelduck & 2 Brent south is not exactly riveting stuff and then the fog rolled in from inland at 0850hrs so that was that. Also noted 2 Greylags that came in from inland before going north then changing their minds to go south.These will be a local pair searching for potential new nesting sites to colonise (or pollute depending on your opinions of feral Greylags). A single Mute Swan low of the observatory roof then inland up river is also quite likely looking for an unmanned water body to take up residence on. A mild spell then some birds minds turn to spring but with a colder spell due this weekend might just cool there ardour.
