Brent logistics

The two wintering Pale-bellied Brent Geese (note also a third bird south towards Potts Corner on at least two dates) have been difficult to locate.  Malcolm has worked out a pattern:

It is clear that the lowest high tide resulting in a sighting on south side was 8.4m.
The northern side is less well reported, but 3 of the 5 records were for tides less than 8.0m. The "anomaly" being the record on skeer just to north of HH on 31/12 on 9.05m tide. However I suspect this would have been quite a while before high water, as this skeer is covered early.

In summary: it appears that the north side is favoured, until tides are sufficiently high to force the birds to the south, for the duration of high water at least.

Todays sightings
Brent Goose - two PB on OE saltmarsh at HT
Stonechat - female still around OE saltmarsh
No sign of yesterday's singleton Twite on OE
