Marsh Harrier at Marloes Mere

I bumped into Derek G at the Marloes car park this evening, and we walked towards the Britton hide in the increasingly cold wind. Almost the first bird we saw was a Marsh Harrier, probably a juvenile, with several inner primaries missing. Is this the same bird seen on Skomer earlier today?
Other highlights were at least three singing Reed Warblers, and a couple of Sedge Warblers competing against each other from gorse bushes no more than five yards apart.
There remain good numbers of Teal around: I counted at least 15, with the males' plumage in fantastic condition. Several of them were displaying, suggesting that some, at least, are likely to breed at the Mere this year.

Elsewhere: Dale Airfield felt very empty this afternoon: a lone Curlew, two Greenland Wheatears and a pair of Chough feeding on a runway. A pair of Canada Geese have a single gosling on the pond. There was also a flock of 40+ Linnets.

Western Cleddau at Nant-y-Coy last night: a Dipper and a two Peregrines. Again, no Kingfishers.
