Dale, St Brides, Goultrop & a strange Diver?

A pre-breakfast trip to the airfield, turned into a bit of an epic!
Dale Airfield;-
First thing this am.,a flock of 18 Chough & several more pairs feeding around the runway. A flock of 8 Ravens, & several flocks of 20+ Meadow Pipits, with 1-2 Pied Wagtails & Reed Buntings mixed in. 2 pr's of Stonechats seen displaying. Still v. good nos. of Snipe in all the boggy areas with c20 flushed. The pond had a Mallard & a Heron. A large imm. female Peregrine was probably the bird we saw with Dave A. on The Gann y'day.

The Gann at 0900;-
2m & 6f Goldeneye, 5 Dabchick , 4 Little Egret, a single Greenshank & 7 Brents. No Med. Gulls seen ( despite of Dave's incredibly useful id session last night; more practice needed by pupils.)
60+ Curlew.

St. Brides Haven;-
A fem Merlin that obligingly perched on a wall by the castle. A juv/1w Iceland Gull feeding a bit like a phalarope very near to the cliffs to the east of the haven entrance. This could well be the same bird reported on the Blog c10 days ago, & which I thought I had seen (c2 weeks) ago with-out bins. Several small parties of Razorbills off-shore.

Goultrop;-
Several small groups of up to c10 Razorbills off Little & Broad Haven. A Marsh tit seen & heard calling right from the Coast Path. More scoter than I have seen in the area all winter: at least 60 in the same area as the Razorbills, mostly in pretty tight groups of 5-10, the largest c20. At least 1 male with a visible yellow mark on it's bill.

We also watched for nearly an hour a strange diver that progressively drifted W & then fed from Goultrop Roads to under Borough Head(SM837 129).
From a distance it was v. dark grey on top, with a white front & neck, but a largely dark head; the division of the black & white was pretty sharp & distinct. Close to, & in the 'scope, it had the shape/size of a Black throated Diver, & a finer bill than any of the Great Northerns we have seen in the area this winter, & the head did not have the obvious sharp forehead. The body appeared brownish in some light, with white speckles on top of the back. There was a small amount of white on the face behind the bill, & a slight amount of white going from under the chin to behind the neck, but definitely no white patch by the tail. Any ideas anyone?

Back for a late lunch!
