Atlas winter records needed from tetrads

A late-ish swallow put in an appearance at Stackpole on Thurs 25th Nov (at the Court site) - recorded by a visiting tree surgeon.

As this is the last winter season for the National Atlas it would be good if records from all tetrads in the County could be obtained. So far we have no records from the following list. Some are offshore islands/islets and some have very little land on the coast but they all count! Has anyone got any ideas about how the offshore ones could be surveyed by boat if feasible?

Tetrads with zero winter records:
SM62 L, R, S, T, U, V
SM70 E, W, X
SM71 A, F
SM73 Q, W
SM80 G, H, K, M
SM83 G, T, U
SM93 W, Z
SM94 V
SN10 B, K
SN11 U
SN13 B, G
SN14 Y, Z
SN23 Z
SS19 H, M

The following list of tetrads have only 1-10 species recorded, can you add more?:
SM70 M
SM72 A, R
SM80 T, Y
SM81 N, V, W
SM82 H, N
SM83 M
SM90 E
SM91 C, E, L, X, Z
SM93 G, H, I, S, U, V
SN00 U
SN01 N
SN02 D, L
SN03 B, C, F, K, L
SN10 G, H
SN11 D, E, G
SN13 W, X
SN14 E
SN23 Q, R, U, V
SR99 W
SS19 D

Finally, good to see at last, that the crane has appeared on the Atlas November list, and thanks Janet/Richard for adding the surf scoter too. There is only one November lapland bunting record in Pembs so far entered to the Atlas and so far no 2010 records of cattle egret have appeared. It would be a pity if none of these records ever reach the Atlas.
