Brent Goose?

New email from Roger Lane...
"All I wanted to say, if you've not been down is that there is a solitary BRENT Goose in the Bay (Harbour Rocks), and at least a couple of Sand Martins with a couple of doz. Swallows over the Pond.
Could not see if Brent Goose was dark-bellied or pale-bellied form (against light), could be either at this date ".

Unfortunately we gave it a miss this evening with friends calling in. If anyone can confirm which of the two is in the Harbour I would be glad to hear from you.

Thanks Roger for the information.
