There was also an odd white and black goose with pink legs - hybrid perhaps ??? it was hanging around the same area with the Brant. RFI for that 'odd' one; pics will be posted to a forthcoming ebird checklist.
Most of the flock, including Brant, flew out - but not too far, probably just to the fields due north of the lake. The large flock returned at ~4:30, but we were unable to relocate the Brant. Should be good chances in the morning, both in the fields or the lake.
Good Birding,
