Fly over of approx. 20 trumpeter swans
I think these are Cackling Goose (Geese) - and I have included a video link if you (and others) wish to hear the calling and see the markers - which are higher pitched (whistling) and seemed much smaller (IMO) than Canada Goose; they all settled into a field near the tidal flats

anyway we shall see: I lean toward Cackling - rather than Canada with this group.
