A good find for this area.
Seemed like wild birds, they were very distant and acted wary. A few minutes into observing them, the flock took flight, and flew off to the south.
Mixed in with these geese was one markedly different individual, cropped in on the second photo. Seems to match Sibley's illustration of Canada x Swan Goose. Have posted that bird as a separate observation now:

The Canada Goose (Branta canadensis) is a goose with a black head and neck, white patches on the face, and a brownish-gray body. Native to arctic and temperate regions of North America, it also occasionally migrates to northern Europe, and has been introduced to Britain, New Zealand, and other temperate regions.
