This might be a Ross's Goose, -- white goose feeding near the swans, - am not sure which type of goose this is, but it's not a Snow Goose. Like the red/orange beak and red legs. It dredged up a beakful of grassy stuff from the bottom of the river here, which it seemed to be eating :) Think I got a couple of images with the goose with it's beak full.
