Snow/Ross's Goose

A single tight flock of 32+ flew over very high heading NE into the wind to the north of the main lagoon and over the Marin Headlands at c. 8:10am-8:15am having come in off the ocean and having difficulty battling the wind. Too far away and high to differentiate the actual species involved. ID straight forward - white geese with black primaries. 5-10% were more grayish in color - presumably 1st winters.
