Greater White-fronted geese have occurred at Green Lake on and off over the years.
Often a lone goose hanging out with various domesticated geese and/or ducks.
Since I haven't done my (at one point) weekly census since I moved away from the lake five years ago, I can't vouch for recent occurrences. But I know there are other birders who walk the (perimeter of the) lake on a regular basis.......

Interestingly, last Wednesday night while putting the garbage at the curb (around 10:30 PM), and again this morning (at 6 AM) I heard Greater White-fronted vocalizations from on high in the sky over our house (Crown Hill area of Seattle, north of Ballard). Not sure of their direction in the evening, but this morning they were definitely heading south.

Subject: [Tweeters] Greater White-Fronted Goose at Green Lake

Yesterday when I was working at the SAS Nature Shop, a woman named Grace Thompson came in with an open Sibley's and photos of what Paul Webster and I confirmed was an immature Greater WF Goose. She stated it has appeared at various spots around the lake both on and off the water, and often loosely associates with Mallards. It has been there for several days, she reports. Having kept water fowl records re. Green Lake for several years, this is the first one she has seen there.
