Last week's quiz was a little tough, I admit. The problem with white geese is they are all so similar and with this one you had to look very closely at the image to detect the lack of a "grin patch" to identify it as a Ross's Goose. The other major differences are a more rounded head and smaller, both tough to see from that angle. This week we have a species I have only heard since arriving here but last week a couple on the bird walk mentioned seeing them the previous day just outside Bryce.
