CoBirders,

In my “eBird Alert” for Colorado this morning was a mention of a Graylag Goose in the lakes at City Park in Denver. The comments were: "One graylag goose was seen by the lakes. There are commonly two that winter in the park.”

What’s the “opinion” on this/these bird(s)? Apparently they aren’t resident, but are they “countable”, or simply a couple of domesticated animals that float around?

Thanks,

Two domestic Graylag(ish) geese have been resident at City Park for at least the four years that I have been birding City Park. They do not migrate and are present in the park all year round.

They aren't countable because they aren't a self-sustaining population. I suspect that they have produced a few hybrid offspring with Canada Geese. This bird from a few years ago is suspicious: http://ebird.org/ebird/view/checklist/S16035094
