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 Chris Rurik Westminster CO On Tuesday, December 13, 2016 at 11:01:32 AM UTC-7, Gary Brower wrote: > > CoBirders, > > In my “eBird Alert” for Colorado this morning was a mention of a Graylag > Goose in the lakes at City Park in Denver.
