Re: [cobirds] BARNACLE GOOSE in northeastern CO

Here is a link to the 60th report of the CBRC that explains in detail, the stable isotope procedure we used to help determine the status of an Emperor Goose shot in Colorado in 2008:

A hunter shot a BARNACLE GOOSE this past weekend somewhere in the northeastern part of the state (location not disclosed). It was with a second Barnacle Goose that flew off. I'm not experienced with aging then but based on the photos I think it might be an immature bird. 

While this species is always problematic in terms of provenance, there's a decent chance wild birds do make it into the great plains.

If anyone knows who might be able to run an isotope and/or DNA analysis, the hunter might be willing to part with a few feathers and/or tissue, so please get in touch with me off list! Thanks!

Good birding,
