Date: January 15, 2019 Compiler: Allison Hilf, [email protected] E-mail: RBA AT cobirds.org This is the Colorado Rare Bird Alert for Tuesday, January 15, sponsored by Denver Field Ornithologists. Rare, out of place and out of season species include: (*) indicates new information on this species; CAPITAL LETTERS are used for very rare species, as listed by the Colorado Bird Records Committee. Barnacle Goose/Pink-Footed Goose - Weld County Note, both birds are extremely rare vagrants to Eastern North America; almost unheard of in Western North America. Pink-footed Goose is very rare in captivity; whereas Barnacle Goose is somewhat common in private agriculturalists collections.
Populations of both of these geese are increasing in their breeding habitat, with about twice as many Barnacle than Pink-footed Goose. Both birds are also expanding north over the top of Greenland and could end up in NE Canada, putting them close to Goose populations that winter in the Great Plains. Steve Mlodinow posted a thorough summary on previous sightings and detailed rationale for the Colorado Bird Records Committee to ponder. Paul Hurtado also suggested the following pdf from ABA Birding Magazine about Greenland Geese: http://publications.aba.org/birding_archive_files/v40n3p46.pdf There is no guarantee either of these is a wild bird and/or that either will be accepted by the CBRC; but this might be your only chance to see them in CO. Both birds were last reported yesterday (Dec 14) at Frederick Lake (Milavec Reservoir) & Recreation Area in Frederick. The Pink-footed was reported until noon; the Barnacle was reported as late as 5pm. Observers have been diligent in reporting sightings on CObirds; please keep reporting all sightings on CObirds and check for any location updates.
