This is the Colorado Rare Bird Alert for Tuesday, January 8, 2019, 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.


Note this is a rare vagrant to Eastern North America; and extraordinarily
rare in Western North America. However, populations of both of these geese
are increasing in their breeding habitat, and as of 2015 there are thought
to be approximately twice as many worldwide Barnacles (880K) as Pink-Footed
(410K). Note that Barnacle Geese are for sale as collector's/barnyard
specimens to a much greater degree than Pink-Footed Geese. Barnacle Geese
are sold as close to Colorado as at least Wisconsin and Michigan, and, so
far, no midwestern or western state with sightings have included this bird
on its state list. Stay tuned to CFO's website to see what the rare bird
committee ultimately decides, but this might be your only chance to try to
see one (in 880,000).
