Ross's x Cackling Goose - Weld County CO - December 2019
This bird is atypical for a Snow/Ross's x Canada/Cackling in that there is rater limited white on head. It is closer to the size of CACG than most of these hybrids, but is still looked smaller in the field over a period of prolonged observation. Also, there is no grin patch, and the bill is no longer than that of a Cackling. Notably, bill length and depth of Ross's Goose overlaps extensible with Richardson's Cackling, with Snow averaging distinctly larger in both.
