观察细节
After external consultation, this appears to be the best ID. This bird was initially seen in the Cowichan Valley back on November 9th off Thain Rd (Cobble Hill). At that time, the flock that was around had more Cackling Geese (mostly taverneri, seemingly). This bird appears on the larger end of the scale for Cackling as a parent, so it presumably pertains to a larger subspecies (e.g., taverneri). Separating it from a Lesser Canada Goose x Greater White-fronted would be challenging, but the bill on this bird does appear on the petite side for that combination.
