觀察細節

Originally reported as Long Tailed Duck, as I was aware of two reports yesterday (12/5). Then identified as Ross Goose with photo-id assist from Merlin which suggested Ross and Snow Goose. Bill shape led to id as Ross, despite problematic color. Finally, (12/7) Gerry Hawkins helped me identify this as the Ross x Cackling hybrid. (The automatic species check suggested Cackling Goose for images 3, 4, and 9, and Hooded Merganser for image 5 when I identified the bird as ROGO). A similar bird (GH suggests possibly even the same one) is reported on this checklist: https://ebird.org/checklist/S210775456
