All of the 6 Cackling Geese I found that day were of the common subspecies of Cackling Goose we expect here in the NYC/LI area, which would be the B. h. hutchinsii – Richardson’s.
|Both are Cackling Geese; note the color variation on the back as well as the head.|
If the Bill and Head pass the first two indicators above, pay attention to the size and general appearance. Ask yourself these questions. (A) Does the Cackling candidate have a shorter neck than the nearby white-cheeked geese? (B) Does the legs look shorter than the nearby white-cheeked geese?
