Cackling goose

The weather was spring like here today. So the usual photographs were all by the pond with their sophisticated equipment. I of course tried to tap on their experience and expertise.
One of them told me that out of all these 8 geese ,7 were cackling geese. Only the very last one was a Canadian goose.
These were babies ,hardly bigger than a mallard. The white bib on the geese distinguishes them .the cackling from the Candian.
