Should I call this bird "wild goose" or "Anser albifrons" ?
On the premises of Hokkaido University, you can find this bird near the pond. Green-headed gander also can be seen usually but I could not find it on the day.
Have you seen a black woodpecker ?
You can hear the woodpecker knocking on the tree to get worms on the premises of the university.
Have a nice weekend !
