Do geese eat oranges

I saw a wild goose nesting a few eggs. I pushed an orange slice close to it, and, when it was close enough for it to reach it, the goose flew off with the orange in its mouth.

Before flying away, it nipped at it a bit and seemed to taste it. I assume it was satisfied with the taste.

However, I don't understand why the goose left its eggs to take the orange slice with it. I waited about half an hour and it never came back.
