This is really crazy and hilarious.
A pair of mallards were swimming towards the middle of the pond, then another group came over to defend its territory quickly.
The first pair tried to turn back, but the lead male duck from the second group jumped at the second bird (a female), but not the leading male duck, in the second group.
Did the leading male mallard in the second group chose the female in the invading group on purpose?
