I suspect this is a double family, two Mamas and their babies (teenagers?) They were peacefully working the lake when this jerk persisted in going too close with row boat and oars. No idea how to respect nature.
This is the jerk. I finally yelled at him, but I don't think he understood - safety first. I wish the Mama goose would have attacked him. Then he would have gotten the message.
The Mamas finally led the babies onto land where they had choice "Salad".
Back into the water. Off to greener pastures.
