Climb to feeding ground - Seq#1

The family of 4 ducklings came in from the stand still water of a bypass in the river(botom of photo). The mother wants the kids to climb to the main stream of the river (top of the photo). Through all the processing I heard no sound from the mother. Everyting is done under 1 rule : stay close to the mother. The mother split the climb into 3 steps. I started shooting when she was standing on the second step. She will let them find their own way to join her. Keep in mind that she is big and heavy enough to climb straight up. but the kids needs to avoid heavy droping currents.
