One was up in the grass.
The other 2 were down in the muddy water. Can you see the baby? It's camouflaged.
It looked as though this was a family of 3. The parents were telling their baby, "Get out of the mud! You're going to get stuck, and won't be able to fly away!"
Soon after I took these photos Isaak fell in the muddy water further downstream. Where the water was deeper. It's probably because I wasn't getting after him. I was too busy watching the birds discipline their young.
Random: Isaak swears that he speaks bird. He tweets a tweeting noise. Birds actually tweet back.
Do you think other animals besides us discipline their young?
