When we visited the boardwalk within Potter Marsh, one of the first things we noticed was a Red-necked Grebe and its chick. They were swimming together when we first sighted them, but it didn't stay that way. Momma Grebe would occasionally swim off and then come back with a fish. I expected the chick to gobble down those fish pronto, but that was not the case. Two different times the chick had a nice yummy fish dangled under its beak and shoved into its face, but baby Grebe wasn't biting. This miniature pile of pictures tells the story. In the last picture, Momma Grebe is probably saying something like "Eat the damn fish!"
The missing picture is Momma Grebe giving up and eating the fish herself.
