Hungry Humbugs

We spotted a pair of great crested grebes from the wobbly bridge. I then noticed that each had two zebra-headed grebelets on its back. Soon afterwards, one of the adults, the male I think, reared up out of the water and turfed its two offspring off. They soon scrambled onto the back of the female with their siblings. Father grebe went fishing. My image shows the four humbugs reaching for a tiny fish that he has caught.
