The Quiz: Which of these is not a regular part of the red-necked grebe’s diet?

A Seaweed
B Fish
C Its own feathers

The red-necked grebe mainly feasts on fish caught by diving. But like other grebes, it also has the habit of eating its own feathers, sometimes even feeding them to its young. Ornithologists aren’t entirely clear why the grebe does this, but it’s thought to aid digestion or to reduce vulnerability to parasites. Quite the plucky dietary choice!

The correct answer to this quiz is Seaweed.
