This is something I did not know. Now, I have to find a tiny, little corner in my brain to stash this information, in case I need to impress somebody with my knowledge of Ornithology. I'm 75, and I have already forgotten where I put my glasses!

I'm sure it gives them better vision of what's under the water, but may also prevent fish from fleeing if they feel safer in the shade? idk The repeated stepping from spot to spot seems like it would chase away the fish.
