Well, I think it was a duck, but I'm not even sure of that. Twice this month I've seen a water bird sitting alone in the middle of a small pond, mottled brown in color, smaller than a mallard and quite shy. Both times this bird has dived straight down. I patiently wait and wait and wait and wait, and the bird never reappears! Logically that can only mean that it dove down, swam to the rushes and then resurfaced where I could not see it.
Anybody have an idea what bird that might be?
I need a bird-identifying buddy!
