I think the elongated brownish feathers with black central stripes draped across the back are a give-away here...

Hm. I was going to say male Gadwall, but after reading David's post, I took a closer look at those brownish feathers, and now I don't know. Northern Pintail, maybe?

Hahahaha, that made me laugh, David.

Adrian, the benefits of a mis-spent youth packed off to a British boarding school studying Latin up to my 'A' Levels! (Didn't really do me a lot of good then as my first escape from the "system" was to join the Royal Marines!)

Ah. I had no idea what the joke was, but with the followup about Latin I think I've figured it out: strepera vs. acuta, right?

A meta mystery (at least for me). :-)

You're right John- presumably when one was naming the Gadwall, the "raspy reb" (Cornell) or the "short 'nheck' and a low whistle" (Ducks Unlimited) was enough for Gesner to call it a "noisy duck", Anas strepera, although I understand that it's quack is just like a Mallard, only more frequent?!

acuta must refer to the "sharp" tail for the Northern Pintail, Anas acuta
