    Just checked it again and this is identical to the Photo in the Collins Guide that says it is a Green Winged Teal , the other Teal is a Blue Winged teal and it has got a Vertical white stripe in its head in front of its eye. behind that its head is Blue. Here is a photo of the page from my phone....

    Yes, That's a Common Teal or Eurasian Teal. Note the vertical white line on the flank of the Green Winged.

    Your're probably on a page for North American vagrants. The Common (Eurasian) teal and the Green winged teal (north american teal) are similar looking species. Your bird doesn't have a vertical stripe. The horizontal stripe (partly covered in your photo) is directly above the horizontal black strip on the body.

    As I said earlier , I have never seen one before so I have gone with the ID in the Published Collins Guide , The guide is of British Birds and there is no Mention of american visitors in the descriptions .

    Fair enough, but you have a common teal.

    Here's a link discussing the differences between the two:

    http://www.sibleyguides.com/2011/03/distinguishing-green-winged-and-common-teal/

    And here's the main giveaway, side-by side, essentially what is the North American version of a Teal (Green Winged Teal) on the left with a vertical white stripe towards the front, and our common (Eurasian) Teal on the right with a horizontal white stripe that is sometimes obscured by other feathers:

    Some people consider the green winged teal and common (eurasian) teal the same species. So occassionally people refer to our Common teal as green winged teal. Technically not incorrect.

    It's worth noting that the Irish Rare Birds Committee, the British Ornithologists Union and the American Ornithologists Union all consider them seperate species now though. To the best of my knowledge its only relatively recently they made their minds up on it, but they're the authorities when it comes to this kind of stuff. It's unanimous now.

    Kumliens gull is a good example. It used to be considered a subspecies of Iceland gull (Thayers's/Iceland gull hybrid species), but now it has full species status.

    Northern Harrier has only recently been accepted by the BOU as it's own species too; previously thought to be a subspecies of Hen Harrier:

    Don't think Kumlens is considered a full species only a subspecies of Iceland Gull...I could be wrong though.

    As far as I know the 'official' line is Kumlien's is a subspecies, although there is much debate on it.
