Many thanks again to all that have responded and its always good and imporatant
to chew the fat on these things - Ive had some private messages as well as
those on this forum with some excellent feedback and I do beleieve we can say
that this bird isnt a Pintail and is almost certainly a Grey Teal albiet one
with a difference! My hunch was always Grey Teal hybrid but its been good to
get others perspective on it. My moment of extreme excitement at the pond is
hopefully understandable!
Happy birding all and thanks once again
Thanks also to Geoff Brown from Lithgow who was with me for his feedback,
advise and images.
Particular thanks to Bob Inglis for his research and comments.
cheers
