I'm on the side of the Grey Tealists - for me, the head is too square, the beak too short and not quite tapering enough, the neck is not as thin and long in any of the photos as I would expect. As Ed mentioned, the eye is also the wrong colour. A major point for me is that while the tail does look pointed, the pattern of how the feathers are arranged looks wrong - in Northern Pintails, the central tail feather is clearly longer, while this looks quite different. I think it's just the lack of flight feathers that's really accentuating the tail.
Overall, I'd say Grey Teal.
As Nikolas said, hybrids are well-studied in northern ducks, but new and interesting ones are always popping up as ornamental ducks escape and start interbreeding. If I wanted to be facetious, I'd ask if there were any free-roaming Yellow-billed Pintails in the area, as the plumage and tail are a little similar...
Cheers,

Tony

Hi all,

I am also one of these Northern Hemispherians, who have seen tens of thousands of 
Northern Pintails in Europe, North America, Africa and Asia. Confirming others, neither 
jizz, plumage colour nor bare part colour "make it" a Northern Pintail or any 
of the other pintails. The jizz clearly indicates one of the teals - the only ID 
contenders are Grey Teal, Sunda Teal or Chestnut Teal and - if you want to stretch it - 
Cape Teal. To me the bird still looks like a Grey Teal.
The infamous "H" word is however not so infamous in Anas, Aythya, Anser and 
Branta. However, most Northern Hemisphere hybrid combinations appear to be well-studied 
and I cannot find any that looks that similar to Grey Teal as David's bird. As so often, 
the Southern Hemisphere is not so well covered in many studies. So, I still can't rule 
out a hybrid 100%. But again, I still think it is a Grey Teal.

Cheers,

Nikolas

With reference to David Taylor’s very interesting question about the ‘strange’ duck he 
saw on the University of Queensland campus out there at Gatton in the Lockyer Valley in SE Queensland (an 
area which was devastated by, unprecedented in white man’s time, floods last year) I would like to 
ask a question with the following context in mind.

Although I have been birdwatching for nearly 40 years I have never come to grips with moult. Although I have been 
photographing birds for most of that time and some of the most expert people in Australia have been very patiently 
trying to educate me in the understanding of moult I seem to be too dumb (or too old) to take it all in. 
I’m tempted to give those people names but I really shouldn't embarrass them so I won’t. But I say 
to them “Don’t give up.” I love youse all.

Anyhow..........
The question is:
Why is David Taylor’s ‘strange’ bird not a Northern Pintail female undergoing moult of 
the primaries and, possibly, the secondaries – as has been suggested?
Is it because it is in Queensland? (Oh, that is facetious, Bob and should be 
struck from the records).

I have not yet seen a pintail of any description so I am clutching at straws here but I have consulted 
“Wildfowl” by Steve Madge and Hilary Burn as well as HANZAB (we all know what that is, don’t 
we?). Having done so it seems to me that there is a possibility, small though it might be, that David, et all, has 
found something very ‘interesting’.

Why isn’t David’s bird a Northern Pintail female undergoing moult of the 
primaries and, as it has been suggested, the secondaries?

In asking this question, I am hoping that those birders who have had extensive 
experience with observing Northern Pintails will respond. After all, the majority of 
Australian birdwatchers with experience of northern hemisphere birds come 
from...............the northern hemisphere. At least that is my observation. A few 
Australian boundary-ed birdwatchers probably only see one or two Northern Pintails in 
their entire life. As I said, I haven’t seen any and I confine my observations 
to the mainland of Australia.

I realize the shortcomings of digital photography (having been involved with it for 11 years) and therefore I 
understand why David’s images vary in the colours of the plumage of this bird but, understanding those 
technicalities, I can see, as David saw, that this bird is ‘different’ to the average Grey Teal. My 
initial reaction was that it is always wise to not look for a rarity and to simply look for an aberration when 
observing something which looks ‘different’. My experience at that location is that the common ducks 
include Grey Teal so that is what I initially advised David . However, further consideration encouraged me to 
suggest that this bird might, only might, be something else.
As I read it, David’s bird might have a rufous wash over the head and the iris 
might be somewhat different in colour to that of Grey Teal. If so that could indicate 
Northern Pintail female.
Not Northern Pintail juvenile as the plumage is quite different.

In the course of education (of me in particular) I would like those birders who have 
had experience with Northern Pintail females (from an observer’s point of view) 
to come forward and voice an opinion.
Is that too much to ask?

Please understand that I am not being critical of anyone but simply wanting to 
ensure that an opportunity is not missed.
I don’t mind if I am proven to be way of track here.

A ‘proverb’ from the latest book I am reading “In advising a friend, seek to help, not 
please”. (The good Book – a secular bible- by AC Grayling)
