Whats the Duck Sp on this checklist?

Why not a Female Mallard? Sure looks a lot like one.

It does, and yet it doesn't somehow. I've been scratching my head over this for a while, and I have yet to find a good match, until today. The bill and the scapulars were throwing me off. But, I'm fairly certain this is a Gadwall.

Mallard shows some scapulars with pale Buffy stripes down the center. Gadwall don't. This bird lacks them. The bill is slightly spatulate, compared to the relatively straight bill of Mallards. The bill color is certainly darker and messier than I would expect for a Gadwall, but it is within reason. The head seems pretty rounded, but Gadwalls can be sneaky...

I was tempted but I'm still not convinced. The head (almost always more square) and colour (typically plainer and more grey) doesn't look right and no hint of white on the secondaries in any of the photos (although this doesn't always show) plus it has white on the tail. OTOH it does have a faint eye arc.

I'm giving up on this one, it may be a Gadwall but I'm thinking another odd Mallard.

Of course Mallard x Gadwall is a possibility but I'm not sure about female examples.

Agreed. The bird doesn't feel like a Mallard, but than again it looks like one. Gadwall was my original guess, and still is.

I looked at MALL x GADW female photos on eBird (there’s only one bird) and it was similar but not quite right. Here:https://media.ebird.org/catalog?taxonCode=x00420&sex=female

Probably safe to assume they are under reported, especially in view of this thread, but considering the variability of hybrids.........

Wondering if the white on the tail make female Gadwall dubious?

I'm sticking with odd Mallard or quite possibly a hybrid (might be worth reporting this option).

Oh yeah, I’m sure there’s way more. They would be quite tricky to pick out. 
 

Also, female Gadwalls can have really pale rectrices especially from this angle. Just looking at photos on Merlin I see several examples.

At this point I will withdraw from the debate (should it be reported as a Gadwall?) and go back to my report for the day.

Didn't think about until now. What about a Blue-winged Teal? It would be rare, but seems like a perfect match.

I wouldn't exactly say perfect match. I've never seen a Blue-winged Teal with even a hint of orange on the bill, and it structurally seems wrong. At least not a pure BWTE, although it crossed my mind before.

I don’t think so. The bird in question doesn’t have strong eye arcs like a BWTE, and I second @Quiscalus quiscula‘s comments. Also, just FYI, BWTE are not rare at the location of the bird in question at this time of year.
