Duck ID please

I photographed this duck yesterday in the wildfowl collection at Regent's Park, London. The only thing that looks close is female Long-tailed Duck, but it doesn't look quite the same. Can anyone confirm?

Thanks for your help

[Picidae]

Looks ok for a female LTD in winter->spring plumage to me (males retain long tail and have more extensive white on head in winter->spring)

Yep its a long tailed duck, they have a few in the collection there along with quite a few other cool species
