Martin Mere WWT stifftails

[Writhedhornbill]

What species of Stifftailed ducks does Martin mere keep?

I presume that they keep the white headed duck, but I remember Maccoa ducks. Does anyone know what species they keep?

I can remember seeing both those species on my last visit, about 10 years ago. I think they also had North American ruddy ducks.
