Huge mystery grey / black ducks

Hello

I’ve been spotting these mystery birds sporadically since the summer on my local stretch of the Thames.

They’re about goose size, orange legs, yellow/grey bills. Dark grey feathers with white chests and black necks and heads. The photos show them having a sleep but when they’re stood or swimming they look like a mallard shape, just treble the size.

At first there were just the two who’d be found happily swimming around with the other mallards. In these photos (taken last week) it looks like they’ve had a chick! The third bird is dark dark brown, fluffy looking and the size of a regular mallard.

What on Earth are these lovely birds? Feeling like Charles Darwin on Galapagos right now, I’ve searched online and in every book I’ve got and can’t seem to find a name! Would appreciate any tips

  • Possibly in the 'Manky Mallard' category ... wait for an expert to point you in right direction!

  • I think these are a domestic breed known as Swedish Duck or Swedish Blue. You can read about them HERE

    Wendy is correct that these weird and wonderful domestic ducks are rather unkindly known as "Manky Mallards" because they have been selectively bred from the humble wild Mallard.

    I think you’re right! That’s the first time I’ve seen a picture and thought “that’s them!”

    At first I did wonder if they were a muck duck, but the size made me think otherwise.

    Thanks so much to yourself and Wendy for the tips! I‘ve got several pals waiting with baited breath, they’ll be pleased to hear the mystery is solved

    A little disappointed I haven’t discovered my own duck breed.... I think the Georgie duck has a good ring to it

    Yes, Anas platyrhynchos georgie would sound good. LOL
