I think this is two mallards but can't be sure of the black duck
No interactions present.
I think this is another mallard hybrid, although it is possible it's a melanistic form.
If you google "mallard hybrid", you'll find several sites with photos of the various crosses out there. Mallards clearly aren't choosy...
All four ducks in the photo are Mallard 'mongrels' with genes from domestic breeds.
Personally I would stay away from using the term 'hybrid', which to me implies that they are crosses with other species (many ducks do sometimes breed with other species).
Try this web-page: http://10000birds.com/manky-mallards-domestic-feral-or-just-plain-odd-ma... (+ a link near to the bottom of this one takes you to a page dealing with Mallard hybrids).
Thanks for the web link: I knew that mallards were the ancestors of our domestic ducks, but I didn't realise that Indian runner ducks came from the same source!
Just realised I'd added a similar comment to another "manky mallard" shot:
'Hybrid is a term that can also be used for crosses between "populations, breeds or cultivars within a single species". But you're probably right that it's best avoided for situations like this. The term "manky mallards" isn't half bad!'
