See something unusual about this duck? Looks a bit like female mallard? Maybe she’s got some resemblance but it’s not – it’s twice as big as mallard! I’ve spotted this one in one of the parks in Warsaw and was astonished. Can it be a new species I never heard about? Then I realized it must have been a hybrid of mallard and domestic duck. I knew the male mallards get sometime too horny during the mating season and they find attractive the female of any duck species, but I’d never before seen the results.
