So if you live in England you’ll know all about Red Squirrels and their shockingly sad decline at the hands of the tougher and nastier American grey squirrel. Now in what shoddy journalists would probably call ‘one of natures ironies’ Canadian black squirrels are pushing out the grey in Washington DC (reg reqd). As this handy infographic shows they’re spreading all over the Washington area.

In 1902, and then again in 1906, the zoo got black squirrels from “the department of crown lands” in Ontario.

So what they’re essentially saying is that the British Monarchy was playing a long game of tit for tat genetic retaliation. Impressive.
