I posted something similar on AGW some time ago...
Gentlemen, may I introduce you to
the Butcher Bird or "Würger" (verbatim: "Strangler")
A small bird of prey that sticks its prey to thorns in order to tear it apart. The reason for this behaviour is AFAIK the fact that the Würger lacks typical bird of prey talons and/or beak.
The word/name "Würger" in German has in no way the same sound/implication as its english translation and as lazs pointed out was indeed given to the plane by its creator, Kurt Tank. Also remember that very early versions of the 190 were considered undergunned by the LW since they only carried 4x7,92 mm. It wasn't until the A-3 (A-2?) arrived, that the 190 got the fearsome armement that *seems* to be the source of its nickname. Birds were often used as source of nicknames for german planes. Me-262 "Schwalbe" (Swallow), Fi- 156 "Storch" (Stork) or the He-219 "Uhu" (Owl) come to mind.
