The late, great George Gobel used to say "well, I'll be a dirty bird!" That was because he didn't know about scalbies. Scalbies are dirty birds as allyl isocyanide smells bad or Andromeda is far away. They are members of the crow family but crows don't admit it. They inhabit essentially uninhabitable desert areas around Omnia because competition can't survive. They eat anything. They eat things that thought they could eat anything and died from it. They are nearly flightless to conserve energy, since no predator will eat them or could survive in their habitat and their lunch tends to be dead already. They are described as looking like other birds after an oil slick.
