I'm not an expert, I know nothing about ornithology or biology or zoology or wildlife science or animal behaviours or animal intelligence, but sometimes I think about the fact that birdwatchers in Toronto observed a raven learn how to mimic crow calls, make a nest with a crow and raise a pair of crow-raven hybrids the birdwatchers referred to as cravens and I just think. That's gotta be love, baby.
