I'd often thought that Edgar Allan Poe must have been on some real drug bender to have imagined a raven saying "Nevermore". That is until we moved here. Those dang crows are as big as some of the wild turkeys, and are so loud, I don't wonder how Poe could have imagined that anymore!
I just had to laugh, I guess they are nuisance birds, but I just love crows. They are so bold, and some of them get huge!! I can always count on the crows to ~remove~ the wildlife roadkill Gypsy and I see on our walks.
Jays, Crows and Ravens are in the same family as Magpies, they are all great talkers, if slightly slower learning then parrots. That is probably why Poe used the Raven in his poem (Parrots would be much less sinister, IMHO)
Their close connection probably explains West Nile hitting them in the same way.
