In south Georgia we called them removed Yankees... Out west they call them snow birds, but every bird I've met has had better sense... including the one that accidentally committed suicide on the side of the building.
Had the manager at the quarry the other day asking about my chickens, asked if I got brown or white eggs because he's raised both. I told him I get I get brown eggs, green eggs, and a blue egg. He told me to stop yanking his chain. I had to show him pictures online of EE eggs before he believed me.
The other day I let my neighbor hold Junior, who is the sweetest, most polite cockerel I have ever met. He'll just sit and perch on your arm for the longest time... likes to nuzzle in my hair too. The neighbor asks me "What sets him off?" "Sets him off?" says I completely confused. "Yeah, I don't want him to go crazy on me..." "Nothing sets that one off," I just smiled and shook my head.
