We have ravens here they are smart as.We were watching Game of thrones a few months back and walked outside for a break to watch the sun go down and about a thousand you couldnt count them flew up a valley then circled us over head once and flew off,we were in silence watching them just been watching the crow tribe on GOT too The whole lot were following just a few,maybe even just one or two.Cant imagine where they'd been or where they were going ,we got hundreds round here noisy bastards but they also shut up and leave if I yell at them of go fitttzzz real loud at them.
