There's green parrot type things near us too. My uncle (a farmer) thought maybe his milk was off the first time he saw them sitting on his roof. He couldn't believe his eyes...
Father-in-law had a very large eagle hawk sitting on top of his bird bath (what bird bath - it was gimongous bird), complete with the tethers that gave it away as being an escapee bird from a local falconer/or whatever they are called. As he couldn't get (wouldn't get) close to it, he just called the police and reported the sighting. Turned out it had already been reported missing.
A few months ago, I'm pretty sure I saw a vulture sitting on top of a motorway sign on the M4. Did a double take then, was worrying that maybe it was a sign (hahhahaha).
But seriously, from a lot of people being unresponsible, or having bad luck at keeping these species in there's now a load of odd looking birds (different from saturday night ones) flying about.
I've also spotted a panther in the woods near us too. Crazy! (We're in the UK - and anything larger than a hefty ould tom cat is rather alarming).
