Meet F48269GB06 aka Buddy
"Buddy" here is a stray racing pigeon that landed at my window. I first didn't notice the rings on his legs, but then I understood why he was so comfortable with me and my camera inches from him (I even took macros).
At that point I looked up on the internet what to do with it (basically, feed it -no bread!-, give him water and let him rest). So I let him jump in, gave him some corn and a cup of water. After which he quickly found himself a dark corner to sleep, out of which he promptly came out to come and peck at my fingers whenever I typed too hard or fast. Haven't figured out why.
He flew away the next day.
Talking about straying : Buddy was a British pigeon and that pic is taken from near Paris !
