Birds, yup...I've seen them do silly things like that. Blue Jays were notorious in our backyard for picking up shiny objects and flying away with them.
Grey Jays: notorious. In their nests you'd find: kleenex, buttons, coins, coloured strings, little toys, aluminum foil and candy, to name a few.
The pet cockatiel that I had posted: Sunshine. She loves picking up coins on the dresser and dropping them on the floor to hear them roll and make that 'pinging' sound.
Looks like a starling (the bird from the story). I have an entire wall of them beside where I live that live in the climbing ivy. Must be 100 of them in there.
Crows are also naughty, they'll steal watches and rings if left out. They'll take them to their nests and turn out to be worse than any burglar.
I still love the North American Grey Jay best. They are so personable, and will steal your sandwiches, and other non-guarded food. I have fed them dozens of times, and they still crack me up. Where I used to live, I'd whistle to one of them, and sure enough, he'd come down, perch on my hand, and dig into the peanut butter and jam sandwich. Or, beer nuts, he LOVED those.
Gotta love critters, great and small.
