Turns out that these clever birds "Rooks" have been studied & are in fact quite smart. They figured out that by dropping pebbles in a tube it would elevate the water level thus in turn raising up a worm as well. It was pretty interesting.

I've always liked that crows love things that are shiny & pretty. Trully a girly bird at heart wouldn't you say? Plus one of my favorite movies is "The Crow." They also happen to be the perfect bird for Halloween which I so love.
I think a pet Rook would be rather fun.
