CBS News brings us a story out of Germany about an eight-year-
old swan who fell in love with a big blue tractor. The swan,
appropriately named "Schwani", has been following around the
tractor for years.  Animal experts can't figure out exactly why
the swan feels such a strong kinship with a machine, but
suggested Schwani may have been exposed to loud, machine-like
noises when he was just a vulnerable young cygnet.
