Replying to a message of Ardith Hinton to James Bradley:

 AH>          I imagine seagulls might, yes... they do eat shellfish.  They

There's a HUGE flock of seagulls that hang around a rest area on the shore
a couple of miles west of the Mackinac Bridge on Michigan's UP.  I have a picture
of one of them taking a french fry out of my hand - it's hovering above me about
three feet from the camera and pretty much fills the whole frame.
