Salisbury: Seagulls camp out in the parking lot at Salisbury Beach State Reservation on Thursday afternoon while waiting for the tide to go out so they can attack the mussel beds at the Black Rocks in the Merrimack River. The gulls pick up the mollusks and drop them on the pavement to crack them open. Summer time they spend thier time looking for beach-goers lunch scraps. Bryan Eaton/Staff Photo
