It was an ordinary day for Harbor Master J.B. at The Harbor by the Bay.   He was walking the docks making sure the boats were secured, as he did every morning.  After a minute or two, J.B. realized he had company.  A rather large seagull had landed and was keeping pace with the harbor master down the dock. When Harbor Master J.B. greeted the seagull, he noticed there was something different about this bird.  It appeared there was something coming out of the bird's mouth.  J. B. was initially startled at the sight of the object. It must have been there a long while as whiskers had grown around it.  The seagull appeared to be in no distress, in fact, quite at ease.  Fascinated by this sight, Harbor Master J.B. sat down on the dock next to the seagull to learn more about this unusual bird. Can you guess what the object is?
