I found a fun sequence while looking through old Barnegat Light pictures: a second year Great Black-backed Gull getting ready to eat a small dead shark. Gulls are omnivores and will pretty much eat anything, including small sharks. Just type “daring seagull eats live baby shark” into YouTube if you want to watch a gull in action. The bird on the right in the two top pictures is a Herring Gull. The captions are what I imagine they were saying to each other :-).
