I've never seen this before. Seagulls hovered over dry land for like 15 minutes then one by one, landed but didn't seem to be eating anything. What explains this Behavior?

First it was orcas, then sharks, and then otters. Now the seagulls are acting weird. We may be at war with the other species and only we don’t know it. I can’t blame them for seeing us as a threat.
