Backyard bird watching

[Raven]

i would imagine a circling seagull would indicate
that there's baitfish below or some fishy activity....
theres potential there....

and actually if you were out to sea and had a trained one
to find the fish for a reward they are smart enough to deliver

always got a kick out of those diving ducks that
were tethered that would go catch fish
and then reeled in by the master
