Here’s a great example of a Parasitic Jaeger living up to its name. It was pestering the tern on the left until the tern dropped its fish in order to get away.
In the very next frame, you can see the fish being caught and subsequently gulped down by the jaeger. Some birds are just jerks.
The thing is, in the image taken before the first one, I can’t see the fish in the terns mouth so it must have already swallowed it and the spit it up to get away from the jaeger.
