It seems fish might be more clever than we thought. I had seen videos of birds being eaten by whales (which aren’t, of course, fish), but it seemed clearly accidental (the birds were trying to eat the fish driven up to the surface by the feeding whales). On the other hand, in the video that this article offers it is quite clear that the catfish are hunting the pigeons and not accidentally eating them.
I also found it rather amusing, but then I don’t care much for pigeons.
