Honey, I can explain!

These two seemed to have a tiff that evening. The one on the right was sitting on the branch already when the other one landed with the fish. They proceeded to glare at each other and wave their wings about a bit, then the bird with the fish flew off.

I assume these two are the pair that has been hanging around the inner bay for a few years now, but not sure which is the male and which is the female.
