I have a number of series captured of different birds feeding on the fly, like this Snowy. Not their usual methods, but I have photographed it before.
What makes it so interesting is the various gyrations these birds go through to make it work.

Above the Snowy is ‘trying’ to hover over the water as he grabs a very small fish. This poor guy is not built to hover.

He must move away quickly or else he falls into the water. This tidal pool is not really deep but a bunch of other birds are doing the same technique and heading straight for him.
Feeding in a watering hole is not easy for the birds, but a ‘party’ for any photographer that walks up to one.

Above is a quick shot taken of a ‘grab and go’ Snowy I just discovered.
Very funny.
