I’m sure this is Bella, the juvenile from last years breeding season. I watched her catch a fish and then, to my infinite joy, she brought it over to within a few feet of me and ate it.
Ospreys are unusual among raptors for being piscivores. Their diet consists almost exclusively of fish. They are generally opportunistic, and will eat whatever fish species are accessible to them – either in shallow waters, or near the surface of deeper waters. They hunt for fish on the wing (less often from a perch), flapping and gliding 10 to 40 meters above the water.
