It's late winter at Ding Darling National Wildlife Refuge on Sanibel Island, Florida. Many birds have finished nesting, and young birds are everywhere. This morning, wind and tide have conspired to strand schools of fish in backwater ditches. And the birds are taking advantage of it. It's a feeding frenzy!
