| Birds | Blue-winged Teal Anas discors    Copyright David Seibel, 2011 (#5023) | Send Comment Camera: Canon EOS-1D Mark IV Exposure: 1/1600 sec, f/11.0, ISO 2000 Lens: Canon 500mm f/4L IS + 1.4x II TC Date: March 31, 2011 Location: Quivira National Wildlife Refuge, Kansas, USA Description: A strong "tailwind" provides a rare display of the beautiful, intricately patterned individual feathers on this drake. The wind was so strong that it nearly blew the bird off its feet whenever it stood taller than a crouch in the shallow water.
