Equipment: Canon 1D Mark IV with Sigma 150-600mm F5-6.3 lens at 562mm. The non-maximum focal length was chosen after reading that this lens is sharpest just shy of the 600mm mark. This lens does pretty well in good light, arguably I should have stopped down a bit as its DOF wide-open (F6.3 at the long-end) is relatively thin (see the out-of-focus tail feathers in pic #4). All pics were processed from the RAW file in Photoshop CS5.
All hummingbird shots taken at 1/500sec, F6.3, ISO 400 or 500. Its amazing how its color changes depending on the angle and lighting. All pics taken with with Exposure Compensation set to +1 to +1.3 on the camera body. Hummer pics are 50% crops (i was only ~10 feet away).

Since there were few flying birds, i was hoping this goose was going to take off (it didn't). 1/1250sec, F6.3, ISO 640, 562mm
