I captured this image at Circle B Bar Reserve in Polk County, Florida. My advise, if you see one of these birds, don't stop, don't raise the camera, run away from it quickly... an exposure nightmare. Maybe a overcast day might be better but then I fear it would be just a black blob, bright light is needed for the iridescence and colors to show. This image was captured about an hour after sunrise in the spring. Comments and critique welcomed and appreciated. Thank you for viewing.
