I captured this image of a Anhinga at Circle B Bar Reserve in Polk County, Florida. The bird was perched grooming it's feathers stopping to make a gurgling sound in between feather care. Not sure why Anhinga make that sound but the males always seem to do it when perched. Sometimes if you mimic the sound they will do it in return. Comments and critique welcomed and appreciated. Thank you for viewing.
