This GBH was actively hunting in this rapidly moving water. These are very common birds here in central Florida but I never tire of watching and photographing them. They are amazingly tolerant of people although I still exercise care not to cause them to give up their feeding and take flight. I was out trying out my "new" lens. I picked up a mint Nikon 70-300mm ED on ebay for $60.00. It's amazing the deals you can find. I previously bought a Nikon D1H for under $100.00 and this now gives me an outfit that I don't mind taking into the swamps and wetlands.
