It was interesting to see this tree full of Roseate Spoonbills surrounding this White Ibis. The featured image was captured with a Sigma 300-800mm lens @ 800mm. It seems to be very helpful at J.N. Ding Darling to have a long zoom lens with a long telephoto zoom range. Many photo opportunities there are quite far in the distance. So instead of severely cropping your image you can frame a nice pleasing image to fill the frame with your subject. The Sigma 300-800mm lens was a huge & heavy lens and with a camera body was about 12 lbs. Add a Wimberly gimbal head & heavy duty tripod and you basically setup in an area and just work that area for a while. That is why I usually also carried another camera on my shoulder strap with a 400mm DO lens for faster moving subjects that flew close by.
