A group of ~10 American White Pelicans from a previous trip many years ago to J.N. Ding Darling NWR in Florida. This was taken with one of my favorite lenses, the Sigma 300-800mm f/5.6. It was a Great Lens to setup on a tripod and work an area. At ~13 lbs you had to use a heavy tripod but you could really get a great assortment of images when you found an area where birds were coming and going and interacting with each other. It even worked well with 1.4x & 2x telconverters for even more reach. This image was taken with a Canon 1D mkIV @ 648mm. I have since replaced it with a Tamron 150-600mm which you can easily handhold for images and easier to carry. Plus it also works well with Teleconverters for more reach.
