As you probably know, the Audubon society does great work in conserving bird habitat and advocating for the environment in general. Did you know that you can buy birding binoculars direct from Audubon? For example, Maine Audubon has new birdwatching optics from famous makers like Zeiss, Bushnell, Leica, Swarovski, Nikon and more. Their site has excellent pointers on how to evaluate the products' field of view, light-gathering capacity, magnification, and fit, which means the binoculars' weight and shape as they relate to the size of your hand, and what you'll be using them for, such as birding while hiking or boating.
