This was a very helpful exercise. Good use of the Macauley library photos. Definitely helped me realize i want some more zoom capability in my next camera (current one only goes up 152 mm). I want to be able to take good, clear photo's of birds at my feeder, and at my local parks, and when I go on birding outings, such as to Cape May, NJ. Not trying to win awards, but just be out in nature and capture it and share it with friends and family.
