My friend just told me of a terrific website for US birds. The Birds of North American- Online, put on by the Cornell Lab of Ornithology, http://bna.birds.cornell.edu/bna . It is just $42.00 a year. Part of learning to photograph birds is learning their behavior, habitat, sounds, etc. Every little bit that you can learn about your subject will help you anticipate their actions which in turn gives you that much better chance to get that sharp, well exposed image you dreamed of getting. Hope everyone has a great Memorial Day weekend!!
