I found this great book at Amazon, Kindle edition: A Beginner's Guide to Photographing Backyard Birds: 12 Tips for Improving Your Birding Experience and for only $2.99, it's a steal!
It's a book about how to get great pictures of birds from your backyard, but I got so much more out of it! There are many photography tips that apply to all types of photography, not just birds.
It's well worth your time to check it out!
