Good bird photos for my screen saver

I was able to download some great images of birds from the Audubon site to my iPhoto which I used to make a slide show screen saver that I really love. I have looked around on the internet for other sites but when I download them, the images do not have enough resolution and I can't use them. I love the 20 or pics that I have but would like to have more of the birds that I really love for variety. I did find out that there are screen savers like this available...just not for Macs. Any ideas?

I know if you join some sites like Webshots (not pay) they should have some nice bird shots by their pros.

There's also some good ones on wiki commons if you search for them, and they're all licensed for free use. You'll need to use the scientific names for searching.

Most sites that have copy righted photos make sure their photos are low redolution to keep people from using them.

Thanks everyone! Hey, Resin.....I looked for the wiki commons on my safari and the search engine didn't find it. Do you have the URL?

That aside, I am becoming more motivated than ever to get a decent camera and use my own!
