I'm one half of the Bird Nerds Team; the photographer; and helped build the website.
500px is a Canadian photo sharing site that has a very nice layout and features a lot of incredible artists.
The original photo sharing site for pros. I don't know if it's still used.
Links to creative geniuses; some of which I've been lucky enough to shoot with.
My favorite blog featuring work by Sean Bagshaw, David Cobb, Adrian Klein, Kevin Mcneal, Chip Phillips and Zack Schnepf (or bascially my top 6 favorite nature photographers).
Paul is a great guy and completely legit when it comes to nature photography. He carries a camera in one hand and an ice axe in the other and photographs some hard to get to places.
Dan Jurak is one of my photography heroes. He is a talented photographer that hangs out on the prairies and the frequency of his updates in unmatched.
