I can't remember where I found this, or even if I found it here.. Either way, I think this deserves it's own post.
Here is a list of a few links to some nest cams of wild birds around the world.

Some of these don't work, but I watch the osprey nest in Scotland. (It's on the first row in the center)

Barn owl, falcon and wood duck nests. (There's a 4, but the fly catcher babies are ready to fledge any day now)

This one goes straight to a barn owl nest in England.
If you choose to view, I hope you enjoy! I like having a few of these in the background when I'm working.
