I've had fun watching this Osprey nest. Thanks V-Key for putting up the link.
Here is another one that I've been watching that came from a friend:

It is of a bald eagle nest in British Columbia. This is a live video feed all day long with sound. There were two eggs initially. One hatched, the other will not, but is still in the nest. It gives a reference to how the eaglet has grown. Three cameras give different perspectives as they switch from one to the other. It is amazing to see how quickly this baby has grown.
