One of the more interesting developments in bird watching in recent years has been the nestcam - video cameras trained on birds' nests that allow us to watch the bird's family life unfold. This is Nature, so it isn't guaranteed to be pleasant, but it is fascinating.
One of the most popular of the birdcams currently operating is trained on a Bald Eagle nest in California. The eaglets are expected to hatch by March 31. Click on this link to watch the eagles hatch.
