A Snowbird in Paradise

Now I ask you...look at these two photos and tell me...is that a baby that appears at the left part of the nest?

I am shooting with a Canon Digital Rebel with a 300mm lens on a tripod and with a remote shutter trip, but this nest is so far away this is the best I can do. I am searching for articles on the Internet about how to shoot these photos. I don't know of any way to do better without buying a longer lens.

This is the photo I was out there to try and shoot...the adult takes to the sky around 6:30 PM ET every night and it is awesome to watch...just kind of hard to catch. The tripod is out of the question following a bird on the wing.
