BB: If you have chance, I would also recommend the ornithology center at Cornell University in Ithaca, NY. I was very impressed in my brief visit there. It is one of the premier bird research facilities in North America. The agriculture school also keeps/breeds several birds of prey (eagle, falcon, peregrine, etc.).

On a separate note, I remember way back when Microsoft introduced a sound card, the .wav files it bundled also include bird sounds from Cornell's ornithology center.

Welcome back!
