I was very interested in rehabbing at one point, then realized that my time and money could be going to species survival, rather than survival of individuals.

If you would like, I can provide a list of references on song learning.> Ellen, Thanks for your informative response. Yes, I wold be interested in the song learning references. I`m going to ask some of the higher ups @ Tri-State what they know about released songbirds being able to join breeding populations. This is very interesting to me, and somewhat discouraging too. Thanks, Leslie Fisher
