Ellen Paul writes <That's the great thing about birds - you can just enjoy looking at them, rain or shine, heat or cold, in your backyard or someplace exotic, the first time or the millionth time...> Ellen, I`m with you all the way on that one. Thanks for the references re : Bird Songs. Folks @ Tri-State say some baby birds have innate song learning ability, other sp. ( they weren`t sure which ones ) had a critical period for learning. I`m having fun with it, at any rate, no fears that you discouraged me. Leslie Fisher North East Md Cecil Co
