Bird photography - resources from the archive

All these are analog ones, Velvia, Provia, Sensia... Yes, these were beautiful and hard times. I was trying bird photography for a years, but I felt all of the results as poor overall. Here is what I found in the deep archives which is possible to be shown on the page.Now with the raise of affordable phototelly's like Tamron 150-600 I purchased plus more systemtic attitude - I am hoping that the story will begin again.
