This is about a new book on extinction -not necessarily avian but any species. I found the Q&A very interesting particularly because it is true that we seem to know (and care) more about some species more than others (birds not been an order that we seem to care much about) and, taking into consideration the Cites possibly addition of African Grays to the Appendix I, I thought you might like to know about it.
