Please join the Biodiversity Heritage Library (BHL), the Smithsonian Libraries, and the National Museum of Natural History (NMNH) for a twitterchat on September 2nd, 2014. The chat will take place between 2-3 pm (EST) and feature Helen James, Curator of Birds and our recent Once There Were Billions exhibit in NMNH, and Martin Kalfatovic, BHL Program Director.

This September marks the 100th anniversary of the death of the very last passenger pigeon, Martha. In honor of the event, our chat will focus on Martha and the passenger pigeon, extinction and the importance of saving historic taxonomic literature through projects such as BHL. Folks will also have an opportunity to ask questions about Once There Were Billions, species survival or anything else on your minds about birds or biodiversity.

You can send questions using #Martha100 to @BioDivLibrary, @SILibraries, or @NMNH. Helen will be taking over the @NMNH account and Martin will man @BioDivLibrary to answer your questions. Everyone is invited to participate and follow the discussion by using #Martha100. If you’re not on Twitter, feel free to leave your question in a comment below or drop us a line by email at [email protected].
