The bird survey portion of the Chattanooga BioBlitz will take place April 21-22, 2012 at the Chattanooga Arboretum and Nature Center (formerly Chattanooga Nature Center and Reflection Riding Arboretum). The area is typically has a good diversity of birds, and spring migration should be peaking around that date. If you are interested in participating, please contact me. Even if you do not wish to help with the bird survey, come out and what is happening! David Aborn Chattanooga, TN
