Bird project we have collected a large amount of sequence data

number of projects focused on the theory and practice of phylogenetics
and other organisms.
NSF support for the Early Bird AToL project is now complete, a number of participants in the project (Edward Braun, Michael Braun, Rebecca Kimball, Sushma Reddy, and Frederick Sheldon) remain committed to maintaining this web page and using it to disseminate information about avian phylogeny to the scientific community and the public.
