This Spiral communicates two main points: birds descend from dinosaurs, and dinosaurs too had feathers.

Bird phylogeny is a field in tremendous debate, and after much research the information that the "modern bird" section of the spiral was based almost exclusively on the paper:
Livezey, B. C., & Zusi, R. L. (2007). Higher-order phylogenetics of modern Aves based on comparative anatomy. Zoological Journal of the Linnean Society, 149(1). Retrieved in 2009. doi: 10.1111/j.1096-3642.2006.00293
