Constraint and innovation in color evolution among species and among plumage patches in five avian radiations
C. Eliason, R. S. Marcondes, M. D. Eaton, R. Maia, K. J. Burns, A. J. Shultz
The paper analyzes color evolution across five bird clades, finding that new color mechanisms enable new color space occupancy but not increased diversity, and that interpatch variation diverges from interspecies trends in males.
