Data.txt
	A tab delineated file containing the data for geographic distribution, molt timing, migratory status, mean time between molt and breeding (delta-t, in days),total number of carotenoids in a species' metabolic network, total number of carotenoids in the plumage, number of carotenoids that are fast or slow degrading and the elongation score of the metabolic network pathways (i.e., the maximum number of enzymatic steps between dietary carotenoids and those expressed in the plumage).
