The liver is darker than the kidneys possibly because of the higher content in deoxygenated blood, bile pigment, and lipofuscin (discussed in the "Lipochromes
" section) (Figure 2, D and H).
However, through a complex series of HPLC studies of the red feathers in 44 species of parrots (of more than 350 total species, 80% of which have red plumage), McGraw and co-researcher Mary Nogare found a unique set of five molecules responsible for the red coloring in the feathers, called polyneal lipochromes
, or psittacofulvins.
