Research might have pinpointed
some of the genetic machinery responsible for the plumage colouration in
Audubon's and myrtle warblers, related but distinctly feathered North American
songbirds

Summary:
Birds get their bright red,
orange and yellow plumage from carotenoid pigments -- responsible for many of
the same bright colors in plants. But how songbirds turn carotenoids into the
spectacular variety of feathered patches found in nature has remained a
mystery. Now research might have pinpointed some of the genetic machinery
responsible for the plumage coloration in Audubon's and myrtle warblers,
related but distinctly feathered North American songbirds.
