Can anyone enlighten me on the pigmentation agents in bird feathers. Is
there a common class of compounds involved as in flowers and how is the
pigment distributed. Is it, for instance, homogenous within the relevant
parts of the feathers or is it surface deep only. I would be grateful
if answers could be emailed directly to kennjo.canberra.dialix.oz.au
since I might easily miss a posting to the list. Many thanks in advance
