Conférence « L’oiseau bariolé : enquête en forêt Amazonienne »

By Serge Berthier

Bird colors are highly varied, and may be due to pigments, microscopic structures, or both. They have essential functions, such as communication or camouflage, and can change naturally with the seasons or stages of life. In Amazonia, humans have developed tapirage, an ancient art that allows feathers to be voluntarily altered in color, a process still poorly understood despite its description since the time of the conquistadors. This talk explores this mystery, from the Amazon jungle to the Moche pyramids of Peru, and presents a recently-discovered source of color: fluorescence.
