Guan Horned (oreophasis derbianus) near endemic – Mexico

Rear view.  The Horned Guan lives in montane forest at altitude up to 3,350 metres. It  makes a variety of sound but this photo shows the voice box expanded producing a  low frequency booming uhmm, uh’mmm.  This sighting was so exciting and a special privilege to be in the presence of the endangered species.
