My late friend John Natterer informed me, when in London some thirty years ago, that this beautiful species, 
the Trogon aurantius of Spix, was not uncommon in the woods near Rio de Janeiro; we learn from August 
von Pelzeln’s “ Ornithologie Brasiliens, Resultate von Johann Natterer’s Reisen in den Jahren 1817 bis 1835,”
