The little known of this species in the Republic at present is sum- 

 marized in the range above. The few specimens on record include a 

 male from Cricamola, taken in April 1937, by H. von Wedel (in the 

 Department of Zoology, University of California at Los Angeles), 

 1 (sex not known) taken by McLeannan at Lion Hill, Canal Zone 

 (in the American Museum of Natural History), a female secured by 

 Festa, at Punta de Sabana, Darien, August 1, 1895 (in Instituto e 

 Museo de Zoologia, University of Torino), and 1 prepared by W. B. 

 Richardson on the Rio Capeti, Darien, on May 26, 1915. In April 

 1947, at our camp where the Rio Imamado joins the Rio Jaque I heard 

 the harsh calls of these birds on several occasions. The Choco Indians 

 here knew them, but in night hunting I was not able to secure one. I 

 believed that I saw their eye shine from the high forest crown in the 

 tallest trees, but was never certain. They were reported in February
