Resident. Found locally in the Subtropical Zone and the lower edge 

 of the Temperate Zone on Volcan Baru in Chiriqui. This inhabitant 

 of the higher mountain forests was little known among early col- 

 lectors. The first record for Panama was a bird in the Salvin-Godman 

 collection taken by Arce, labeled only "Chiriqui." This is listed by 

 Sclater (Cat. Birds Rrit. Mus., vol. 14, 1888, p. 236) and by Salvin 

 and Godman (Biol. Centr.-Amer., Aves, vol. 2, 1889, p. 83) without 

 detail except the brief description. It was first noticed regularly by 

 W. W. Brown, Jr., when from January to April 1901 he collected 

 18 specimens near Boquete and on the slopes of the volcano above, 

 at elevations ranging from about 1200 to over 2100 meters. These 

 were recorded by Bangs without detail other than locality, date, and 

 sex (Proc. New England Zool. Club, vol. 3, 1902, p. 39). Mrs. David-
