Confined to the highlands and high mountains, extending down- 

 ward in small numbers on the Caribbean slope to 2,500 feet. It is most 

 abundant on the high volcanoes and in the higher portions of the 

 Dota Mountains and the Cordillera de Talamanca. Its range overlaps 

 slightly that of P. c. compressus on the Caribbean slope, but there is 

 a considerable gap between the two on the Pacific side. It is found 

 only in the heavy virgin forest.
