This woodcreeper, largest of its family in Central America, 

 though found from southern Mexico to Veraguas in western Panama, 

 is known principally from the record of specimens collected. In the 

 northern part of its range south to British Honduras it is recorded 

 from forests of pine. Farther south it is reported from areas of cloud 

 forest in the mountains. In common with its family relatives it has 

 the strong feet, with sharply pointed claws, and rather long tail 

 with stiffened tip, which serve it in climbing the trunks of trees. 



Two geographic races are recognized in the Republic, differing in 

 depth of color.
