This is one of the rarest of the Central American Dendrocolaptidce, 

 not only in Costa Rica, but throughout its range. I know of but ten 

 skins in existence, of which three are from Panama and the remainder 

 from Costa Rica, one in the Salvin and Godman collection, one in the 

 Museo Nacional de Costa Rica and five in the U. S. National Museum. 



The bird is evidently confined to the higher portions of the country, 

 all those from Costa Rica having been taken from 3,000 feet upwards. 

 I know nothing concerning the habits of the birds and have never seen 

 it in life.

This species is confined to the mountains of the central portion of 

 the country up to at least 7,000 feet, extending down the Caribbean 

 slope to about 1,800 or 2,000 feet. It is not found on the lower slopes 

 of the Pacific, but only in the higher parts of the mountains where 

 humid conditions prevail, such as the high Talamancan Cordillera and 

 the Dota Mountains. It is found in the heavy forest, but keeps well 

 up in the trees, climbing up the tree-trunks and branches more like 

 the true Dendrocolaptidce.
