Distributed over the highlands and high mountains of the whole 

 country, from about 3,000 feet up to timber-line, but very rare below 

 7,000 feet. It is a true tree-creeper in its habits, climbing about on 

 the tree-trunks and limbs of the forest trees, and prefers the heavy 

 humid forests exposed to the moisture of the Caribbean winds rather 

 than the slopes leading down to the lower plateau region, which are 

 drier. Like so many species of the higher Caribbean slope, it is 

 abundant in the higher parts of the Dota Mountains and the Talamanca 

 Cordillera wherever they reach up to 7,000 feet.

The Costa Rican race of P. brunnescens is very distinct from the 

 Bogotan form and must be known by the name Lawrence proposed for 

 it in 1865, w T hich has possibly because of the lack of proper material 

 for comparison been universally ignored by subsequent writers (until
