This wren is confined to the Pacific slope and lowlands, and has been 

 taken in widely separated regions, from the extreme southwestern extrem- 

 ity of the country to the Volcan de Tenorio in the north. It has also been 

 taken at two points near sea-level (La Palma de Nicoya and Bebedero) 

 as well as at a point near Alajuela (about 3,000 feet). However, it is a* 

 rare bird everywhere in Costa Rica outside of the higher portions of the 

 Terraba Valley, where it reaches its greatest abundance in the vicinity 

 of Boruca. It is a bird which inhabits low scrubby woodland or tangled 

 second-growth, and such conditions are certainly to be found in great 

 abundance in the immediate vicinity of Boruca, where it is found all 

 around the very edges of the village. 



It is usually to be seen in pairs, sometimes four or five together, 

 and is very tame and easily approached as a rule. It has a rather harsh 

 note and scolds and chatters a great deal, but I have never heard it sing.
