This is the common Thryophilus of the highlands and Pacific slope, 

 being found on the upper Caribbean slope from 3,000 feet upwards, over 

 the whole of the plateau region, up to about 7,000 feet, and over the whole 

 of the Pacific slope to sea-level. I was surprised to find this species very 

 abundant in the vicinity of Buenos Aires, inhabiting low shrubbery, 

 especially around the borders of the "sabanas." It is not a woodland 

 bird, but wherever found is always in thickets and clumps of low scrubby 

 trees and along the roadsides. They are noisy birds, chattering and scold- 

 ing a great deal, but well out of sight. The song is loud, but not very 

 musical. I have not seen the eggs. Mr. Cherrie gives some interesting 

 notes on the habits of the bird (Auk, 1891, 275). 



The birds from the Terraba Valley are somewhat intermediate between 

 T. modestus modestus and T. modestus elutus Bangs, of Chiriqui and 

 Panama, but are nearer to true modestus (cf. Bangs, Auk, XXIV, 1907, 



305).
