This bird shows little resemblance to a flycatcher, either in appearance 

 or habits. I have never seen it except hopping about on the rocks in a 

 swiftly flowing stream, feeding upon the small insects upon the rocks. 

 It is quite tame and easily approached, but difficult to collect on 

 account of its always being in the midst of a rapid stream. I took an 

 adult female and an immature female in a rocky gorge at Ujurras de 

 Terraba, at an altitude of about 3,000 feet. 



It is apparently found over the whole of the country in small numbers, 

 wherever the conditions are suitable, that is, from about 800 feet upwards 

 to not more than 4,000 feet, but it is most abundant on the Caribbean 

 slope at about 1,000 feet.
