The Costa Rican Dipper is found over the whole of the higher portions 

 of the country, but in small numbers. The lowest point at which I have 

 observed it was in the gorge of the Rio Sucio above Carrillo at an elevation 

 of about 2,000 feet. The bird seems partial to deep gloomy gorges, where 

 it frequents the rocks in the cold mountain torrents. 



I found one pair on a branch of the Rio Ceibo, high up in the mountains 

 above Ujurras de Terraba, where the stream came tumbling and foaming 

 down through a deep gorge. Their discovery was caused by first finding 

 the nest as I was climbing up a precipitous wall of rock beside a waterfall. 

 It was a rather flat, cup-shaped structure, built almost entirely of moss 

 and placed on a narrow shelf of rock on the brink of the falls. 



It contained but one partially incubated egg, which was blown, but 

 later misplaced, and lost, so that I cannot give its measurements. In 

 color it was plain dull white, of the usual shape and size of the Water Ouzel 

 of the United States.
