This is the common thrush of Costa Rica, ranging over the whole of the 

 country up to at least 8,000 feet, except the lowlands of the Caribbean 

 below 700 feet. It is not common nor a regular resident on the lowlands 

 of the Pacific, but specimens have been taken in several places at near 

 sea-level. On the Caribbean lowlands it was fairly common around 

 Guapiles (800 feet), but with the exception of one or two pairs I never 

 saw it below that point. It reaches its greatest abundance on the central 

 plateau, among the farms and coffee-plantations of that region. Its song 

 is pretty, much resembling that of our Robin, P. migratorius, and like 

 that bird it is found about the houses, gardens, and farms, more than in 

 the less settled districts. 



I took a nest on the Volcan de Irazu, at an altitude of about 8.000 feet, 

 on April 16, 1902, w T hich contained three badly incubated eggs. The 

 nest is large and bulky, made of moss and mud and lined with roots and 

 grass. It was placed in the thick top of a tree about thirty feet from the 

 ground, and just beside a house. The eggs are pale blue, very thickly 

 speckled, spotted, and blotched with chestnut-rufous, heavier about the 

 larger end, and mixed with a few lilac markings. Measurements: 29.5 X 

 22; 30.5X22; 29X22 mm.
