Carriker : List of the Birds of Costa Rica. 885 



quite, as blue as some of the birds from Panama, but none of the Costa 

 Rica birds are as bright as some of the Panama specimens. 



This species has a wide range, covering the whole of the Caribbean and 

 Pacific lowlands up to an elevation of not more than 2,000 feet, being more 

 abundant below 1,000 feet. It is fairly abundant throughout its range 

 and is almost entirely confined to the heavy forest and dense jungle. The 

 birds are inclined to be rather noisy at times and are usually seen in pairs. 



The only nest observed was taken at Cuabre, Talamanca, March 5, 

 1904, and contained two slightly incubated eggs. The nest was made 

 of brown weed-stalks and rootlets, lined with fine weed-fibres, was very 

 thin-walled and in general construction much resembled that of Zamelodia 

 ludoviciana. It was placed in a small shrub about eight feet above the 

 ground in a thick part of the forest near the river. The eggs are pale 

 bluish-green, speckled and spotted with lilac and chestnut, more heavily 

 about the larger end, forming a cap. Measurements: 23X16; 22X16 

 mm.

 Bangs Collection: Bolson, December, 1907 (Underwood). 



The only record we have for Costa Rica, outside of the Pacific coast 

 region, is that of a bird taken at Tres Rios by Boucard, who found it dead. 



Cherrie found it fairly abundant in the Terraba Valley and Underwood 

 secured a good series at Bolson, on the Tempisque River, during December, 

 1907. Through all my collecting on the Caribbean lowlands I have never 

 seen or heard of the bird there.
