Carriker : List of the Birds of Costa Rica. 711 



Similar to L. pileatus of southern Mexico and Guatemala, except that 

 the back is lighter green and the under parts much paler, abdomen prim- 

 rose-yellow. It is nearer to L. super ciliaris in general coloration than to 

 L. pileatus, except for the brown instead of gray cap. The single speci- 

 men from Tenorio is rather intermediate between the Boruca birds and 

 Mexican specimens, having the back dark green as in the latter, with 

 the lower parts pale like the type of the new form from Boruca. 



I can give nothing concerning the habits or habitat of this species, 

 more than that it is taken in the forest, like its near relative, L. super- 

 cilia ris.

I found this species only in the thick, dark, virgin forest on the mountain 

 slopes above Juan Vifias, where several were secured and where it was by 

 no means a rare bird, but very shy and difficult to shoot. It usually 

 perched near the ground, and at the slighest disturbance flew away for 

 fifty or a hundred yards before alighting again. It has been taken in many 

 localities scattered over a wide area, but always above an elevation of 

 1,500 feet, and from that up to at least 5,000 feet. 



From the conditions in which I found it, I would imagine it to be more 

 partial to the heavy, humid forests of the Caribbean watershed. Basulto 

 took it high up in the Dota Mountains and Underwood in the Cerro de 

 Santa Maria near the Pacific coast in northern Costa Rica, both of which
