Family TURDIDAE. 

 Planesticus gymnopthalmus (Cab.). Bare-eyed Robin. 



We observed several of these birds at Guanoco and heard 

 their song. This closely resembles the song of our northern 

 robin with now and then a liquid phrase like that of the wood 

 thrush and an occasional sharp, metallic note. 



Planesticus phaeopygus (Cab.). White-throated Robin. 



One pair and an immature bird were seen in a clearing near 

 Guanoco. A sharp, robin-like alarm note was the only utter- 

 ance heard. Small beetles formed the chief food of this species. 



Family VIREONIDAE. 



Vireosylva chivi agilis (Licht.) . Northern Active Vireo. 



These birds preferred the higher branches of the dense 

 forest near Guanoco. In such places their song, a brief sweet 

 warble, would often be heard. Those secured were feeding on 

 small hymenoptera. 



Pachysylvia aurantiifrons saturata Hellm. Venezuelan 

 Pachysylvia. 



Not uncommon in the underbrush near clearings. The song 

 was a sweet vireo-like warble. In appearance and actions these 

 birds are very warbler-like. They catch small insects on the 

 wing and also search for them in the crevices of bark. They 

 were fearless, and in their excitement when pursuing insects 

 would come within a few feet. 



Family MNIOTILTIDAE. 



Seiurus noveboracensis noveboracensis (Gmel.). Northern 



Water-thrush. 



Every day which we spent at the pitch lake, we saw several 

 of these familiar birds walking and tipping along the edges of 

 the pools. 



Geothlypis aequinoctialis (Gmel.). Venezuelan Yellow- 

 throat. 



These handsome warblers, so much larger than our north- 

 ern yellow-throats, would occasionally appear for a moment at 

 the edge of the marshy thickets along the railroad track near 

 La Brea. In action they resembled their northern relatives, but 

 the song was less jerky, softer and more drawn out.
