SETOPAGIS PARVULUS (Gould) 



Cupriuiulgus jjomilus Gould, Proc. Zool. Soc. London, 1S37, p. 22. (Parana 

 River near Santa Fe, Argentina.) 



Near the ranch at Kilometer 80, behind Puerto Pinasco, Paraii:uay, 

 these goatsuckers began to call suddenly on the evening of September 

 17, 1920, and it was supposed that they were migratory as none had 

 been recorded previously. On the following night, by means of an 

 electric headlight, tAvo of the nocturnal songsters w^ere taken, so that 

 their identity was established beyond question. Their song resembles 

 you cheery chu chu cliu chu chu chu^ the first two notes uttered in a 

 clear tone and the rest forming a bubbling, rattling trill. They 

 called from leafy trees in open pastures, or from the forest, or came 

 out to rest on the limbs of fallen trees along the borders of the monte, 

 •or in paths cut among the trees. Here the headlight caught their 

 eyes with a reflected glow of deep burning red, like a coal of fire 

 but more intense in color, a beautiful object against the dark back- 

 ground. At intervals this light disappeared, apparently as the bird 

 turned its head, and then came into view again. Never more than 

 one point was seen at a time so that vision seemed to be entirely 

 monocular. The species continued its notes until my departure. 

 It was reco-ded September 23 at Kilometer 110, and September 24 

 and 25 at Laguna Wall (Kilometer 200). None were found at 

 Puerto, Pinasco, itself. 



In Spanish this species was known as cuatro cuero^ in Guarani as 

 uro-ooh^ while the Anguete Indians called it ka jee vay ta ta nee nm. 



For various reasons one of the specimens secured was preserved 

 entire in alcohol. The other, an adult male, seems large as it meas- 

 ures: Wing, 141.2: tail, 103; exposed culmen, 9.7: tarsus, 15.6 mm. 

 Comparative material is not at present available to decide the status 

 of this bird. 



The rictal bristles in this species are remarkabl,y short. 



HYDROPSALIS TORQUATA FURCIFERA (Vieillot) 



Caprimulgus furcifer Vieillot, Nouv. Diet. Hist. Nat., vol. 10, 1817, p. 242. 

 (Paraguay.) 



Specimens of this fork-tailed goatsucker from Argentina, Uru- 

 guay, Paraguay, and southern Brazil are distinguished from those 

 of northern and eastern Brazil by slightly larger size, and darker 

 coloration, Avith more buff on the abdomen so that the southern birds 

 should rank as a subspecies of 11. torquata. 



At Victorica, Pampa, from December 23 to 29, 1920, this goatsucker 

 was fairly common in low open forests of calden and algarroba, where
