Entrerios in January 1880 and December of the same year. Its 

 occurrence in Paraguay is also known to us, and Natterer obtained 

 examples of it in S.E. Brazil.

Resident, according to Mr. Durnford, in the province of Buenos 

 Ayres, " but probably, from its shy and retiring disposition, considered 

 rarer than it really is. Like our Nightjar (Caprimulgus europceus) it 

 frequents open spots in sheltered coppices on banks under a sheltering 

 hedge of thorns, and may generally be found in the same place from 

 day to day, coming out about dusk in quest of moths and other 

 insects." 



Mr. Barrows tells us that this species is not uncommon in Entrerios 

 in summer time, and " doubtless breeds." At dusk he frequently saw 

 it near the margins of the woods and thickets, where it makes only 

 short nights, soon settling on the ground. 



Gould's original description of this species was based on a specimen 

 obtained by Darwin near Santa Fe on the Parana, which is now in the 

 British Museum.
