2 74 Barrows on Birds of the Loivei- Uruguay. [J^'y 



i6i. Querquedula versicolor ( Vieill.). Patito (Little 

 Duck). — Resident at Coucepcion, where a few probably breed ; 

 but far less abundant in summer than in winter, when it is the 

 commonest and tamest of all the Ducks found there. We found 

 it abundant on the pampas wherever there was water. 



163. Dafila spinicauda {Vicil/.). — To this species I refer 

 with some hesitation a Dafila which was quite abundant at Cou- 

 cepcion during June, 1S80, and was afterwards met with several 

 times on the pampas (Arroyo Pigu6, March 23, 1S81 ; Puan, 

 March 38 ; Carhu6, April 6) . Unfortunately no skins were saved. 



163. Dafila bahamensis i^Llnn.). — A single specimen was 

 killed at Carhu6, April 7, iSSi. 



164. Mareca sibilatrix Poepp. — First met with near Bahia 

 Blanca in February, 18S1, when a few were observed — all moult- 

 ing. Two months later we found it abundant in all the streams and 

 pools of the pampas near Puan and Carhue. 



165. Spatula platalea {Vlelll.). — 'Only met with on tlie 

 pampas and in winter. In the salt lakelets of Puan and Carhu6 

 it was by far the most numerous of the Ducks, being often seen 

 in flocks of one to two hundred. 



166. Metopiana peposaca {Vlelll.). Pato (Duck). — A 

 Duck the size of the Mallard, and somewhat resembling it in 

 color and flesh. Very abundant on the Uruguay in times of 

 freshet and probably .a few breed about Concepcion, as they cer- 

 tainly stay there all summer. It was met with in greater or less 

 abundance at every point visited, and was usually found in flocks 

 of from ten to fifty individuals. 



167. Erismatura dominica {Lhtn.). Patito (Little 

 Duck). — Abundant in the streams of the pampas, associated 

 with Podlceps rollaizdf Coots and Gallinules. Usually seen in 

 small parties of three to six individuals, which rarely fly, always 

 dive at the flash of a gun, and spend at least half their time, when 

 undisturbed, under water. 



168. Columba picazuro Temm. Paloma del monte 

 (Wood Pigeon). — The largest and least comHion of the Pigeons 

 observed. Sometimes seen singly, but more often in flocks of 

 twenty-five to two hundred or more individuals Seen only in 

 woods in the vicinity of Concepcion. Most abundant in winter.
