Near Lavalle, in eastern Buenos Aires, the species had been ex- 

 terminated on the fertile, pastured uplands, but was common in a 

 desert stretch of sand dunes lying parallel to the beach below Cabo 

 San Antonio. From November 3 to 8, while camped in a small 

 hut in this region, I found the birds in comparative abundance. For 

 two days during a tremendous storm the tinamou, discouraged by 

 the downpour of rain, were entirely silent, but later when the 

 weather cleared after the temporal they sang from all sides. By 

 following the note it was usually simple to locate a pair and by 

 startling them to force them to wing. The flight is swift but heavy 

 and direct, so that they are easily killed. At this season they were 

 breeding, as females taken contained eggs ready to lay. 



While crossing on a train near Sierra de la Ventana on November 

 21 I noticed a number of pairs walking quietly about in the bunch 

 grass that covered the pastures. On December 17 near Carhue I 

 heard several calling from growths of thistles below the crest of 

 a hill, where the birds were sheltered from wind, but though the 

 musical, somewhat labored calls came from near at hand, the tina- 

 mou retreated through the dense growth as I advanced, and I did 

 not catch sight of them. On March 3 and 4, 1921, the species was 

 heard calling at long intervals near Guamini. It is said that these 

 birds can not compete with the crested tinamou, Calopezus elegaTis^ 

 so that when the latter invades a region the rufous-winged bird 

 disappears. 



In Uruguay the note of the rufous-winged tinamou was heard 

 on February 2, 1921, at the Bahado de la India Muerta, south of 

 Lazcano, but none were seen. 



This tinamou is hunted with dogs, and it is claimed that after 

 the bird makes two or three flights it is exhausted and may be taken 

 by hand. Be this as it may, I can testify that the initial flight is 

 vigorous. The flesh of the rufous-winged tinamou is white in 

 color and delicious in flavor, far exceeding in taste that of the other 

 species that I encountered. The bird is so heavy that the tender 

 muscles of the breast are frequently split as it falls to the ground 

 when shot. The caeca of this species are long, slender, and cylin- 

 drical in form, entirely different from those of Calopezus.
