Bir.DS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 185 



clapping wincfs as I passed, or if at a reasonable distance watched 

 me alertly with jerking heads. The note of a wounded individual 

 was a curious, low, growling call. The display flight of the males 

 at this season was interesting. The birds sailed out with the wings 

 broadly extended, elevated at an angle above the back, and thrown 

 slightly forward so that there was a space between the tips of the 

 tertials and the sides. In this manner the pigeon described a grace- 

 ful curve to another perch or returned to the one that it had left. The 

 action was similar to that of the domestic pigeon under similar cir- 

 cumstances. A nest, found January 29, was placed at the border of 

 a little thicket on a small horizontal limb a little more than 2 meters 

 above the ground. This was a slight platform of grass, weed stems, 

 and little twigs, irregular in outline, and from 60 to 70 mm. in 

 diameter. An adult pigeon flushed from the nest, and in it rested 

 a young bird about half grown, with contour feathers partly cover- 

 ing the body. As usual in pigeons of this group, the incoming con- 

 tour feathers are deeper in color, and more reddish than in the adult. 

 Hairlike filaments of down that still adhere to head and breast are 

 chamois color. 



At Lazcano, farther north in the Department of Rocha, from Feb- 

 ruary 5 to 8, these pigeons were found in flocks of half a dozen 

 that fed in weed patches or rested in the shade of coronillo trees 

 in open pastures, or in dense thickets near the Rio Cebollati. A few 

 were recorded at Rio Negro, Uruguay, on February 15 and 19. 



NOTIOENAS MACULOSA MACULOSA (Temminck) 



Columba maculosa Temminck, Hist. Nat. Pig. Gall., vol. 1, 1813, pp. 113, 

 450. (Paraguay.) 



At Lazcano, Uruguay, the spotted-winged pigeon was found from 

 February 7 to 9, 1921, feeding in little flocks in weed patches, often 

 in company with Picazuros p. picazuro. The mottled shoulder of 

 the present species shows plainly in favorable light, and, with 

 slightly smaller size, is sufficient to distinguish the bird from its rela- 

 tive, which it resembles closely in form and habit. Two adult males 

 were taken February 7. One of these has the following measure- 

 ments: Wing, 203.5; tail, 97.5; culmen from cere, 11; tarsus, 27.8 

 mm. 



NOTIOENAS MACULOSA FALLAX (Schlegel) 



Chloroenas fallax S<eHLEGi!X, Mus. Hist. Nat. Pays-Bas, vol. 4, 1873, p. 80. 

 (Rio Negro, Patagonia.) 



The spotted-winged pigeon from central and western Argentina 

 is darker on head, neck, upper back, and ventral surface, and is 

 larger than what is assumed to be typical maculosa from the Rio 

 Bermejo, Argentina, and Lazcano, Uruguay. Chloroenas fallax as 

 originally described by Schlegel was based on a specimen said to
