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 graceful
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 February
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.

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 measurements:
Wing, 203.5; tail, 97.5; culmen from cere, 11; tarsus, 27.8
mm.
