BIEDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 433
March 23 to 29, and Tapia, Tiiciiman, April 6 to 14. Serie^^ has
noted its recent arrival at Amaicha, Tucuman.
At the Museo de Historia Natural in Montevideo I was told that
the sparrows of Uruguay were supposed to have come from an im-
portation made at Colonia about 30 years ago. Alvarez,^^ in 1913,
speaks of them as common throughout Uruguay, in corroboration
of which I noted them in fair numbers at San Vicente, Lazcano,
Corrales, and Rio Negro. E. G. Holt informs me that in 1919 they
w^ere established in the city of Rio Grande do Sul in southeastern
Brazil. (I saw large numbers in Rio de Janeiro, in June, 1920.)
Serie also reports them as abundant in Rio Grande do Sul.
The three preserved as skins were taken at Lavalle, Buenos Aires,
November 1, 1920; Guamini, Buenos Aires, March 5, 1921; and
Tunuyan, Mendoza, March 23, 1921.
SPINUS ICTERICUS (Lichtenstein)
Frmgilla icterica Lichtenstein, Verz. Doubl. Zool. Mus. Berlin, 1823, p.
26. (Sao Paulo, Brazil.)
Seven specimens are referred to the presnt species : A
male from
Dolores, Buenos Aires, October 21, 1920; two males from Lavalle,
Buenos Aires, October 27 and November 1; a pa,ir from San Vicente,
Uruguay, January' 2G, 1921 ; and two immature males taken
at El Salto, above Potrerillos, Mendoza, March 19. The last two are
in Juvenal dress and are identified tentatively as comparative material
of Neotropical s-pinus is not at this moment available. These
two are dull in color and have the under tail coverts striped with
dusky which suggests that they may be harbatus.
On October 21, 1920, three were observed and one taken on low
ground bordering a marsh near Dolores. In the vicinity of Lavalle,
Buenos Aires, the species was common from October 27 to November
13. On October 30, at Los Yngleses, a pair were busy Avith the construction
of a cup-shaped nest in a climbing rose near a door. And
on the following day another nest was begun 7 meters from the
ground in a pine tree. During the first week in November siskins
were noisy and demonstrative, and were continually flying about
with great display of the yellow markings in wings and tail, but by
November 10, with incubation begun, they were quieter and less
frequently in view, though the song of the male, a pleasant chatter-
ing warble, uttered brokenly and rapidly like that of a pine siskin,
w^as still given constantly. They delighted in feeding on the ground
on recently cut lawns.
Near San Vicente, Uruguay, the species was breeding commonly
in the great palm groves that grew in the swampy lowlands, and at
