MYOSPIZA HUMERALIS DORSALIS (Ridgway)
Cotumicuhis manimbe, var. dorsalis Ridgway, in Baird, Brewer, aud
Ridgway, Hist. North American Birds, vol. 3, 1874, p. 549. (Buenos
Aires.
)
)
This common form was encountered at Riacho Pilaga, Formosa,
August 8 to 21, 1920 (adult male, August 11) ; Formosa, Formosa,
August 23 and 24; Las Palmas, Chaco, July 15 to 31 (4 adult males) ;
Carhue, Buenos Aires, December 17 (adult male) ; Guamini, Buenos
Aires, March 6, 1921 (adult male) ; Carrasco, Urugua}^, January 16;
La Paloma, Uruguay, January 23 : Lazcano, Uruguay, February 2 to
Q (adult male taken) ; and Eio Negro, Uruguay, February 14. The
birds were found in weed or grass grown fields usually near but not
in marshy localities. They have the habits and mannerisms of the
grasshopper sparrows of the United States, but appear decidedly
darker in color. On the southern pampas they were found at times
in pastures with very little cover, Avhere they crept about on the
ground as inconspicuously as possible. During the winter season
they were entirely silent, but were in song the middle of February.
One taken at Guamini, March C, had begun to molt.
The Toba Indians called this bird po ko Ukh.
MYOSPIZA HUMERALIS TUCUMANENSJS Bangs and Penard
Myospiza humeralis tucumanensis Bangs aud Penard, Bull. Mus. Comp.
Zool., vol. 62, April, 1918, p. 92. (Tapia, Tucuman.)
An adult male, shot December 26, 1920, at Victorica, Pampa,
agrees in coloration with the type-specimen. At Victorica the birds
were fairly common on rolling hills covered with bunch grass. They
were breeding and were in song at this time.
PASSER DOMESTICUS (Linnaeus)
Fringilla domestica, Linnaeus, Syst. Nat., ed. 10, vol. 1, 1758, p. 183.
( Sweden.
The familiar house sparrow, or gorrion, is well established now
throughout the Argentine, where, according to Berg,^^ it was first
introduced in Buenos Aires by E. Bieckert in 1872 or 1873, for the
purpose of destroying a Psychid Oiketicus platensis Berg. Several
importations may have been made, however, as Doctor Holmberg-^
reports that they were brought in by one PelufFo, and Gibson ^"^
cites a rumor that they were introduced by a German brewer. Sparrows
first attracted attention in tlie nineties, as Gibson mentions
them on the Calle Florida, in Buenos Aires, in 1890, and E. L. Holm-
es Com. Mus. Nac. Buenos Aires, vol. 1, 1901, p. 284. See also F. Lahille, El. Ilornero,
