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 Vi- 

 cente, 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 ma- 

 terial 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 con- 

 struction 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
