Ijgj.g 31 jjj 1898, says they had spread over a radius of 50 leagues 

 from that city. At the present time they are found throughout the 

 settled central Provinces and are extending the area of occupation 

 rapidly. Mr. E. Lynch Arribalzaga ^^ reported in 1920 that they 

 had appeared about the church in Resistencia., Chaco, about 11 years- 

 previous, and I found them fairly common at Las Palmas, Chaco, 

 where they were said to have arrived about 1917. In traveling north 

 from Santa Fe I recorded them from the train as far as Vera, Santa 

 Fe, but did not see them again until I reached Resistencia. J. H. 

 Reboratti ^'^ notes that they arrived at Concepcion, Corrientes, about 

 1916. 



In Formosa they were fairly common, and I was astonished, on 

 August 21, 1920, to note a few about the railroad station at Kil- 

 ometer 182, the farthest point inland to which I penetrated along 

 the government railroad. It was an even greater surprise to note 

 a pair, on October G, in the little plaza opposite the railroad station 

 in Asuncion, Paraguay, where they were nesting in a hollow in a 

 tree. At the time I supposed this to be the first record of them for 

 Paraguay, but since have seen a statement by Bertoni^* that the 

 species has been seen in some numbers in the streets of Ascuncion, 

 since 1920. Bertoni cites a rumor that the sparrow' had been im- 

 ported from Buenos Aires on two occasions, but considers it probable 

 that it has invaded Paraguay of its own volition. The latter is 

 credible, as Passer at the time in question had established itself near 

 the Argentine frontier. 



English sparrows were common at Lavalle, Buenos Aires, and 

 one even appeared, on November 7, at a remote cabin hidden among 

 the sand dunes of the coast, 25 kilometers below Cape San Antonio. 

 To the south they were common in Bahia Blanca, and extended along 

 the line of railroad to the west as far as Zapala, Neuquen, at the base 

 of the Andes. Peters ^^ noted them in Rio Negro during 1920 and 

 1921 at Puesto Horno, Maquinchao, and Huanuluan, and I heard 

 rumor that they had spread as far as 16 de Octubre, in northwestern 

 Chubut. Bennett ^^ has noted their arrival in Port Stanley, in the 

 Falkland Islands, in November, 1919, as stowaways aboard four 

 sailing vessels from Montevideo. 



I found the sparrow common at Victorica, Pampa, December 23, 

 and saw it at Potrerillos, Mendoza, March 15, Tunuyan, Mendoza,
