very rapid flight of the l)ird northward ; the grain, 1 presume, 

 being picked up either in the southern or midland States of the 

 American Union. They are a very powerful bird on the wing. 

 Rising at iirst slowly from the water, they fly rather low for a 

 time, but soon ascend, and, forming a hollow wedge or V, with 

 an old gander at the apex;, continue for long distances before again 

 alighting. About the last of October they are generally all gone, 

 but I have heard of stragglers being seen even in mid-winter. 



BIRDS OF THE LOWER URUGUAY. 



BY WALTER B. BARROWS. 



( Concluded from p. 2y8.) 



184. Charadrius virginicus Borkh. Chorlo (Plover) . — 

 Seen only in the neighborhood of Bahia Blanca and the Sierra 

 de la Ventana from February 8 to March 19. During most of 

 this time it was abundant in flocks of twenty to two hundred 

 individuals, and for the first week or two all the larger flocks were 

 moving pretty uniformly in a south or southwesterly direction ; a 

 fact which I could account for only by supposing that the plains 

 of Patagonia must ofler some strong attraction in the way of food 

 at this season. 



185. Eudromias modesta {Licht.). Chorlito (Little 

 Plover). — Taken but twice at Concepcion, viz., April 29, and 

 May 6, 18S0 ; while a few specimens, either of this or the fol- 

 lowing species, were observed on the pampas during March and 

 April, 1 88 1. 



186. iEgialitis falklandica {Lath.). — One specimen, Con- 

 cepcion, April 30, 1880, and the doubtful observations mentioned 

 under the preceding species. 



1S7. iEgialitis collaris {VieilL). Chorlito (Little 

 Plover). — Rather abundant at Concepcion in March and 

 August, in small flocks all over the open country. Probably a 

 few winter there.
