188 Mr. Ambrose A. Lane — Field-Notes 



70. Ardea cocoi, Linn. 



This species is reported as a regular winter visitant to 

 Valdivia, the Rio Bueno, Pilmaiguen;, &c., and the Laguna 

 Llanquehui. I believe the natives call it the " Pillo/^ which 

 name is properly applied to the Maguari Stork. The 

 Germans call it " Silber-reiher " ( = Silver Heron). 



4- 71. Ardea egretta (Gm.). 



Ardea egretta, Sclater, P. Z. S. 1891, p. 135. 



(Sacaya.) 



This species ranges all through Chili, occurring even at 

 Sacaya. It is most numerous in the central provinces, 

 and not so common in the south. 



The note is harsh, but not often heard. These birds are 

 very wary. I have seen them on streams close to the sea- 

 beach, but never actually on salt-water. Like A. cancli- 

 dissima, they are often seen in flocks where plentiful. 



I 72. Ardea CANDiDissiMA (Gm.). 



Ardea candidissima, Sclater, P. Z. S. 1891, p. 135. 



(Sacaya.) 



This Egret is numerous on rivers or swamps in Central 

 Chili, where it is known as the "Garzetta" ; I did not see 

 any in Arauco, though a few may come there in summer, 

 and further south I did not hear of it. I got one at Sacaya, 

 as well as a specimen of A. egretta. I was told that they 

 had never come there previously ; at all events they appeared 

 to be chance migrants. 



73. N^CTICORAX OBSCURUS, Bp. 



Nycticorax obscurus, Sclater, P. Z, S. 1891, p. 136. 



(Sacaya.) 



The Night-Heron is common all through Central and 

 Southern Chili, the most general local name being '' Huara," 

 and in some places called '' Huarabo." 



I have forwarded an egg, which I was informed belonged 

 to this species ; I got it from a man who was a thorough 

 naturalist and not likely to make mistakes. The birds are 

 usually met alone, and, as a rule, by a river or stream. 

 They sit during the daytime in some thick bush or tree by
