Bi7-ds of Central Patagonia. 399 



evening large flocks ascend the river Chupat for many miles, 

 flying in from tlie sea, and fish in the river during the night. 



Phalacrocorax, sp. ?t. 



A few frequent the rocks at the mouth of the Chupat ; but 

 they never ascend the river like Phalacrocorax brasilianus. 

 On the 30th December I found about sixty pairs nesting on 

 Tombo Point. They had chosen the most inaccessible ledges 

 of the rocks ; and each nest contained one egg or a young 

 bird, the former of a dirty Avhite colour. I secured a young 

 bird in down after some difficulty. It has the head, neck, 

 and the whole of the upper parts, the lower part of the 

 stomach, and thighs sooty black, breast and upper part of 

 the stomach mottled with white, iris dark brown, naked 

 skin round the eye red, legs and feet and beak very dark 

 lead-colour. 



Ardea cocoi. 



Not uncommon in the Chupat valley and along the Sengel 

 and Sengelen. 



Ardea egretta. 



Occurs occasionally at Chupat. I was credibly informed 

 by one of the colonists that this bird once nested in a reed- 

 bed in the Chupat valley ; and my informant discovered the 

 nest whilst cutting the reeds. I saw one specimen on the 

 Sengel. 



Ins light orange ; beak dark orange ; legs, feet, and claws 

 black, soles of feet primrose. 



■^Nycticorax obscurus. 



Resident, but not numerous. Seen once on the Sengel. 



CiCONIA MAGUARI. 



Seen in October in the Chupat valley, and in November 

 at the mouth of the Sengel. 



i [Mr. Dumford considers this Cormorant to be P. carunculatus (Gm.) ; 

 but as lie has not sent a specimen, it is questionable whether it is really 

 this species, so great is the confusion prevailing respecting the Cormorants 

 of this group. — Edd,]
