Birds of Central Patagonia. 399 
evening large flocks ascend the river Chupat for many miles^ 
flying in from the sea^ and fish in the river during the night. 
PhalacrocoraXj sp. ?t. 
A few frequent the rocks at the mouth of the Chupat; hut 
they never ascend the river like Phalacrocorax hrasilianus. 
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 white 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. 
— Y-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. 
Iris light orange j beak dark orange; legs, feet, and claws 
black, soles of feet primrose. 
*Nycticorax obscurus. 
Eesident, but not numerous. Seen once on the Sengel. , 
^ClCONIA MAGUARI. 
Seen in October in the Chupat valley, and in November 
at xhe mouth of the Sengel. 
i [Mr. Durnford considers this Cormorant to he P. carunculatus (Gm.); 
hut as he 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.]
