162 Mr. H. DurnforcPs Notes from the 
horses, cattle, sheep, or other carrion, and it is said some¬ 
times to pick out the eyes of very young sheep. On Sep¬ 
tember 18th an undoubtedly genuine egg was sent me from 
Entre Rios. A nest I found myself near Relgrano was in 
the middle of a large swamp; it was a massive structure, 
composed of sticks and lined with a little coarse hair and 
sheeps wool, and was full of putrid bits of horse-skin and 
bones of fish; it measured 5 feet round and 1^ deep, and 
contained three young ones about a week old. Two of these 
I preserved, leaving one in the nest; but it was gone on 
October 6th, and the nest relined with cowVhair, evidently 
for a second brood. On the 13th no eggs had been laid. 
Phalacrocoracidas. 
Phalacrocoraoc brasilianus I often see. I shot one, March 
25th, on Flores Island. 
Ardeidas. 
Ardea cocoi is tolerably common both in Banda Oriental 
and the banks of this river. On October 3rd I saw a Little 
Bittern, probably Ardetta involucris. I have also met with 
another species of Heron, which I take to be Ardea sibilatrix ; 
but I have not yet made it out satisfactorily. 
Ciconiida:. 
Ciconia maguari is common in every marsh of any extent. 
PLATALEIDiE. 
Falcinellus igneus is very common; it has a strong smell, 
owing to the carrion it eats. During the last fortnight in 
September I noticed a large flock flying northwards ; a 
friend who lives on the other side of Buenos Ayres noticed 
one also. There are still (Oct. 15th) some about here. 
Palamedeim. 
Chauna chavaria is common on all sides of Buenos Ayres. 
On October 3rd I observed a pair near here; but I have not 
yet ascertained if they breed in the neighbourhood. When 
wounded it is said to defend itself with its formidable spur.
