Dr. Burmeister tells us that he has seen the Condor in the Sierras of Cordova and Aconquija, though it is more prevalent in the districts of the Western Cordillera.
In the territory of Chupat, Durnford met with it at Ninfas Point in November, and tells us that when the colonists are hunting in the neighbourhood of the sea-coast the Condor is the first of the bird-scavengers to make its appearance after game has been killed.
During his subsequent excursion to the Sengel river in the interior, the Condor was commonly observed throughout the journey wherever the rocks were high and steep. Several pairs were noticed nesting on Nov. 16th, but the nests could not be reached.
My own experience of the Condor is restricted in seeing one individual, flying above the sea-shore, south of the Rio Negro.
[Order VIII. STEGANOPODES.]
[ Fam. XXXIV. PHALACROCORACIDÆ, or CORMORANTS.]
The only family of the Steganopodes that can at present be inserted in the Argentine list is that of the Cormorants, though doubtless other forms of this Order (Sula, Phaethon, and Fregata) will be hereafter found to occur on the coast with more or less frequency.
