The Condor feeds upon dead and putrefying carcases, 

 l)Ut two or more will sometimes unite to overpower the 

 llama and other large animals. They will even attack 

 a heifer ; they pursue it for a long time, wounding it with 

 their beak and talons until the poor animal sinks to the 

 ground l^reathless and overwhelmed with fatigue. 



The female Condor makes no nest, but lays her eggs 

 upon the bare rock, simply selecting a spot where there 

 are cavities large enough to prevent them from rolling- 

 down when she descends upon or rises from them. The 

 situations chosen for incubation are always nearly inac- 

 cessible. The eggs are white, and are said to be usually 

 two in numljer.
