OIL-BIRD (Steatornis caripensis). Also called Guacharo . 
Length: 1% feet. Range: Northern South America. 
The oil-bird is so named because of the great 
masses of valuable fat which cover its body, especially 
when it is young. The flesh of this bird is relished by 
natives, and its oil is used in place of butter.
