When the crops and gizzards of the young birds are opened in the cavern, they are found to contain all sorts of hard and dry fruits, which furnish, under the singular name of Guacharo seed (semilla del Guacharo), a very celebrated remedy against intermittent fevers.

The old birds carry these seeds to their young.

They are carefully collected and sent to the sick at Cariaco, and other places of the low regions, where fevers are prevalent.
