The beautiful white flowers of the plant are never found growing on the north side of the stem.
With the Indians, the pithaya enters, of course, into religion, and the beautiful macaw (guacamaya), which revels in the fruit, is associated with it in their beliefs.

The bird arrives from its migration to southern latitudes when the pithaya is in bloom, and the Indians think that it comes to see whether there will be much fruit; then it flies off again to the coast, to return in June, when the fruit is ripe.

The following gives the trend of one of the guacamaya songs: "The pithaya is ripe, let us go and get it.

Cut off the reeds! [4] The guacamaya comes from the Tierra Caliente to eat the first fruits.

From far away, from the hot country, I come when the men are cutting the reeds, and I eat the first fruits.
