( Originally Published Early 1900's ) Very closely related is
the Least Petrel (Halocyptena micro-soma), found along the
Pacific coast from Lower California to Panama, the sole
representative of its genus. It is only about five and three
quarters inches long, and differs from the last mainly in
possessing a rounded tail and in the absence of the white rump.
It is a rare bird, and but little is known of its habits beyond
the fact that it nests on San Benito, a small rocky island some
fifty miles off the coast of the peninsula, placing its pearly
white egg on the bare rock, in the crevices of rocky ledges, or
among the loose stones.
