Mr. Xantus found this Quail breeding in great abundance at Cape St. Lucas. In one instance he found four eggs on the bare sand, under a pile of driftwood, without any trace of a nest. In another, three eggs were found on the bare ground, under a fallen cactus. In a third case there were nine eggs, also laid on the bare ground, but in the shade of a jasmine-bush. They were frequently found sheltered under piles of driftwood.
The eggs of this Quail are subject to great variations in marking, and also differ somewhat in size. They are sharply pointed at one end and rounded at the other. One egg, measuring 1.30 in length by 1.00 in breadth, has a ground-color of a creamy white, freckled with markings of a uniform shading of an olivaceous-drab. Another, measuring 1.22 by .91 inches, has the ground-color of the same, but the markings are larger and more confluent, and their color is a rusty drab. A third is 1.18 by .95 inches; ground-color a creamy white marked by large scattered spots of a chestnut-brown.
