During the breeding season, when the male and female are together, the male utters a hoarse roar or bellowing, which, it is said, can be heard at the distance of more than a hundred yards.

The female never uses her voice, and the male only at these times; so that when the people hear this noise, they know that the two are together.

They were at this time (October) laying their eggs.

The female, where the soil is sandy, deposits them together, and covers them up with sand; but where the ground is rocky she drops them indiscriminately in any hole: Mr.Bynoe found seven placed in a fissure.

The egg is white and spherical; one which I measured was seven inches and three-eighths in circumference, and therefore larger than a hen's egg.
