During the months of November and December, this bird was 
found breeding in great numbers, and like most of the Ptfbcellariidce, 
they dig a long tunnel or burrow in the sand or soft earth, 
many of these burrows are several feet in length, and a single egg 
is deposited at the extremity, which when fresh is snow-white,
