Very many of these birds once lived on Ko-dima, off the coast of Fukuyama, 
Hokkaido, but have been exterminated by the foxes, as fox-farming is now 
carried on there. 
These investigations were carried out in July, 1927. 
The birds on Oh-sima Island live on the south-western slope of the hill, 
which is covered with weeds and shrubs. The southern projection is situated 
on the upper part of a precipitous cape, Namba-Misaki. The surface is loose. 
The burrows vary in length according to the nature of the soil; the holes 
being deep in soft earth and shallow where the soil is hard. 
The entrance to the holes is built beside the stumps of plants, the roots of 
shrubs, or near a rock, but on Oh-sima they are chiefly in the crevice of a rock 
or beside one.
