Situation of burrows. Quite a wide range of burrowing sites has been 
chosen. While a few were found half a mile inland under the roots of trees, 
the majority were in the cliffs and sloping seaward faces. In one place the 
flat cliff top two hundred feet above the sea, consisting of sandy soil held together 
by a matted rush-like growth, was undermined with burrows opening from the 
top and running underground in all directions. Most of them were separate 
and averaged 3 feet 6 inches in length, but in some cases one tunnel was found 
to branch off inside into two nests. Elsewhere there was a number of short 
“ runs ” 'with two entrances. 
Nest. Placed, not at the extreme end of the burrow, but a short distance 
from it, leaving beyond a chamber large enough to enable the bird to turn 
round. A larger quantity of nesting-material than is usual with most Shear¬ 
waters Avas used. Most of the nests contained two or three handfuls of twigs, 
broken root fibre and dead leaves. 
Eggs. Each nest contained a single white egg, more or less stained by 
contact Avitli the bird s feet. Those examined, varied someA\Iiat in shape and 
size, but the majority Avere ovoid, tapering rather finely at the narrow end. The 
surface is smooth, sometimes A\ r ith a barely perceptible gloss, and is minutely 
and sparsely pitted. All these characters, however, appear to be Available, 
both in presence and in intensity. Measurements: 61.5 to 68 mm. by41.5 to 
43.6 (64.5 by 42.9 aA r erage).
