NATURAL HISTORY 
PENGUIN AUK. 
This bird is of a size far inferior to the 
penguin, but with nearly the same form, 
and exactly of the same appetites and man- 
ners. It. is beautifully variegated all over 
with many stripes, and diners from the 
penguin, in being much more slender and 
elegantly formed. It breeds on the island 
of St. Kilda, and differs chiefly from the 
penguin in size and colour. It is smaller 
than a duck ; and the whole of the breast 
and belly, as far as the middle of the throat, 
is white. It builds no nest, but lays its eg? 8 
either itt the crevices of rocks, or in ho es 
under ground, near the shore. It generally 
chooses the latter, as it cannot easily rise to 
the nest when in a lofty situation.
