KUITTIWAKE. NATATORES. LARUS. 493 
with a greyish-white termination. Legs and toes grey- 
ish-white, tinged with flesh-red. Base of the bill livid, 
or flesh-red ; the tip blackish-brown. 
After the first auttmnal moult, a few grey feathers appear 
upon the mantle, and the greater wing-coverts acquire 
the same tint. The head and under parts become 
whiter, the crown, the back part of the neck, the breast, 
and flanks remaining streaked with pale clove-brown. 
After the second autumnal moult, the mantle acquires 
its permanent pearl-grey colour, and the quills their 
characteristic markings ; but some clove-brown spots re- 
main upon the wing-coverts, and the caudal bar is still 
distinguishable. These signs of immaturity disappear 
at the next vernal moult, after which the bird merely 
undergoes the mature changes incident to the seasons of 
the year.
