KITTIWAKE. 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 autumnal 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.
