the upper wing-coverts, and more black on the outer webs of the 

 primaries. More or loss of a brown hood is assumed when the bird 

 is barely a year old, and the band on the tail is lost by the following 

 autumn, when the new primaries appear, with — as has been said — a 

 larger proportion of black than in the adult. In fact the duration 

 of the immature phase is very short. The bird does not breed until 

 the following (or second) spring. 



Occasionally the black from the margins of the inner webs 

 of the three outer quills runs in and reaches the shafts, much en- 

 croaching upon the usual white centres, though not to the same 

 extent on both wings of the same bird. This is noticeable in two 

 examples obtained at Dinapur in December. 



Hah. The Faeroes, Southern Norway and Sweden, Russia from 

 Archangel southwards, and the rest of Europe to the Mediterranean ; 

 eastward, across the temperate portions of Asia to Kamtschatka 

 (breeding). In winter, Gambia {fide Kendall), Nubia, the Red Sea, 

 the Persian Gulf, India, the Philippines, China and Japan.
