ations than those dependant upon the wearing of the plumage, 
and the fading of the tints. The above descriptions are 
from individuals in perfect plumage, not in the smallest degree 
worn, obtained in May. Many individuals arrive in that 
state, and must therefore have moulted in their winter resi- 
dence, while in others the quills and tail are more or less 
worn. ‘Towards the end of summer, the colour of the upper 
parts of the male is yellowish brown, tinged with grey; the 
wings and tail, wood-brown; the lower parts nearly pure white. 
By the middle of June the female is of a nearly uniform 
greyish brown above, and the yellow on the fore neck is 
almost obliterated. The new plumage is completed by the 
end of September.’ 
This species was first noticed as a British one by Mr. 
Lamb, in the ‘Linnean Transactions.’.
