252 BRITISH BIRDS. 
legs, feet, and claws blackish brown; irides dark brown. The female 
resembles the male in the colour of her plumage. In autumn the general 
colour of the upper parts is a richer brown, and lacks the slate-grey 
on the head and nape, which are almost uniform with the back; the 
dark centres are somewhat more pronounced; the general colour of 
the underparts is white, tinged with buff, shading mto brown on the 
flanks, and marked on the sides of the neck and across the breast with 
large dull streaks of brown. Birds of the year resemble adults in this 
plumage, but are more streaked on the underparts. In autumn plumage 
the Alpine Pipit very closely resembles the Rock-Pipit, but may easily 
be distinguished by the colour of the outer tail-feathers; in the present 
species they are marked with white, whilst in the Rock-Pipit they are 
marked with smoke-brown.
