Irides hazel; bill dark brown, paler at base of the lower 
mandible ; legs and toes pale brown. 
The November adults are shewing signs of wear, and the 
December young birds are much worn. 
The April birds have completed the moult and are in full 
new dress. 
The young bird taken in February is moulting into the 
adult dress. 
The commoner of the two Pipits found in the Ajo district, 
where it is exceedingly plentiful, spending most of its time 
on the ground, but occasionally sitting on the tops of the 
plants or on the wire fences. 
The nest is placed on the ground under a tuft of grass, 
often in the footprint of a horse or cow, and is composed of 
grass lined with hair. Four eggs form the full clutch, though 
three is the usual number.

The November and December birds are much worn, and 
the April examples have completed the moult and are in full 
new dress, shewing a deeper tinge of buff on the chest. 
Nearly as plentiful as A. correndera in the Ajo district, 
and can be always distinguished in life from that species by 
the lighter and more uniform colour of the back. 
A. furcatus resembles A. correndera in habits and manner 
of nesting. Three eggs appear to form the complete clutch.
