The long-billed pipit or brown rock pipit (Anthus similis) is a passerine bird which has a wide distribution. A number of subspecies have been created for the populations in Africa, through the Arabian peninsula and South Asia. The systematics of this complex is yet to be clarified. Most birds are residents or short distance migrants.
This is a medium-large pipit, 16–17.5 cm long, but is an undistinguished looking species on the ground, mainly sandy grey above and whitish or pale buff below. It is very similar to the tawny pipit, but is slightly larger, has a longer tail and a longer dark bill.
The long-billed pipit's flight is strong and direct, and it gives a characteristic chupp call, similar to desert lark. Its song is like that of the tawny pipit, but slower and more varied, sri...churr...sri...churr…sri..churr. Like its relatives, long-billed pipit eats seeds and insects.
