It is found mainly on sandy islands along rivers and nearby fields. They also occur on coastal dunes and dry mud-flats.

Call of Sand Lark
The song of Sand Lark is varied and consists of rattling and tinkling notes high in the air followed by a series of dry rattling and whistled notes while descending lower.
Flight of Sand Lark
The flight of Sand Lark includes soaring followed by rapid wing flapping and pauses before parachuting down in a series of steps with glides while the wing and tail are held spread out. In the last stage of the descent it dives vertically before perching on a clod. They may also sing while perched on the ground, often with a slightly raised crest. Calls of other birds are also incorporated into the song.

The nest of Sand Lark is a deep cup placed on the ground in a patch of vegetation on the sand. The usual clutch consists of three greyish white eggs which are speckled in brown.
