Solitary or in pairs. Male performs spectacular aerial songdisplay, characteristic for all Certhilauda species. Male first flies low over the ground, then rises nearly vertically several feet into the air and closes its wings before reaching the high point. After that it nose-dives and descends vertically, not opening the wings before coming close to the ground. Whistles while descending; same song is also uttered from prominent perches.
Monogamous. Breeds September through December; nest often domed, clutch size ranges from two to three eggs; both parents feed the young.
Not threatened. Common in its limited southwestern African range. Range may have increased due to agriculture.
