CommentThis is an adult male 'Sky-pointing'. According to HANZAB, this display is used by a male holding territory to attract a female. The displaying bird stretches its neck upwards with bill pointed vertically, tail raised to some extent and wings closed. A wheezy disyllabic whistle is uttered during the display. The presence of the female, whether in flight or on the ground, is enough to elicit Sky-pointing. The display functions to attract the female to the site, to bring her back to it, or to discourage her from leaving. It may also help strengthen the pair-bond.
