Calls. The contact note, when the birds are together, is pip or chip, and there are variations of tone from both sexes. The alarm call is a loud tchek! When nervous or apprehensive, such as when I am seen watching them through the window, the sentry bird (Restall 1995b) will utter a rapid tik tik tik tik, accompanied by tail jerking from side to side and very quick wing-flicking. The male, when calling its mate, utters a pee, peet or cheet, the female's reply is a pip or chip. Song and display. In undirected advertisement song (Fig. 1) the male stands at about 45 degrees to the perch, head horizontal, and sings at first a quiet tik tik tik tik tik tik tik which changes to more of a tuk tuk tuk tuk. This becomes a few long weeee whistles, each tending to descend, changes to a long drawn out weeeeeooooooooo legato (or long connecting note) first rising then descending, and ends with several ivee wee wee wee notes. The whole may last from 8 to 15 seconds and may be repeated many times. The legato is sometimes loud and penetrating and may be the only part of the song heard even a short distance away. When displaying to the female the male is slightly more hunched, with the bill pointing slightly downwards. The nape, bib and upper throat feathers are erected, but the chest feathers are depressed. The rump is ruffled. The flanks and belly feathers are fully erected, clearly displaying the white spots on the black.
