[This is the Primary Song of BNA, combining Regularly Repeated Vocalizations (RRVs, both 1 and 2) and Initially Peaked Vocalizations (IPVs; see also Smith, W. J. 1970. Song-like displays of Sayornis species. Behaviour 37: 64-84). Most of this is RRV1 (45 examples), but with 23 RRV2s scattered almost throughout the recording (0:05, 0:075, 0:12, 0:165, 0:205, 0:225, 0:245, 0:265, 0:305, 0:335, 0:375, 0:395, 0:415, 0:44, 0:46, 0:51, 0:55, 0:57, 0:59, 1:02, 1:065, 1:11, and 1:15). The last five vocalizations are "chevron-peaked" IPVs (1:18-1:26). Quality unchanged (2) - CAM - 4 April 2005]
