NOTES: Breeding status: ?territorial BNA: Primary Song "pit-tsee-eur" (RRV1) and "pit-eet" (RRV2); Initially Peaked Vocalization "phee-eur". mf

[This is the Primary Song of the species (sensu BNA) combining the fully peaked form of the Initially Peaked Vocalization (IPV) with type 1 and type 2 Regularly Repeated Vocalizations (RR1s, RR2s). See Figure 1c of Smith (1970a. Song-like displays in Sayornis species. Behaviour 37:64-84) for RRVs and Figure 1 of Smith (1970b. Displays and message assortment in Sayornis species. Behaviour 37: 85-112) for IPVs. Note that the BNA account appears to have confused the IPVs with RR1s and the RR1s with RR2s. Typical of the species (fide BNA following Smith), these 125 vocalizations are strongly biased towards IPVs, with only 25 RRVs given in all. Of the latter, the 15 RR1s are given at 0:18, 0:25, 0:35..., and the 10 RR2s are given at 0:14, 0:27, 0:38... Quality changed from 1-2 to 2 (relatively busy with other birds) - 5 April 2005]
