[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. The 74 vocalizations here alternate between IPVs and RRVs, with 47 IPVs, nine RR1s, and 19 RR2s (though the latter do not appear quite typical of this type based on figure in Smith). Both the lack of domination by IPVs and the fact that the majority of RRVs represent RR2 rather than RR1 is said to be atypical of this species. Quality added (2-1) - 5 April 2005]
