NOTES: Range status: NORMAL; Breeding status: UNKNOWN; General climate: CYCLIC WET-DRY; Age: UNKNOWN AGE; MALE(S) 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 Smith), these 62 vocalizations are strongly biased towards IPVs, but the larger of RR2s (0:315, 1:08, 1:38, and 1:48) relative to RR1s (1:10 and 1:44) may be unusual. Quality changed from 1-2 to 2, 2-1 (second part is better than the first) - 5 April 2005]
