NOTES: Purpose of sound: Singing in defense of nesting territory; Behavior accompanying vocalization: perched; When not vocalizing, bird was feeding and calling around bridge. [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 vast majority of the 31 vocalizations here (one during announcement) represent IPVs, which is typical of the species, but the fact that RR2 were given far more often than RR1s was said to be unusual. RR2s are given at 0:135, 0:225, 0:295, 0:365, and 0:59, but the only RR1 was given at 0:26. Quality added (1-2) - 5 April 2005].
