NOTES: Daytime calling "pee-you". Nagra IV. ME-88. [These 30 vocalizations all represent the fully peaked form of the Initially Peaked Vocalization (IPV; following Smith, W. J. 1970. Displays and message assortment in Sayornis species. Behaviour 37: 85-112). Note that, the BNA account appears to have confused this vocalization with a type 1 Regularly Repeated Vocalization (RR1). Quality unchanged (2 - quite a bit of hiss) - 5 April 2005].
