Air temperature °C. (Duellman 1978b, Köhler & Jungfer 1995). The species can be expected to occur also in the Yungas de La Paz region. Natural history: All specimens were found at night perching on leaves of bushes or ferns at m height at the edge of humid montane primary forest. Calling activity was highest at dusk during light rain. Juveniles were found from December to February. Vocalization: Advertisement calls were recorded on 18 December 1998 at 1250 m , Provincia Chapare, Departamento Cochabamba. Calls always con- sisted of two pulsed notes repeated in a rapid succession; call duration varied from 194-214 ms (mean ± ); note duration varied from 49-68 ms (mean ± ), with the second note being slightly longer; within notes pulses were repeat- ed in regular intervals at a rate of 155-194 pulses per second (mean ± ); call energy was distributed between 1400 and 2800 Hz; an upward frequency modulation was recognizable within the calls, with the first note having a domi- nant frequency peak at approximately 1700 Hz and the second note having the peak at approximately 2200 Hz; the second note showed a higher amplitude; calls were emitted in irregular intervals. Three calls of two individuals analyzed; air temperature was °C during Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bonn, Zoologisches Forschungsinstitut und Museum Alexander Koenig
