Vo c a 1 i z a t i o n : Advertisement calls were recorded on 2 January 1998 noith of Remates, Parque Nacional Amboro, Provincia Florida, Depaitamento Santa Cnaz, 2300 m Calls consisted of 4-8 notes, the first notes repeated in regular inter- vals of 14-16 ms, and the last one being separated by an interval of 59-61 ms. Call duration varied from 152-245 ms (mean ± ). Mean dominant frequen- cy was 3560 Hz. The calls were emitted in regular intervals with a repetition rate of approximately seven calls per minute. Sixteen calls of two individuals ana- lyzed; air temperature was °C during recording. The calls described by Marquez et al. (1996) from Rio Chua Kocha (recorded at approximately same temperature) differ somewhat with respect to a higher domi- nant frequency (4039 Hz), shorter intervals between notes (9 and 42 ms), and number of notes per call (6-7). These differences might correspond to individual variation, because individual call variation was also recognizable in recordings from north of Remates. Remarks: Cochranella flavidigitata Reynolds & Foster, 1992 is a junior syn- onym of C. bejaranoi (Harvey 1996)..
