Abstract
The advertisement and encounter calls of Arthroleptis schubotzi NIEDEN, 1911 are described. Recordings were taken in situ at the Makerere University Biological Field Station, in Kibale Forest National Park, Uganda.The advertisement call is a high-pitched metallic sound, with either two or three notes per call, a dominant frequency around 4700 Hz and a mean call duration of 158 ms. The encounter call, previously unknown for this species, is a screeching sound, consisting of a series of pulsed notes (pulse train) ending with a single high pitched note. Minor variations exist in the number of pulsed notes. The dominant frequency of the pulse train is 4400 Hz, the high-pitched sound centers around 4600 Hz. The mean duration of the encounter call is 541 ms. The pulsed note lasts 334 ms and is the longest note in the entire call repertoire of A. schubotzi.
