One evening (20:00 h) of January 2009, in a stone oak Quercus ilex forest in the base of a cliff, it was recorded this song with the microphone of the digital camera by Ferran Bravo. The song was repeated every 12/15 seconds (now is "artificially" duplicated). It consists of two syllabes (one ascendent, the second descendent) in a low frequency spectra, less than 1 kHz.
The landscape picture is from a similar place not far from it.

It could be an anomalous song of an owl (Strix aluco, Otus scops, Bubo bubo)? Could it be a toad?
