  • Meconema thalassinum (2)
    Meconema thalassinum (2) Another possible male of Meconema thalassinum drumming was found after filtering a recording including the strong songs of a field cricket Gryllus bimaculatus and a cone-head cricket Ruspolia nitidula. Now it seems to be more high pitched, but that must perhaps be dependent on the substrate. The three first "echemes" last 437, 404 and 534 ms, containing 27, 24 and 33 "leg-hits"; that is a rate of 59-61 hits/s. I have hard filtered the other species to allow to hear the insect drumming.

  • Meconema thalassinum (1)
    Meconema thalassinum (1) The bursts last 0.8, 1.1, 1.2 and 0.8 s. In the first two "echemes" that were analyzed, there was a pulse rate of 77.2 and 76.3, which is the double that what is commonly said (30-40/s at temperatures up to 25ºC, Ragge and Reynolds, 1998). I have not serously filtered the recording, as it's easy to hear, although there are another artists (in order of appearence: Gryllus campestris, Alytes obstetricans, Mecome athalassinum and Uromenus rugosicollis). At 14.6" there is another unidentified sound, but could be a twig break.

  • Unknown stridulation
    Unknown stridulation On three different occasions on july 2007 I could record this day-light sound, that could be either produced by a cricket, a cicada or another insect. The recordings were made with the microphone of a digital camera, which only registers below 8kHz, and the quality is rather bat. The frequency spectra seems to be high, mainly over 6 kHz. They are now joined in one excerpt with tree parts, but recorded the three occasions in the same place, in an abandoned field with some scattered trees. That's why I think it must be the same species, which I have not heard again. It seems the sound came from the canopy of a tree, but is not sure.

  • Chaotic picks?
    Chaotic picks? This recording was made with the help of the microphone of a digital camera, which only registers below 8kHz. On the other hand I had a Bat Detector device, tuned at 20kHz, switched on at 1.6", so the "output sound" of the Bad Detector device could be recorded. There are two kinds of sounds; the first reminds the sound of dozens of workers with picks in a mine; the second is similar to the sound of scratching a match in a match-box.

  • Strange owl?
    Strange owl? Recorded with the microphone of the digital camera by Ferran Bravo. The "song" was repeated every 12/15 seconds (now is "artificially" duplicated) Recorded one evening of January 2009 at 20:00 in a stone oak Quercus ilex forest in the base of a cliff. It could be an anomalous owl (Strix aluco, Otus scops, Bubo bubo)? Could it be a toad?

  • Cicada barbara lusitanica?
    Cicada barbara lusitanica? Recorded the 16th july 2012, 17:34 (unknown temperature, but hot, >20º, and windy) at a meadow with scattered Juniperus communis bushes. The recording has to be hardly filtered in order to take out the wind noise and other orthoptera species, such as Platycleis albopunctata.
