This work has one peculiarity: the integration of fifty-eight professional and amateur recordists in a collection of bird sounds equivalent to 27 audio CDs. One thousand voices are represented out of 1200 bird species that have been selected from Southern South America (the "Southern Cone"). This number is close to the total of bird species that are likely to be found in the region, considering that about 100 species are pelagic birds and/or rare and very difficult to record and/or observe (except at their breeding colonies on remote islands of the Atlantic and Pacific Oceans). Countries and/or regions represented in this work are: Argentina (AR), Chile(CH), Paraguay (PY), Uruguay (UY), Rio Grande do Sul (Brazil: BR), the Antarctic Peninsula and the South Atlantic Islands.
56 Photographers, both professionals and amateurs added more than 3.000 photos of 850 species. The material presented is mainly intended for use in the field with basic equipment like
iPODs, iPhones, cell phones and mp3s.
Each file (whether audio or photographic) is presented with information in the following sequence: Generic name, species name, serial number, site name, location within the closest political unit (district/town) or geographic reference (rivers, lakes, etc.). Province/department, country, date, additional data (if any: male, female, juvenile, etc.) and author.
The order of appearance of the recordings presented has been prepared in such a way that the songs are firstly given and then the calls (though more generally, the range of possibilities is very variable). The user can find the kind of voice wanted with the ease of clicking on each example. In general, each recording plays only one type of vocalization. For space reasons and for practical use as a dynamic tool between the user and this sound guide, it is generally not expected that within a single recording different types of vocalization appear, but only one type. This system enables the user to move to the next file when not satisfied, before the end of a recording. This is ideal for quick searches. In the case of photographs, their order of appearance is based on quality (unlike the recordings).
