This latest publication presents sound recordings of 564 bird species.
An astonishing 2317 separate sound recordings are represented. Included are the sounds of nearly all the birds predominantly inhabiting the life zones of Ecuador's eastern lowlands. The habitats of these lowlands include forests of various types (such as varzea and terra firme), clearings, black and white water lakes and rivers, and islands. The goal was to achive the highest degree of completeness, not only including song repertoires but also a wide variety of calls and mechanical sounds for each species.
The package consists of 1) a CD containing all vocalizations in MP3 format, announced in English, with each track containing a single file of all vocalizations for each species, and 2) a data DVD containing a separate MP3 file for each vocalization without announcements.
