If you are interested in Bioacoustics, I invite you to join the facebook group BIOACUSTICA-LATINOAMERICA (a forum of >900 members interested in Bioacoustics). This group provides a forum for nature recordists and bioacousticians throughout Latin America to discuss bioacoustics research, recording techniques and equipment, inform members of upcoming workshops and events, and provide a means by which members can share their sound recordings.

If you are interested in Nature Recording and live around Washington DC-Maryland  area, join the Maryland Nature Recordists Group!

SONAT, my private collection of audio recordings, started in 2002 and contains recordings of animal sounds (mainly birds) and soundscapes. My recordings are produced using monaural, stereo, mid-side, and multi-channel systems and collected for scientific purposes and made during my travels. The majority of the sounds are recorded in Mexico, but recordings from other countries are being archived as well (e.g. Cuba, Panama, Puerto Rico, USA, Germany, France, Belgium, among others countries).

If you want to hear more about my recordings, you can look for my latest audio guides in the BIRD SONGS OF MEXICO website. These CD’s are designed to help you learn specific calls and songs, therefore, giving you a better experience in the field. You might only travel to a certain birding spot once in your lifetime and guides such as these will help you ID rare species by ear quickly and accurately.
