Apart from seeing birds, my main passion is to capture their vocalizations, I have made sound recordings of over 4,600 species of bird, the majority of which (more than 18,700 recordings) have been uploaded to the outstanding xeno-canto.org website. Many can also be found at the Avian Vocalizations Center ( Michigan State University). I have also donated thousands of recordings to the British Library, many of which are on cassettes made prior to the digital age.

​

Thousands of people, including bird guides, birders, bird photographers and researchers, use my bird sounds for playback to find  birds, or for taxonomic research. 

​

I have made many unique recordings, and various birding DVDs and Apps, such as the SASOL eBirds of Southern Africa, and the Birds of Colombia DVD (by Peter Boesman), have licensed sounds from me for commercial use: if you are interested in doing the same, please don’t hesitate to contact me.
