Henk Meeuwsen, researcher at Geo-information systems, Alterra

The minute he heard his first nightingale, he was sold. ‘Sounds man’ Henk Meeuwsen records the sounds of nature. Mainly birds but also anything from running water to buzzing bees. This is a job for an early bird: birdlife is most active before dawn, when the surroundings are relatively quiet as well. CDs full of sounds with titles such as Blackbirds and More, Birds Top 100, or The Heath. Nice source of ringtones too, See: www.natuurgeluiden.nl
