In 2016 I set a world record. In one calendar year I observed 6852 bird species in 40 different countries.

To put things in perspective; there are currently about 10900 officially recognized species which means that I observed almost two thirds of all the bird species in the world in just a single year.

Why I did it..

  • Birdlife Preventing Extinctions Programme

    Of course a year like this would mean nothing without a good cause.

    I raised money for the groundbreaking Birdlife Preventing Extinctions Programme. This programme aims to prevent the extinction of all globally threatened bird species by applying an active, innovative and highly effective methodology.

    In total I raised almost 50 thousand euros, which was used entirely to save critically endangered birds from extinction. I thank all who have contributed to this succes.

  • Watch the award winning documentary Arjan’s Big Year, by director Michiel van den Bergh.

    Arjan’s Big Year premiered in October 2017 at the Wildlife Film Festival Rotterdam. The documentary was nominated for the Best Newcomer Award and won the Public’s Choice Award. Subsequently Arjan’s Big Year showed in 18 cinemas throughout the Netherlands and had its television premier December 14th, 2019 on NPO2.

    We are very proud to finally present you the English version! We would like to thank Peter Stoel (HeadQ Virtual & Post Production), Daan Lugtendorff, Mees van der Velde and Leon Bos (Nootweer Music) and Mark Collier for making this production possible.

    All profit will go directly to the BirdLife Preventing Extinctions Programme.
