Over the course of 366 days I observed 6852 bird species in 40 different countries. To put things in perspective; there are currently about 10700 officially recognized species which means that I observed almost two thirds of all the bird species in the world in just a single year. https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/17f54707-4aa8-4daa-9ee3-ed0b5914805a/Geen+Dodo-64.jpg Talks - Birding lecture You can book me for a talk about birding or my Biggest Year, but I also give motivational speeches about pushing yourself to extremes to follow your passion and chase your dreams. Birding is versatile and so are my talks. https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/0fde58a2-1557-4d3f-ae31-e3ee5982bcd6/Arjan+Ted+Talk.jpg Talks - Ted Talk One eighth of bird species are considered endangered. That’s over 1000 species of birds. Our bird species are dying off at an alarming rate. They try to tell us this but we fail to listen. It is our responsibility to stop that. Before 2016, James Clements was the world record holder of bird sightings. That man now is Arjan Dwarhuis. Arjan tells us about the first time he saw an Arctic Jaeger off the Scheveningen coast and how it sparked his love for bird watching. https://arjandwarshuis.com/excursions daily 0.75 2025-11-25 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1663273880386-NDRLV91ROKG79BAMWKSC/baardman_Oostvaardersplassen.jpg Excursions https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1663273916468-IHVB83PZFPAFCT953FQY/steltlopers-westhoek.jpg Excursions https://arjandwarshuis.com/iucn daily 0.75 2026-10-01 https://arjandwarshuis.com/vogelspotcast daily 0.75 2026-02-24 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/52985b20-3d65-4284-bbd9-bf0b361238e8/De+Vogelspotcast.jpeg https://arjandwarshuis.com/collaborations daily 0.75 2026-02-24 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/be1cce1c-452c-44f9-9b76-710292caa0e2/Vivara-banner.png https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1686799d-9fbc-45d9-9d52-a6ba8f917efc/Arjan-en-Gisbert-Vogelspotcast-Vivara.webp https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/c1d5d845-44ad-4351-a530-55dd9c2f64e6/Vivara+logo.png https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1790808608293-7RL0GJQ6LJETBB8QDU3C/Canon-logo-Arjan-Dwarshuis-Sponsor.png Collaborations https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1790808608293-VGRBVZBAFYM2G6IRA8FN/Dagjeindenatuur-logo-Arjan-Dwarshuis-Sponsor.png Collaborations https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1790808609421-63SXFXE3HFM5L43Q5YMW/kite-logo-Arjan-Dwarshuis-Sponsor.png Collaborations https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1790808609474-0NV5U2U947ISB5977YIU/Nocpix-logo-Arjan-Dwarshuis-Sponsor.png Collaborations https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1790808610534-HMG20QT2HK9WQDWSN0VG/ogelbescherming+Nederland-logo-Arjan-Dwarshuis-Sponsor.png Collaborations https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/1790808610940-Y6V7LG0QTH43EG7MUR7T/Vivara-logo-Arjan-Dwarshuis-Sponsor.png Collaborations https://arjandwarshuis.com/documentaries daily 0.75 2026-10-01 https://arjandwarshuis.com/documentaries/nederland-waterland-vogelland-winter monthly 0.5 2026-10-01 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/967ffc30-3ee1-4957-8847-b82e28fac7ee/Screenshot+2026-10-01+at+02.26.21.png Documentaries - Nederland, Waterland, Vogelland - Winter Nederland, Waterland, Vogelland - Winter https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/8aa56959-99c6-40ae-a179-f4939e641565/Binnenstebuiten-logo-Arjan-Dwarshuis.png https://arjandwarshuis.com/documentaries/nederland-waterland-vogelland-lente monthly 0.5 2026-10-01 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/71d9c02c-0515-43ff-bdf4-9921702c4a76/Screenshot+2026-10-01+at+02.19.31.png Documentaries - Nederland, Waterland, Vogelland - Lente https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/8aa56959-99c6-40ae-a179-f4939e641565/Binnenstebuiten-logo-Arjan-Dwarshuis.png https://arjandwarshuis.com/documentaries/nederland-waterland-vogelland-herfst monthly 0.5 2026-10-01 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/3692a77f-a656-4e2d-95d8-955d92d2675c/Screenshot+2026-10-01+at+02.32.50.png Documentaries - Nederland, Waterland, Vogelland - Herfst https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/8aa56959-99c6-40ae-a179-f4939e641565/Binnenstebuiten-logo-Arjan-Dwarshuis.png https://arjandwarshuis.com/documentaries/nederland-waterland-vogelland-zomer monthly 0.5 2026-10-01 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/3692a77f-a656-4e2d-95d8-955d92d2675c/Screenshot+2026-10-01+at+02.32.50.png Documentaries - Nederland, Waterland, Vogelland - Zomer https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/8aa56959-99c6-40ae-a179-f4939e641565/Binnenstebuiten-logo-Arjan-Dwarshuis.png https://arjandwarshuis.com/documentaries/arjans-big-year monthly 0.5 2026-10-01 https://images.squarespace-cdn.com/content/v1/62a328721db04f35608ecebe/8ee7a799-47e9-4d6b-a78c-26158c7c0e77/Netflix-Arjan%27s+Big+Year-Documentary.png Documentaries - Arjan's Big Year Documentary A birdwatcher visits mountains, deserts and tropical regions to spot as many species as possible in an attempt to set a new world record.
