What is the Big Day

The National Park Dunes of Texel and the Bird Information Centre Texel, in collaboration with BirdLife Netherlands, are again organising a Big Day on Texel. The Texel Big Day forms the start of the Wadden Islands Bird Festival (12th and 13th May 2018) and of the Dutch National Bird Week (12th to 21th May 2018). Join the Texel Big Day and make your birdwatching count!


Texel Big Day: A charity bird race on 12th May 2018!

During the Texel Big Day, teams of up to 4 birdwatchers try to see or hear as many bird species as possible on Texel within 24 hours, and all on bike. Teams start on Friday night at midnight and finish 24 hours later. The Big Day is not only great fun, but also raises awareness of the amazing diversity of Texel’s bird life.


The Big Day also raises awareness and money for Texel’s birds. In 2018, we aim to raise awareness for the House Martin. The House Martin has also been chosen as the Dutch bird of the year by BirdLife Netherlands and Sovon. The Texel Big Day will aim to raise money to help the species on Texel.

We support all teams participating in the Texel Big Day with tips and inspiration for sponsorship, promotion and advice to see as many species as possible.

If you want to participate but do not have a team please let us know: This email address is being protected from spambots. You need JavaScript enabled to view it.. As we will be able to put you in contact with others in a similar position.

On your bike

The Texel Big Day is carried out on bike and loan e-bikes are available free to participants (limited availability). You could alternatively hire a normal bicycle or bring your own.


We encourage all teams to raise as much money as possible for the annual good cause. We aim for a minimum sponsorship of € 200 per team, but as in 2017 we are hoping for much more. We can help support teams in finding sponsors through providing helpful sponsorship tips from experts.

12th May 2018 will be the second Texel Big Day, and our goal is to make this a regular international event to raise awareness for birds and birdwatching. The organisers are open to tips and feedback to ensure that we make it the best Texel Big Day possible.

Follow the teams on Observation.org

Every team inputs their sightings throughout the 24 hours in world.observation.org. This is done via the apps: iObs (Apple) or ObsMapp (Android). That way everyone can follow each teams progress in the field. How many species have they seen? Who is in the lead? Which species are the teams still missing? This makes the Texel Big Day even more exciting. You can also help the teams on the day by seeing which species they still 'need'. Can you help a team with your sighting of a Fieldfare, Long-tailed Tit, Jay or Sparrowhawk?

Waarneming.nl is the Dutch name and sister site of Observado.org and the largest database of sightings in the Netherlands. It’s free to submit, free to use and available in many languages!

Click on the team name to see the species they saw, the route they took and the number of species per hour. Also a great way to prepare for the next Texel Big Day.

Texel Big Day 2018 supports: House Martin

The money collected by the Texel Big Day and the Wadden Islands Bird Festival will be used to help House Martins on Texel. Money will be collected through participating teams and sponsorships.

House Martins still breed on Texel, but just like so many other places in the Netherlands the species is declining. There are several reasons for the decline, such as the dry summer of 2017 where many nests fell because the clay dried out too much. However, there are also still people who remove the nests intentionally because they feel that the House Martins make too much mess. Information and education can make the difference, and we aim to inform people about these wonderful summer visitors. We also want to increase the number of appropriate nesting sites in suitable areas. We also want to encourage people to make small muddy areas in gardens and fields to ensure the House Martins can find enough nesting material. By participating in the Texel Big Day, you’ll be ensuring the future of House Martins on Texel.

What happens with the donations ?

With the collected money, the charity ‘Texel Bird Island’ (Stichting Texel Vogeleiland) will ensure that information about House Martins is circulated and practical measures are undertaken to improve the breeding situation for the species on Texel.
