It’s been a while since the last update, but a lot has happened since then!


The project on Walcheren – a collaboration with local farmers – to test food plots for turtle doves has now finished. The project was a follow up from research in the UK, which showed that a lack of food (seed) in spring could be one of the main issues for turtle doves during the breeding season.


While we were not able to confirm this during our project in Zeeland, and we were ultimatly unable to find the 'perfect recipe' for turtle dove food plots, the results were still very valuable. We learned a lot about creating suitable food plots and how to manage them, and about how the tagged turtle doves use the landscape on a daily basis. Their use of supplementary feeding areas and of stored/spilled grain earlier in the season stood out once again, alongside their clear preference for areas where the 'small-scale landscape' of pre-agricultural intensification (areas with smaller fields, hedgerows, scrub, field margins, and semi-paved farm tracks).

So, the search for a (simple!) and reliable food-related conservation measure continues. But with the knowledge we’ve gained, we’re a step further along.


👉 Curious about the results? The full report is available on the Downloads page.


At the end of the project, we also created a practical guidance document on how to create and manage turtle dove food plots. It is still a work in progress, and will change as we continue to learn more, but it’s a great starting point for anyone who wants to try boosting food availability for turtle doves. You can find it on the Downloads page too.



With the support of the Province, two new projects have started in Zeeland


1. Tailored advice for landowners (Walcheren and Beveland) Whether you're a private landowner, a charity, or a business... if you’d like to do more for turtle doves and biodiversity in your area, feel free to get in touch. Together with Stichting Landschapsbeheer Zeeland, we are offering free, tailored advice and support. It doesn’t matter whether you manage a campsite, farm, sports park, business terrein or just have a large garden – we can look at the whole site and provide advice for both small and large-scale improvements you can make to your landscaping and/or management. While we specifically tailor changes to suit turtle doves, many other animals, insects and plants will benefit from them as well.


2. Monitoring the local turtle dove population on Walcheren and Noord-Beveland

Provincie Zeeland wants to know more about the turtle dove population on Walcheren - how many return from Africa each year to breed, and whether the population is growing. In recent years, a hunting ban in southern Europe has led to strong population growth in France and Spain. The question is when the Netherlands will also begin to see population growth. With the (unfortunate) reopening of turtle dove hunting this year in parts of southern Europe (albeit in lower numbers than before), this makes it even more important to keep a close eye on the breeding population.

To do this, a colour ringing project has been started, marking turtle doves with yellow colour rings, each with two large black letters. This makes it possible for birdwatchers, photographers, and members of the public to recognise individuals from a distance.


📩 If you spot a colour-ringed turtle dove, send me an email with the details, location and date. I’ll reply with more info about the dove – its name, where and when it was ringed, and other interesting facts.


🙌 Want to get more involved? We’re always looking for good spots to feed and ring turtle doves from April to June. If you have turtle doves in your garden or nearby, and you’d like to help, get in touch.



With the summer drawing to a close, turtle doves are busy fattening up and startig their journey back to Africa. So I’ll end this update by saying:


✨ Please leave your stubble fields standing until the end of the month – it gives the birds the fuel they need for their long migration south.

In 2021, our pilot year, the first 'foraging fields for turtle doves' were set up by participating landowners and farmers. A total of 6 small fields were created around our study areas near Westkapelle and Oostkapelle.


These fields were visited every week during the growing season, to see if they were suitable for hungry turtle doves. Farmers have been hard at work, hoeing, milling, and mowing the fields in an effort to create suitable feeding habitat for the doves. It's been a steep learning curve, and has resulted in a number of changes in our sowing and field management.


This year marks the second phase of the project: additional farmers have joined the project, the seed mix and sowing methods have been adapted, and we're testing different management strategies... but is all the effort worth it? Are the feeding fields of any use? What wildlife come to the fields?


With the help of camera traps and field observations, we've found the fields to be excellent habitats for insects and birds. This spring the fields abuzz with insects visiting the early blooming flowers, and atwitter with goldfinches and linnets coming to feed on early seeding mustard. Some birds, such as barn swallows, come for the insects, while other species, such as European quail and stock dove, come to feed on the seed.

In 2021, turtle doves were seen and heard around 4 of the 6 fields, though very few were observed on the fields themselves. This led to changes in field sowing and management, but also highlights the need for more detailed information on turtle dove movements.


This June, four European turtle doves have been caught and tagged with accurate, lightweight (4.6g) transmitters which will record their location at fixed intervals. Since being tagged (between 8th and 17th June), the doves have given us nearly 500 coordinates from areas they have visited, and they all seem to be doing well. All this information will be analysed to identify where the doves find their food; we want to know more about what they need at a foraging site, so we're better able to tailor the foraging fields to their specific needs.

Foraging Fields for Turtle Doves - Pilot Year


After a cold start to the year, rain that lasted for days and then a bit of a heat wave, it’s been incredibly difficult to make our sown fields suitable for foraging turtle doves. All 6 participating fields were sown in the first half of May, and we are only now seeing the first plants coming into seed.

Photo: We are testing 2 sowing periods during this project: spring and autumn. This May the first seed was sown into our spring fields.


Trap cameras have been deployed, and a small group of volunteers have been visiting the fields to monitor them for any sign of birds or animals using them. While this information is extremely valuable, it currently asks a lot of perseverance from them: without seed, the fields have of course been incredibly quiet. Hopefully this will quickly change once the first seed is available.


The trap cameras have picked up photos of crow, magpie, mallard duck, wood pigeon and stock dove, along with various other animals (hare, fox, and roe- and fallow deer).

Since May, we have also been kept busy with ongoing communication surrounding the projects.


On behalf of all partners, BirdLife NL released an online article on Nature Today on 14th April (‘Lichtpuntjes voor de zomertortel’), marking the official start of the Foraging Fields for Turtle Doves project.

The return of Jos the turtle dove led to his beautiful species gaining much media interest from the PZC, Omroep Zeeland and Vroege Vogels in May. NPO Radio 1 broadcast a short piece about turtle doves and our research in Zeeland on the 20th June on their Vroege Vogels program (similar to the BBC’s Springwatch). You can still listen to this online – it is approx. 81 minutes into the program. Photo: Corstiaan Beeke


Poldernatuur Zeeland gave two excursions in June regarding this new research: one for the deputy minister of Zeeland Anita Pijpelink, and René Steijn, the other for a group of agriculture and landscape specialists (SCAN). A further presentation and excursion is planned in July for their member council.


We are looking forward to a busy summer and, with a bit of luck, our spring-sown fields will follow suit and soon be buzzing with wildlife.
