Sand Martin Day Celebrated in Đelekovec

Sand martin population in Croatia drops from 30,000 pairs to fewer than 4,000 over the past 30 years

Đelekovec, 9 June 2025 – Over the weekend, the Sand Martin Day was celebrated on the banks of the Drava River near Đelekovec as part of the Municipality Day festivities. The colony of this endangered bird species at the Lubenovec site, downstream from Legrad, is one of the largest along the Drava River. In recognition of this, the village of Đelekovec was named Croatia’s first “Sand Martin Village” in 2024. This title highlights the importance of preserving natural habitats and showcases the successful collaboration between the local community, farmers, and environmental experts.

Sand martins – key indicators of healthy river ecosystems

Sand martins (Riparia riparia), Europe’s smallest swallows, nest exclusively in steep sandy riverbanks. Their presence is an important indicator of the health of river ecosystems. Unfortunately, their population in Croatia has declined from around 30,000 to fewer than 4,000 pairs over the last three decades.

The main causes of this decline include the loss of natural habitats due to river regulation, excessive pesticide use, draining of wetlands (which reduces insect populations), and human disturbance during the nesting season.

Education and community engagement are key to protection

Visitors had the opportunity to attend a presentation by a representative of the DRAVA LIFE project, participate in a creative workshop, and join a boat ride organized by the Rafting Club Koprivnica — all offering a closer look at the life of sand martins. The event emphasized the importance of responsible behavior near nesting colonies — such as avoiding noise, keeping a safe distance, and following guide instructions during the nesting period (late April to mid-July).

A key example of good practice is the collaboration between the Municipality of Đelekovec, the Puhar family farm, WWF Austria, and Croatian Waters. Through lease agreement adjustments, natural erosion of the Lubenovec riverbank is enabled, creating new suitable nesting habitats each year. This initiative stands as a model for successful cooperation between the local community, agriculture, and nature conservation professionals.

Special recognition goes to the school cooperative “Mak” from Đelekovec, whose project “Sand Martins in the Embrace of the Drava” qualified for the National Student Cooperative Fair. Students created educational and creative products to raise awareness about the importance of preserving this species.

DRAVA LIFE – Integrated River Management

The DRAVA LIFE project focuses on improving river ecosystems in Croatia, particularly in areas that are part of the Natura 2000 ecological network. By restoring the river’s natural dynamics and fostering cooperation among institutions, NGOs, and the local community, the project contributes to the protection of endangered species and habitats — while also helping to safeguard populated areas from flooding.

Presentation of the book and the video about Drava

As part of the celebration of the Day of the Municipality of Đelekovec, a presentation was held for the book and video by Goran Šafarek, created within the DRAVA LIFE project.

After Đelekovec was declared the First Sand Martin Village earlier in the day, the presentation of the book “Drava Yesterday, Today, Tomorrow” was held in the afternoon at the Đelekovec Fire Station. For the first time, the video “DRAVA LIFE – New Life for the Drava,” which showcases the activities of the long-term unique project to revitalize the Drava River, was screened.

Thank you to all the residents of Đelekovec and the surrounding area who attended. Special thanks for the interesting discussion and emotional impressions of what the Drava means to you and life by the river, with all its beauties as well as the threats that come with living by the river.

Avoid disturbance: Sand martin colony nearby

Libanovec – In order to contribute to the protection of the colony of sand martins at Libanovac and increase the safety of all visitors, who walk along the steep bank, the DRAVA LIFE team has set up a warning sign.

The sign is placed next to the information board about sand martin, where all nature enthusiasts can find more information about the importance of the sand martins, their colony and the DRAVA LIFE project. Štefica Sirutka, mayor of Đelekovec, an important partner in the conservation of this colony and the protection of the Drava River, attended the installation of the warning sign.
