As winter slowly fades and the first signs of spring appear, March becomes one of the most rewarding months to explore Croatia’s natural landscapes. Wetlands fill with returning migratory birds, forests awaken with new sounds, and meadows begin to bloom. For travelers seeking a deeper, more meaningful connection with nature, birdwatching offers a unique way to experience the country—quietly, responsibly, and with purpose.
At the heart of this movement stands BIOM, Croatia’s leading organization dedicated to bird and nature conservation.
BIOM: Protecting Nature for Over Two Decades
For more than 20 years, BIOM has been working to preserve Croatia’s biodiversity through scientific research, habitat restoration, public education, and volunteer engagement. Many of its initiatives are supported by European Union funds and focus on restoring ecosystems that are essential for rare and endangered species.One of the most significant examples is the Dinara back to LIFE project, through which more than 700 hectares of mountain grasslands were restored, alongside traditional wells, ponds, hiking trails, and dry-stone walls—creating sustainable habitats for wildlife.
Thanks to its long-term commitment, BIOM represents Croatia within BirdLife International, the world’s largest bird conservation organization.
Public engagement is central to BIOM’s mission. Each year, the organization hosts free guided birdwatching walks led by professional ornithologists, most often in Zagreb’s green areas but increasingly in other cities as well. These walks introduce participants to urban and wild biodiversity while promoting responsible nature tourism.
BIOM is also active throughout the country—from monitoring bird migration on Učka, protecting seabirds near Lastovo and Palagruža, and supporting griffon vulture conservation on Cres, to combating illegal hunting in the Neretva Delta and advocating for the ban of lead ammunition.

Croatia’s largest lake is a crucial stopover for migratory birds. Observation towers provide panoramic views of marshlands, making it a popular destination for both beginners and experienced birders.
Neretva Delta
The meeting point of river and sea creates a rich mosaic of lagoons, reed beds, and channels. As a key stopover along major migration routes, it provides habitat for thousands of migratory, wintering, and breeding bird species.
Risnjak National Park

Known for its forests and mountain wildlife, Risnjak also offers opportunities for observing woodland bird species. Some guided wildlife and birdwatching programs are listed on the park’s website, depending on season and availability.
Učka Nature Park

Overlooking the Adriatic Sea, Učka is an important migration corridor for birds of prey. It also hosts BIOM’s annual bird-ringing camp, allowing visitors to learn about migration research firsthand.
Volunteering and Guided Experiences
Almost all major nature parks and BIOM itself offer opportunities for volunteering, citizen science, and educational programs. Many parks also organize guided birdwatching and wildlife tours, especially in spring and autumn.To participate, visitors should contact the relevant park or organization directly by email or phone using the contact details on official websites. Advance inquiries are recommended, as group sizes and seasonal schedules are limited.
By joining these programs, travelers gain expert insight while actively supporting conservation efforts.
Responsible Birdwatching
Birdwatching is most rewarding when practiced responsibly. Visitors are encouraged to keep a respectful distance, avoid disturbing nesting sites, stay on marked trails, and follow local guidelines.Supporting conservation organizations, choosing guided tours, and respecting natural habitats helps ensure that Croatia’s wildlife remains protected for generations to come.
Did You Know?
Croatia even has its own birdwatching event. The Croatia Birdwatching Festival brings together nature lovers, photographers, and experts from across Europe. In 2026, the festival will take place in Zadar County from 24 to 26 April, exploring a unique mix of islands, lagoons, lakes, and mountains—highlighting Croatia’s growing role as a destination for sustainable nature tourism.Whether you choose a quiet morning in a wetland hide, a guided walk through forest trails, or a volunteer weekend in a protected area, spring in Croatia offers countless ways to travel with purpose. Follow the wings, listen to the calls, and discover a side of the country where nature truly leads the way.
