Urdaibai Bird Center

Urdaibai Bird Center is a nature museum in Gautegiz Arteaga, set right in the heart of the Urdaibai Biosphere Reserve in the Basque Country. Opened to the public in 2012, the center combines two roles: it carries out scientific research on birds and their migratory journeys, and it presents that work to visitors in an engaging, accessible way.

What should you know before visiting?

The center is run by the Aranzadi Society of Sciences, an organization with more than 60 years of experience researching both natural and human sciences. As part of its work, Aranzadi also operates a bird-banding office that has carried out pioneering ornithological studies across the Iberian Peninsula. That scientific track record is what shapes the center's exhibits and educational program.

What will you see at Urdaibai Bird Center?

The main draw is an observation point that lets visitors watch birds and follow their seasonal migratory routes without disturbing their natural behavior. Because the center sits inside the Urdaibai Biosphere Reserve — the Oka River estuary, recognized by UNESCO as one of Western Europe's key stopover points on bird migration routes — the species you can spot vary widely depending on the season, from waterfowl and wading birds to raptors and woodland species.

Inside, exhibits explain the biology of migration, the research methods ornithologists use (including bird banding), and the ecological importance of the Urdaibai estuary as a habitat. This makes the center more than a standard museum — it functions as an active hub for wildlife monitoring paired with public education.

When should you visit?

Opening hours change with the season:

• February 28 to June 30: Tuesday–Friday 10:00–16:00, weekends and holidays 10:00–18:00 (closed Mondays)
• July–August: daily 10:00–18:00
• September–October: Tuesday–Friday 10:00–16:00, weekends and holidays 10:00–18:00
• November–February: weekends and holidays 11:00–17:00
• Closed on December 24, 25 and 31, and January 1 and 6

The best time to spot the widest variety of species is during spring and autumn migration, when the Urdaibai estuary becomes a stopover for thousands of birds traveling between Europe and Africa. Summer and off-season weekends offer the longest opening hours, giving visitors more flexibility when planning a trip.

How do you get there?

Urdaibai Bird Center is located in Gautegiz Arteaga, a small municipality in the province of Biscay (Vizcaya), in the Basque Country. It sits within the Urdaibai Biosphere Reserve, close to Gernika-Lumo and the Bay of Biscay coastline, making it easy to combine with other regional highlights such as the beaches near Mundaka or the historic sites of Gernika.

Frequently asked questions

Is Urdaibai Bird Center a museum or a bird-watching spot? Both — it operates as a nature museum with educational exhibits, while also offering a genuine observation point over the estuary where visitors can watch birds in their natural habitat.

Who runs the center? It is managed by the Aranzadi Society of Sciences, an organization with over 60 years of research experience in natural and human sciences, including ornithology and bird banding.

When is the best season for bird-watching here? Spring and autumn migration periods bring the greatest variety of species, since the Urdaibai estuary is a key stopover on Western Europe's bird migration routes.

Is the center open all year round? Yes, though hours vary by season — it's open daily in July and August, while in winter months it opens only on weekends and public holidays. It is closed on a handful of specific holiday dates around the turn of the year.
