Remarkable Birds

Untouched nature. Wetlands and coastal meadows. Falsterbo is truly a dreamlike stopover for millions of migratory birds – and a growing hotspot for ornithologists and birdwatchers from all over the world.

Morning breaks. A late but welcome autumn sun settles into its low path across the clear blue sky. Among the shrubs surrounding the Falsterbo Lighthouse, the nearly invisible mist nets are already in place, and the ringers enjoy a well‑deserved cup of coffee. It doesn’t take long before the winged visitors begin to arrive.

“Many birds migrate at night to avoid birds of prey. When dawn breaks, they spot the Øresund and dive down into the lighthouse garden to rest before the 21‑kilometre flight across the sound.”

This is explained by Sophie Ehnbom, the bird station’s head of ringing. A lifelong birdwatcher, she has followed migratory birds for as long as she can remember. Since the late 1980s, she and her colleagues have ringed hundreds of thousands of birds among the trees surrounding the lighthouse.

With its location at the very tip of south‑western Skåne, Falsterbo is a natural stop along one of Europe’s major flyways for millions of migratory birds each year. In spring and autumn, it is almost impossible to miss the tightly knit formations of calling birds overhead.
Among the vegetation of the peninsula, they pause on their intercontinental journey to recover, replenish their energy reserves and preen their feathers before the next stage.

It is easy to understand why the one‑hectare garden surrounding Falsterbo Lighthouse is such a powerful draw. Trees of various sizes have been allowed to grow freely among the wild grass, and along the narrow sandy paths there is an abundance of shrubs. It is also the only remaining grove on the peninsula. All around it, the golf course stretches out in every direction – undeniably scenic, but hardly an ideal resting place for goldcrests and robins. They need trees for shelter, and insects and berries for food.

“We do everything we can to preserve the garden’s natural vegetation. Millions of birds depend on it as a refuge. We have also conducted research and ringing here for over 70 years – and to continue doing so, we need the birds,” Sophie explains.

Bird ringing is, in fact, a relatively recent phenomenon. Only since the late 19th century have humans carefully captured birds and systematically attached small metal rings around their legs. Each ring bears a unique number that can be traced worldwide, from one ringer to another. It may sound surprisingly simple, but over the decades this method has provided answers to complex questions about birds’ lifespan, behaviour and migration patterns. During ringing, the bird is also weighed, measured, identified by species and checked for health. Everything is recorded together with the ring number.

“You never stop being amazed at how birds ringed here in Sweden turn up in different parts of the world – often accompanied by an unexpected story.”

One such story lies particularly close to Sophie’s heart. It takes us all the way to the cracked desert steppes of Iraq – right into a war zone. After an extraordinary artillery exchange, a soldier reportedly found a tiny ten‑gram bird, its ring still intact. Despite his own incredibly difficult circumstances, the man sent a letter to the Swedish Museum of Natural History in Stockholm to find out where the bird had come from.

It may seem completely absurd that a soldier in the midst of war would take the time for something so trivial. Yet it is also a beautiful and vivid illustration of the pure curiosity that the world of birds awakens in us.

It doesn’t always have to be that dramatic to spark fascination. The mere fact that a 13‑gram bird ringed in Falsterbo can cross the Øresund, travel down the continent and reach Italy in just seven days is enough to leave one in awe of their incredible determination.

But behind all the moving anecdotes, a more serious truth begins to emerge. The bird‑ringing work also offers a unique insight into the climate changes shaping our time.

“These days, the warmth lingers much longer into autumn, and as a result the birds stay up here in the north for longer as well. Even though it’s the final day of the ringing season, we’re still finding hundreds of birds in the nets. That’s unusual.”

With an undertone of concern, Sophie explains how a warmer climate affects the lives of birds. In itself, a longer stay in the north is not a problem. Birds adapt quickly. The real danger arises when nature’s other ancient rhythms fail to keep pace. What happens if the weather suddenly turns cold in the middle of the breeding season? Or if millions of chicks hatch early, before summer’s swarms of insects have had time to appear?

Unanswered questions like these hang over the morning’s otherwise peaceful ringing work, like a dense mist along the horizon.

“Of course it’s something you think about. But in the end, our job is to count and ring the birds, so that others can work out a way forward.”

Sophie and her colleagues gently remove the last birds from the nets and begin the final round of ringing for the season. No new nets will be set until spring arrives, when the birds return from warmer latitudes.

The bird station now becomes a place for research, but also an educational centre for young bird enthusiasts – an important task at a time when Sweden’s corps of bird ringers is in decline.

“Young people’s interest in nature has been weak for a long time. There is so much else to do. But I still have a feeling that the curiosity I’ve always had is on its way back. I’m hopeful,” Sophie concludes, with a certain light in her eyes.

The future is, as always, uncertain. But one thing is clear: in an increasingly unpredictable climate, the future of many bird species rests in the hands of the next generation of ringers. Passing on knowledge and passion therefore becomes crucial – and in this, Falsterbo Bird Station and the dedicated people working there play a vital role.
