The spotted flycatcher, a bird that does come to Africa anymore.
For decades, millions of tiny birds have flown thousands of kilometers every autumn from Europe to Africa to escape the cold. But new research shows that one of these long-distance travellers, the spotted flycatcher, is no longer making this journey. The reason? Climate change. Europe is warming.
A paper published in Scientific Reports by scientists at the University of Málaga shows that this once strictly migratory bird is changing its habits. Using more than two decades of bird observations from the citizen science platform eBird, the researchers found that the spotted flycatcher is now regularly spending winters in southern Europe instead of Africa.
“Our results provide the first evidence of a regular wintering pattern of the species in the Western Palaearctic over the last decade,” the authors write.
The team analyzed 42 winter records of the bird between 2000 and 2024. Over 80 percent of these sightings were in Spain and the Balearic Islands, with a few others in Portugal, Turkey, and North Africa.
Until 2014, the bird had almost never been recorded in Europe during winter. But after that year–when European winters began turning warmer–flycatchers started appearing every season.
“The number of records per wintering season has increased in recent years,” the study notes, linking the pattern to “positive temperature anomalies in Europe between 2014 and 2023.”
In simple terms, Europe’s winters have become warm enough for birds that once fled the cold by flying thousands of kilometers south. Now, they can survive closer to home.
Why They’re Staying
The researchers found that temperature is the key factor shaping this new migration behavior. Milder winters mean more insects survive, providing food for the flycatchers, which are insect-eating birds.
“Temperature has the greatest influence on the winter distribution of the spotted flycatcher,” the scientists explain. “Warmer winters directly benefit the species by providing a more consistent food supply.”
This shift could even give the birds an advantage. Staying closer to their breeding grounds saves energy and lowers the risk of death during the dangerous flight across the Sahara Desert.
“If these favourable conditions persist, the wintering population size could continue to increase,” the study predicts.
A Sign of Things to Come
The scientists believe the spotted flycatcher may be an early example of a bigger trend among migratory birds.
“This species may serve as a model for other trans-Saharan migrants now wintering in the Western Palaearctic,” they write.
“If temperatures continue to increase, more individuals are expected to shift their wintering strategy from trans-Saharan to pre-Saharan migrants.”
In other words, as the planet warms, more birds that once flew to Africa might stop in Europe instead. This quiet change in bird behaviour tells a bigger story: climate change is redrawing the natural map of migration, one mild winter at a time.
VISUAL OF THE WEEK
We have rankings of all sorts in Africa. Should we be ranking Africa’s most polluted cities? I interviewed Prof. Engineer Bainomugisha, the founder of AirQo, an air quality monitoring project helping African cities tackle the growing challenge of air pollution. Listen to his response and insights on various questions on air quality.
QUOTE OF THE WEEK
“We need every African person to have an individual digital health card that contains their information, and every community health worker to have a digital device that allows them to collect information,” said Dr. Ngashi Ngongo, Incident Manager at the Africa CDC, describing the continental body’s ambitious agenda for data transformation.
RESEARCH HIGHLIGHTS
Africa’s Vegetable Farmers Battle Climate Change with Little Support: A new review of 60 studies shows that Africa’s vegetable farmers are adapting to climate change, but efforts remain uneven and under-supported. Most research and action are concentrated in rural areas of West and East Africa, while urban farming, vital for city food security, is largely ignored. Farmers face drought, erratic rainfall, floods, and heat, and most rely on technological fixes like irrigation and improved crop varieties.
Yet institutional and government support is weak, and the private sector is almost absent. Only a third of studies evaluated whether these adaptations actually work. Researchers warn that Africa needs stronger policies, urban-focused research, and sustainable funding to make vegetable farming resilient and secure future food supplies.

Africa’s Surgeons Push for Modern Surgery Amid Training Gaps: A new study shows that while minimally invasive surgery (MIS)—a technique that reduces pain, blood loss, and recovery time—is transforming healthcare globally, its growth in Sub-Saharan Africa remains slow due to limited training opportunities. Researchers analyzed 18 studies and found that poor funding, lack of equipment, weak institutional support, and too few skilled trainers are major barriers.
Still, successful partnerships with international institutions have helped launch promising training programs. The study urges governments, medical schools, and global health partners to invest jointly in training and capacity building. Experts say that with better funding and collaboration, Africa’s surgeons can fully embrace MIS and improve surgical outcomes across the region. [Reference, JSR Surgical Research]
Why Do Cholera Patients Die After Arriving in Hospital: The study found that most deaths during Malawi’s 2022–2023 cholera outbreak happened because patients did not get enough fluids through drips soon after reaching the hospital. Those who missed proper rehydration within the first six hours were much more likely to die. Other factors like age, gender, or vaccination did not play a big role. The research highlights that timely and adequate fluid treatment is the key to preventing deaths from cholera, especially during floods or cyclones that overwhelm health facilities.
