A new study reveals that birdwatching is not only a recreational activity but also a cognitive exercise capable of strengthening the brain and delaying aging.
Identifying species, distinguishing calls, and recognizing visual patterns simultaneously activate processes of attention, memory, visual perception, and quick decision-making, very similar to those involved in learning a language or playing a musical instrument.
Neuroplasticity in action
The brain does not remain static when a demanding skill is practiced consistently. Circuits are reorganized, useful connections are reinforced, and redundancies are eliminated, a process known as neuroplasticity.
- Musicians show changes in auditory areas.
- Athletes in motor regions.
- Birdwatchers in areas linked to visual identification and working memory.
The University of York study
Researcher Erik Wing and his team analyzed 48 birdwatching enthusiasts, divided between experts and beginners, aged 22 to 79 years.
- During brain resonance tests, participants had to identify birds in less than 10 seconds among very similar options.
- Experts correctly identified 83% of local species and 61% of non-local species, compared to 44% for beginners.
- Experts showed greater activity in the bilateral prefrontal cortex, intraparietal sulcus, and right occipitotemporal cortex, key regions for selective attention and fine visual processing.
Cognitive reserve and aging
Experienced birdwatchers showed a greater structural complexity in these brain areas, suggesting a more robust cognitive reserve. With age, this complexity usually decreases, but in experts, the decline was less.
According to Robert Zatorre (McGill University), this indicates that maintaining specialized skills can reduce the influence of aging on the brain.
Beyond the individual brain
Birdwatching also has social and environmental effects:
- Ecological awareness: birdwatchers detect concerning changes in habitats and migratory cycles earlier.
- Citizen science: many biodiversity monitoring programs rely on volunteer observers.
- Conservation: direct connection with nature fosters social support to protect natural spaces and address the climate crisis.
Birdwatching is an activity that combines pleasure, learning, and brain health. Although longitudinal studies are still needed to confirm its direct impact on neuroplasticity, the data suggest that practicing birdwatching can be a powerful tool to keep the brain active and young while strengthening the relationship with the natural environment.
