A study led by Erik Wing found differences in brain activity and organisation between expert birdwatchers and novices, including in areas involved in attention and visual recognition. The findings do not prove that birdwatching slows cognitive decline, and researchers say more work is needed; separate research suggests birdwatching may support wellbeing among older people.
Research described by the BBC links birdwatching expertise with differences in brain activity and organisation, while separate studies suggest that watching birds may support wellbeing among older people. The findings do not establish that birdwatching prevents or slows cognitive decline, but they add to research on how sustained interests and nature-based activities may affect ageing and dementia care.
Neuroscientists led by Erik Wing at Baycrest Academy for Research and Education in Toronto compared MRI scans from expert birders and novices as participants identified birds. Experts showed different patterns in brain regions associated with attention, visual perception and recognition, with more activity in some areas, particularly when identifying unfamiliar birds.
The researchers also assessed how organised and coherent different brain regions were. Some areas in expert birdwatchers showed higher organisation than those of novices of the same age. The BBC report says organisation tends to decline with age and that lower measures are associated with reduced cognition. The comparison, however, cannot show whether birdwatching caused the differences or whether people with those brain patterns were more likely to become experts.
Other research in the report examined birdwatching in care settings. A study of 388 birdwatchers in Poland found that people who described birding as an important interest were more likely to report psychological restoration than highly skilled but less enthusiastic birders. In a separate project, researchers installed bird feeders at 65 nursing homes and reported improvements in residents’ wellbeing and cognition after several weeks. The report does not provide detailed effect sizes or establish that birdwatching alone caused those changes.
Birding as a Possible Brain Activity
The findings point to birdwatching as an activity that combines attention, visual discrimination and learning, functions that researchers can study as people age. If further research supports a link between sustained birding and preserved brain organisation, it could help clarify how mentally engaging hobbies relate to cognitive ageing. The current evidence is an association, not proof that taking up birdwatching will protect someone from decline.
The care-home work also has practical relevance. The BBC describes residents watching birds from shared indoor spaces, suggesting that access to nature need not depend on travel or specialist equipment. For some people with dementia, a calm shared activity may offer opportunities for connection and positive emotion. Such benefits should be understood as supportive experiences, not treatment or a replacement for clinical care.

From MRI Scans to Care Homes
The BBC report brings together different kinds of evidence rather than describing one trial that tested whether birdwatching slows dementia. Wing’s research compared expert and novice birders in a laboratory setting, focusing on brain scans during bird identification. It examined people with different levels of expertise; it was not reported as a study that followed participants over time to measure a change in cognitive decline.
Other studies considered reported restoration and outcomes in nursing homes. The account also describes a weekly group at Forge Mill Lake in England, run by the charity Age UK. A participant with dementia, identified by a pseudonym, initially seemed apprehensive but later smiled and laughed while watching birds with his daughter. Jenny Budinger, a community dementia adviser at Age UK, said the outing let him be present without worrying about his memory or confidence. That account illustrates an individual experience, not a clinical result.
“The findings may indicate that acquiring this skill earlier in life might produce benefits that continue through to older adults.”
— Erik Wing, research lead at Baycrest Academy for Research and Education
Cause and Cognitive Effects Remain Unclear
The brain-scan comparison cannot determine whether birdwatching produced the observed differences, whether those differences helped people become expert birders, or whether other factors contributed. The report also says more research is needed to understand how brain organisation relates to wider cognitive function. It does not establish that birdwatching slows the progression of dementia or prevents age-related decline.
The nursing-home findings are also limited in the account provided: the report does not give detailed numerical results, explain the assessment methods in depth, or establish how long any changes lasted. It is unclear whether improvements were caused specifically by birdwatching rather than by other changes, social contact or the setting. The available source describes promising associations and reported benefits, not a settled clinical recommendation.
Longer Studies Needed
Researchers will need studies that follow participants over time to test whether starting or continuing birdwatching is linked to changes in cognition, and whether any effect differs by age, expertise or health. Research in care homes would also benefit from clearly reported measures, comparison groups and follow-up beyond the first weeks.
For now, the report presents birdwatching as an accessible activity that some older adults and people with dementia enjoy, alongside early research into possible psychological and brain-related associations. The next milestone is stronger evidence separating the effects of the activity itself from those of social interaction, prior experience and other factors.
Key Questions
Does this research prove birdwatching slows cognitive decline?
No. The brain-scan study found differences between expert birders and novices, but it did not prove that birdwatching caused them or that it slows dementia or age-related decline.
What brain differences did researchers report?
Expert birders showed different activity in some brain regions involved in attention, visual perception and recognition. Some regions also had higher measures of organisation than those in novices of the same age.
Can someone benefit without being an expert birder?
The report describes studies suggesting that interest in birdwatching may be associated with psychological restoration and that residents in nursing homes reported improvements after bird feeders were installed. These findings do not establish a guaranteed benefit for every person.
Is birdwatching being used in dementia care?
The BBC reports that birdwatching groups operate in care settings in several countries and describes an Age UK group in England. The activity is presented as a supportive social and recreational option, not a replacement for dementia care or medical treatment.
