Birdwatching rewires brain, slows cognitive decline
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
MRI studies found expert birders had denser tissue in attention and visual brain regions than novices.
Bird identification may exercise memory and attention, a possible aid for older adults.
Background
Birdwatching is increasingly seen as a valuable activity for elderly people and dementia patients, with groups set up in nursing homes in the UK, Germany and the US. Erik Wing, a cognitive neuroscientist at Baycrest Academy for Research and Education in Toronto, Canada, led brain-imaging research comparing bird experts with novices. A separate team led by researcher Kals placed bird feeders outside 65 homes so residents could watch from indoor common areas. More than a third of American adults — some 100 million people — enjoy birdwatching, according to the Croton Chronicle column.
How it unfolded
- Oct 2025A study in Nature Communications found people with more creative experiences had more youthful-looking brains, cited as a building block for the birdwatching research.
- Mar 2026A Canadian study in the Journal of Neuroscience compared MRIs of expert birders to novices and saw greater tissue density in key brain regions among experts, young and old.
- Oct 19, 2026BBC Future published an article on birdwatching rewiring the brain and slowing cognitive decline.
- Oct 20, 2026Cary Andrews' Croton Chronicle column argued birdwatching is good for the brain.
- Oct 23, 2026A BBC article on the topic was dated in the feed.
Who’s saying what
- Expert
- Erik Wing said the diverse mental processes in bird identification — memory, pattern recognition, visual search and attention — may drive the observed brain changes.
- Caution
- Wing also said the findings don't prove whether structural brain differences are the cause or effect of birdwatching expertise.
- Support
- Researcher Kals said the findings were clearly positive, with participants becoming more cognitively agile and more able to follow conversations and recognise birds.
- Support
- Jenny Budinger, a community dementia advisor at Age UK, described a participant as present in the moment and not worried about his memory or confidence.
Still unverified
Erik Wing said the findings don't prove whether the structural brain differences are the cause or effect of birdwatching expertise.
