A new study suggests that the mental workout involved in identifying birds may help protect the brain as it ages. Researchers used MRI scans to examine the brains of birdwatchers and found that expert birders showed greater structural complexity in several brain regions than novices, a difference that may help slow age-related cognitive decline.
The lead author was Erik Wing of the Baycrest Academy for Research and Education in Toronto, Canada. The research focused on neuroplasticity, the brain's ability to reorganize itself, and on brain organization, which is known to deteriorate with age and is tied to weaker cognition. Expert birders in the study displayed better brain organization than the novice birders who served as the control group.
The cognitive systems engaged during birding include attention, visual perception, and visual recognition. According to the findings, these faculties were more active during birdwatching, especially when a participant could not immediately tell which bird they were looking at. The combination of time outdoors and the effort to identify a bird from limited clues appears to hold promise for supporting mental sharpness.
A separate study of 388 birdwatchers in Poland found that passion matters alongside expertise. Participants who rated the hobby as important in their lives reported a higher level of psychological restoration after a birdwatching session than expert birders who were less enthusiastic about the activity. The results imply that someone who both values birdwatching and develops expertise may gain more than someone who does only one of the two.
Wing discussed the findings with the BBC's Becca Warner. According to Good News Network's coverage of that interview, Wing said, "I think there's a lot of benefit to incorporating more novelty in our lives, in midlife and as we continue to age." Wing also indicated to Warner that curiosity may be the most important factor behind the possible cognitive gains, because curiosity is associated with novelty, and new objects and ideas force the brain to reorganize, helping it stay flexible in later life.
For local readers, the takeaway is that it is never too late to start birdwatching. The research suggests that pairing genuine interest in the hobby with growing expertise may offer the greatest benefit, and that the simple act of paying close attention to the birds in local parks and backyards could be a practical way to support brain health with age.
