For this reason, this activity is increasingly being used in programs that aim to help people with dementia.
Studies show that people who have been birdwatching for years have differences in how their brains work. A study led by Erik Wing, at Baycrest Academy in Toronto, compared the brains of experienced birdwatchers with those of people who had no prior knowledge of birds using magnetic resonance imaging. The results showed that in experienced birdwatchers, areas of the brain associated with attention, visual perception, and object identification were more organized.
According to the researchers, these changes may be related to neuroplasticity, the brain's ability to adapt and form new connections. This raises the possibility that engaging in activities that require attention and concentration may help maintain cognitive function as we age. However, further studies are needed to fully understand this connection.
The benefits are not just related to bird knowledge or level of expertise. A Polish study of 388 observers showed that personal interest and enjoyment from the activity were also of particular importance. The more meaning and enthusiasm participants experienced, the greater the reported benefits for psychological well-being.
In Germany, bird watching has also been included in programs for people living in nursing homes. The installation of bird feeders in 65 institutions was associated with improvements in concentration, memory, mobility and well-being. Residents began to pay more attention to the activity around them, recognize birds and communicate more with family members. Following the positive results, several health insurance companies invested in the creation of special bird watching areas in hundreds of nursing homes in Bavaria.
Similar programs have been developed in the United States, where bird feeders and toys that mimic bird sounds are used to promote interaction and memory in people with dementia. Meanwhile, at the University of Montana, birdwatching is being incorporated into activities for people recovering from strokes and having difficulty speaking.
Researchers explain that this activity combines several important elements for the brain: attention, curiosity, emotions, movement and communication with others. Moreover, it does not require special equipment or trips to nature, as it can be practiced even from the window of the house.
Birdwatching can thus be a simple way to boost mental activity and strengthen the connection with nature, bringing benefits to memory and well-being at any age.
