One of the most surprising examples of this effect is birdwatching, which researchers note is not just a hobby but a beneficial practice for mental development.
What Science Shows About Expertise and Memory
- The meta-analysis “Experts' memory superiority for domain-specific random [...]” confirms that experts in their field remember significantly more details than novices, even when the information is random. Source
- The study “Domain-Specific Knowledge and Memory Performance: A Comparison of High- and Low-Aptitude Children” shows that children with deep expertise (for example, in sports, chess, or another domain) have much better memory for topics related to their expertise, which can compensate for other weaker cognitive skills.

- The review “Benefits of nature exposure on cognitive functioning in …” demonstrates that spending time in nature, becoming familiar with flora and fauna, including birdwatching, is linked to improvements in working memory and concentration in children. Source
- Specifically on birdwatching: the National Geographic article “Can bird-watching improve your child’s memory?” describes how birdwatching enthusiasts develop expertise that helps them notice visual details, making it easier to learn new bird species and retain similar information. Source
Mechanisms: Why Expertise Helps Memory
Here are the key cognitive processes that explain how developing deep knowledge helps a child improve memory:
1. Expanded Knowledge Network
When a child becomes familiar with many details in a particular domain (for example, bird species, colors, behaviors, habitats), these details create “mental links.” New information is easier to integrate into existing networks, which simplifies memorization.
2. Enhanced Attention to Detail
Experts develop the ability to notice subtle differences — beak shape, feather patterns, characteristic sounds. This sharp attention to detail strengthens information encoding and reduces memory loss when recalling.
3. Use of Memory Strategies and Generalization Skills
Children with expertise often unconsciously use strategies (grouping, highlighting key features, comparing with known examples) to memorize new stimuli, building on already acquired skills. This accelerates learning and reduces cognitive load.
Practical Tips for Parents and Teachers
To make birdwatching or any other expertise truly beneficial for memory, you can:
- Encourage your child’s interests — whether it’s birds, dinosaurs, cars, animals, or even music.
- Stimulate active observation — reading guides, discussing details, keeping a journal of observations.
- Create opportunities for interaction with experts or participation in clubs and groups.
- Combine nature observation with visual and audio materials: pictures, sound recordings, photo documentation.
- Take a step-by-step approach: start with general traits (size, color) and gradually move on to finer distinctions.
Limitations and What Remains to Be Learned
Despite encouraging evidence, there are still unanswered questions:
- It is not always clear how much expertise effects transfer to entirely different types of tasks.
- The age ranges in which expertise provides the greatest benefit are not fully understood.
- Sometimes experimental conditions (for example, children already strong in a certain area) are difficult to replicate in a regular classroom environment.
