> So if I swapped the birdwatching with watching horses run or pigs fornicate with everything else being the same (hiking, breathing in fresh air, the eyes seeing natural sunlight etc), I would enjoy the exact same benefits the article claims birdwatching results in?
Those activities typically don't require observation and inference. A big part of birdwatching is identifying small, fast-moving animals that exhibit specific combinations of behaviors at specific times of the year based on specific climatic conditions. That sort of rapidfire pattern matching from video and audio info is probably a big contributor to what keeps the brain sharp.
We just started doing meaningful bird photography (as opposed to true birdwatching) last year and I agree with you.
The couple of times we've gone with guides who are serious birdwatchers, it is impressive to watch their abilities in this area of multimodal species identification (and male/female/adult/juvenile) in challenging visual and audio environments (and recall of species names in Latin, English, and Spanish).
Meanwhile I'm out there with my camera like "Hey, look at that beautiful red+blue bird!" ¯\_(ツ)_/¯
Probably a social aspect as well

So VR birdwatching works, or no?
Remember, if VR birdwatching works, then you can now watch small, fast-moving animals that exhibit specific combinations of behaviors at any time of the year from the comfort of your couch and thus, the benefits of birdwatching can be enjoyed by a much larger population.
