I think one of the drawbacks of VR birdwatching is that you are served the bird in focus, in frame, almost immediately - there's no search, there's no WTF is making that noise?

Some parts of birdwatching could be Virtual - watching a feeder somewhere (anywhere) waiting for birds to come in and watch what they do - or watching different trees/plants at different points in the year attracting different birds exhibiting different behaviours (eg. I have a love of seeing Tui[NZ] when Taiwanese Cherry or Kowhai are in flower, they gather in the tree at different times of the day when the nectar is at its peak, there are fights for dominance between the birds, there's a racket as they all feast, then boom, as quickly as they arrive they're gone again, off to the next tree)
