Wildlife biologists aren't going to refer to simulated ducks to research their behavior in more depth.

I'm pretty sure behavior is simulated all the time in everything from migration to predator prey dynamics, to population dynamics, and so on. If we don't use simulations to understand all the little nuances and idiosyncrasies of behavior right now that's probably just because at present that's extremely difficult to model. But I suspect they absolutely would be used if such things were available. Of course, they would be treated as complementary to other forms of data, but wouldn't be disregarded outright.
