I've been mulling over this for a few days now...

In particular, I'm referring to resources such as Bison, maybe some kind of Bird resource... migratory animals essentially.

Since they usually travel annually/seasonally, I don't think I'd actually want to make them pop up on one tile and then disappear to another one since that'd be largely unrealistic as well as extremely annoying.

But I was thinking maybe they could cover a swath of land and have an animation that causes them to move slowly from one tile they occupy to another in a loop.

But then it raises other questions... do you get +1 supply of Bison per tile they occupy? If not, can you build a camp on any tile they pass through and get access to them? And shouldn't things like roads and such have a sort of penning-in effect on them? I mean, where humans encroach, most such herding species get gradually pushed into a smaller and smaller space... but you need roads to get to the camp... so that doesn't work? Maybe no railroads? Building mills, pastures, farms and towns should definitely have that effect at least...

Thoughts?

That's going to be tought to implement. No matter how you do it, there is going to something unrealistic or annoying about it. Letting them occasionally disappear and pop up somewhere else may be best way to do it.

While it's a nice idea, firstly it would be hard to implement, and secondly, if done wrong, it seems like something that could get quite irratating quite quickly.

Yes it's somewhat annoying, but it's simple. And you could find a balance so that it happens often enough to affect the game, but not so much that you are constantly chasing them down. Maybe even limit the jump tp a few tiles, or a continuous region of allowable terrain. (ie, buffalo would stay on the same swath of plains/grassland)
