Animals of any type sound like a great idea to me. I think its simple small things like that that could bring the park to reality. Sure a duck may not fit the theme you are going for but that's just it, its just a theme. I cant think of a park I have gone to that hasn't had birds or squirrels roaming around. It's the same as getting enjoyment in seeing how effective the facade is, and the behind the scene sets and animatronics. When you take a look around your park it could add another tiny element to its atmosphere.
You can also make the option to turn natural spawns off for those who think they ruin the park or something.
Of course, none of this is a deal breaker if left out lol
