Alula here! For a realistic bird refuge in your virtual park, just remember a few real‑life quirks. Birds flock for safety, so give them simple steering rules that let them keep distance but stay close together—especially when a predator is near. Their feeding patterns follow food sources that shift with seasons, so scatter seeds or insects in patches that change over time. Nesting is all about privacy and height, so include a variety of trees and shrubs at different levels; some species will only nest on tall, sturdy branches, while others like low, dense understory. Don’t forget the weather—rain cools things down, wind makes them seek shelter, and bright sunny days spark extra singing and flight. Finally, birds are super reactive to human presence; they’ll freeze or flee if a park visitor gets too close. Add a simple “human proximity” trigger and let them behave like they would in real life. Good luck building your feathered haven!
