Sorry can't really merge this for a bunch of reasons, I hope you understand:

• I'm not sure about the license of the 3D model
• The bird is quite weird (like, big?)
• The flock implementation looks very ad-hoc and does not really work
• The idea is for the birds/wildlife to not be distracting, they should be fun little additions that are randomly found but not too prevalent.

My idea of the birds is as follows: "Flat" eagle-like silhouettes going around the map but never landing, smoothly moving and turning. Flocks+boids can be interesting but they'd need to be rare and follow more conventional algorithms.

I also don't think they deserve to be entities as they shouldn't be interactable. Just a Vec somewhere in a Wildlife resource should be enough.

I'm sorry I can't really use the code you wrote, I should've guided you more from the start.
