AeroBird
Tired of the boring and empty sky in Minecraft? This mod will radically change your perception of the airspace, filling it with beautiful decorative birds!
The modification offers a unique mob spawning system based on biome tags. This means you can finely tune the appearance of various creatures depending on the terrain type through configuration files. For example, you can make spiders appear more frequently in sandy biomes, while birds inhabit exclusively mountain regions.

IMPORTANT: The mod requires the installation of the GeckoLib library.
