Atmospheric Fauna: Unofficial Fabric Port
by Aarow
Atmospheric Fauna: Unofficial Fabric Port brings Fabric support to the Atmospheric Fauna crows, adding ambient wildlife to Minecraft Java Edition.
What it does
The mod introduces crows as new ambient wildlife that fits naturally alongside vanilla creatures. Birds make the environment feel more alive while keeping the original atmosphere of Minecraft intact.
This is an unofficial Fabric 1.20.1 port of Atmospheric Fauna, which was originally built for Forge. The port was produced by running the Forge build through the Connector mod, so Fabric players get the same content without a separate Forge install. It is licensed under the GNU General Public License v3.0 only and is open source, with the source code publicly available.
Installation needs Cloth Config API and Fabric API alongside the mod. Players add it to their own game, and a server needs no copy. Only the 1.20.1 version is covered, with the latest Fabric file dated 2026-06-11.
Key features

Vanilla-friendly design

Connector-based port

Use cases
Livelier landscapes

Who it’s for: Players on Fabric 1.20.1 who want more wildlife in their world. Because the mod is client-side only, it suits single-player and multiplayer players who want the birds without asking server owners to change anything.
How it compares
Ambient Birds is a Fabric mod with an MIT License, client-side only, but published for 1.21.2 – 1.21.10, so it does not cover 1.20.1. Overwhelmed is a Fabric mod for 1.20.4 that runs on both client and server and is open source under the MIT License. Both differ from this port in their version range and environment.
