No — birds are biotic, not abiotic.

- Abiotic factors are the non‑living physical and chemical parts of an environment (temperature, sunlight, precipitation, soil, water, pH, nutrients, fire, etc.).
- Biotic factors are the living components (plants, animals, fungi, microbes) and their interactions — birds fall into this category.

Nuance: birds (and other animals) can change abiotic conditions — for example, seabird guano increases soil nitrogen, burrowing birds alter soil aeration, and large flocks can affect vegetation cover and microclimate. Those effects don’t make birds abiotic; they’re biotic agents that can modify abiotic factors.
