## 根因

用不透气的布料（如塑料、厚毯子）盖住鸟笼会积聚二氧化碳、减少氧气并导致过热，引起呼吸窘迫或死亡，尤其是在小鹦鹉或金丝雀等小型鸟类中。

## 解决方案

1. ```
   Use a breathable fabric like cotton or linen, and only cover the top and sides, leaving the front partially open for ventilation. Ensure at least 2-3 cm gap at the bottom for air flow. Example: a lightweight cotton sheet draped loosely.
   ```
2. ```
   Instead of covering, use a partial cover over the top half of the cage to reduce light without blocking airflow. Monitor temperature inside the cage with a thermometer; ideal range is 18-24°C.
   ```

## 无效尝试

- **** — Using a thick blanket to block all light, but this prevents air circulation; birds need some airflow even at night. (70% 失败率)
- **** — Assuming a mesh cover is safe, but if the mesh is too fine, it can still restrict airflow and cause condensation. (50% 失败率)
- **** — Covering the entire cage including ventilation slots, which are essential for fresh air exchange. (85% 失败率)
