**How to choose the best description:**

* **Consider your target audience:** Who are you writing for? Experienced bird owners, beginners, or a mix?
* **Reflect the content of the posts under this tag:** Does the post generally cover beginner topics, advanced techniques, or a range of topics? Tailor the description accordingly.
* **Keep it concise and easy to understand:** Even if you have a lot of information, make the description clear and quickly convey the main idea.
* **SEO consideration:** While primarily for user understanding, you might loosely incorporate a keyword or two (e.g., “八哥鳥飼養技巧” – Myna bird care techniques) to help search engines.

I recommend trying to incorporate the keywords that you expect would be searched for. Good luck!
