Here are a few options for the description of the WordPress post tag “日間鳥類” in Traditional Chinese, catering to different needs:

**Option 1: Concise and Clear**

* **Description:** 涵蓋所有日間活動的鳥類，包括雀鳥、猛禽等。 (Encompasses all birds that are active during the day, including songbirds, birds of prey, etc.)

**Option 2: More Informative**

* **Description:** 標記指向主要在白天活動的鳥類。 範圍涵蓋了各種不同的鳥類，從常見的鳥類例如麻雀、山雀，到更具魅力的猛禽如鹰、隼等。 (Tags referring to birds that primarily are active during the daytime. This includes a wide variety of birds, from common birds like sparrows and tits, to more majestic birds of prey like hawks and falcons.)

**Option 3: Emphasizing Photography/Observation**

* **Description:** 專為日間鳥類攝影、觀察和物種識別而設的標籤。 包含您在白天可能遇到的各種鳥類。 (A tag specifically created for daytime bird photography, observation, and species identification. Includes the various birds you may encounter during the day.)

**Option 4: Simple and Direct**

* **Description:** 白天活動的鳥類。 (Birds that are active during the day.)

**Key Considerations When Choosing:**

* **Target Audience:** Who is reading your blog? Are they bird enthusiasts, photographers, or a general audience? This will influence the level of detail you want to provide.
* **Content of Your Posts:** What kind of posts will be tagged with “日間鳥類”? (photos, identification guides, general information, etc.)
* **SEO:** You can subtly incorporate keywords (like “鳥類” – birds, “雀鳥” – songbirds, “猛禽” – birds of prey) to help with Search Engine Optimization.

I recommend using Option 2 or 3 if you want a better description. Pick the one that best reflects your blog’s focus and what your readers will be looking for. Remember to add the chosen description in the WordPress tag settings.
