why not link to that here instead video

Three good reasons:

1. It’s a video-sharing community for watching while you eat
2. The video features specific bird calls that are impossible to transcribe
3. I liked the video

If you don’t like the video, you’re free to post the article to its relevant community.

Then why not link to that here instead video?

Because this is a community literally about videos??

Are you asking why OP posted a video in the c/mealtimevideos community?

The verbal kind smartass. Birds don’t have a writing system (yet).
