Bluebird Minion Questions

So I think the bluebird is really cute but I would like a few answers before I go and get one. (This also applies to the opo-opo and nutkin if anyone knows)

1. Does it really respond to the /beckon emote? (I've seen cases where it doesn't respond, but they were very old posts)
2. If I sit down or fish, will it sit on my shoulder too after the emote?
3. Does it do anything else?
4. Can I run and have it continue to sit on my shoulder or will it fly off?

Thanks in advance :) If anyone had a video of the interactions and would like to post it, that would be even more amazing!

Edit: Thank you so much for answering!!! :)

For bluebird:

1. No, it only randomly decides to sit on you.
2. Yes, but only randomly like in 1.
3. Same minion interactions as all the others (walks (flies) up to another minion and stares at it). Other than that, no.
4. As far as I know, it will fly off if you move. I'm currently waiting for my bluebird to sit so I can test this.
Edit: Nope, it flies off if you move.

For opo-opo/nutkin:

1. Yes.
2. Yes.
3. Nutkin's idle animation is tumbling over the nut it carries.
4. They will continue to sit even if you move.
