Scared something's not right

[M.Bear]

Weird bird like call from Sebastian he's not acting right? He did this weird call a few times? What's wrong with him?

The sound babies make is a 'bird like' sound. What do you mean he's not acting right?

[Coralreefer]

Did you get a recording of it?

They can be very vocal and not have anything wrong with them.
Maybe spooked or maybe just trying to get yer attention.

Is he acting weird or just making new sounds?
