The first time I heard this sound, I thought the wheel squeaked. Then I thought it was Delta getting his claw caught while he was in the wheel. Then I heard it while he was in his sleeping pouch. It's like a squawk. Well, something you could confuse as a squeaking wheel. I hear it a couple times I think in this vid. Super cute BTW, but at the very end - 3:54 (it's 4:00 long) is a pretty clear instance of it. What's that sound?

Not my video. I have one glider. I just was trying to explain the sound & couldn't. It isn't in the sounds section here & heard it in that video that I found on YouTube & used it for reference.

That video

It's a good sample of excited gliders. As Karen mentioned, it's nothing to be alarmed about. Thanks for sharing, I enjoyed watching and listening to the glider's delight.

Phew, thanks! People keep describing the SM sound as a loud single crab. It really freaked me out when he did it with no apparent stimulus. I sat there going,

People also say you'll definitely know when you hear it.

But he is a lone glider.

But I do spend a lot of time with him.

But his toys are kinda lame.

But he still plays.

But sometimes he just grooms for a while.

But it doesn't seem excessive.

But WHAT'S THAT SOUND?

So, thanks!!! The tension is bad sometimes that he may be lonely. Been keeping my ear to the ground for a buddy for him at a reasonable price. Job hunting too, but that's old news. My current job refuses to pay overtime, but works me so much I don't have time for a second job. Hopefully soon I'll have the money to add an Echo to Delta. or perhaps a Foxtrot.

In the meantime I'll try to keep calm & remember the happy healthy single gliders out there.

My mental health may suffer before his does

It does, thank you. I feel better. And Delta's mood has seemed consistently pleasant. I have a possible addition to the family lined up to ease my worries of a single glider. He may have a buddy in a month or two.
