Our sugar glider is making weird noises, can you tell us what they mean?

Is it kind of like a quick bark that ends in a hiss? Sort of like a whistling sound? (I can't watch the vid, I'm on dial up!) If so, that is just your glider calling out to other gliders. Do you watch vids with gliders making noises? If your glider heard other gliders on the computer, she may be trying to contact them! I would suggest you get her a friend, they do get lonely!
