clicking

Question
My male glider continuously clicks his tounge at his mate all night long.. It doesnt matter if hes near her or on the other side of the cage, running around, ect.. Its just a constant clicking sound, any idea why?

Answer
This type of sound is a happy sound, it means contentment, your gliders will make lots of communicating sounds to one another,.. this particular sound means he is saying hello and is communicating to her and you perhaps that he is happy she is there and enjoys her company.. perhaps he it trying to woo her.. ;)
