I would start bonding by putting your glider in a bonding pouch, DURING the day is best to start, at night he will want out to play. let him fall to sleep in pouch and you can also talk to him. Since he is biting, I would not stick my hands in the bonding pouch, after a few hours put him back in cage. After some bonding time,maybe days or even weeks, my wife would make a fist and put it in sleeping pouch with glider, so he would sleep with her scent, ALSO a fist makes it harder to bite you, some of the gliders would try, then just tire out and go to sleep. Keep your movements SLOW of your glider is scared/jumpy.
Put your scent on a small piece of fleece and put into his sleeping pouch in cage, rescent after a few days, so he sleeps with your scent during the day.
to start do not feel the need to put your hands all over the glider, he may not be happy with you yet. If you get in a playroom or tent, let them walk on you, explore, you do NOT have to touch him if he is going to bite. Feed him some treats then back away with your hand.
make sure your hands are not scented with soap or food that he could smell and think is food.
give your glider TIME, weeks and months.
I have gone slow with connor, its been many weeks, but he will now climb on my hand thinking he can get a treat, he was a rescue, not mistreated but ignored and scared of people, he has not bitten me. but he will crab and if I move fast lunge at my hand, then sniff then be ok.
