crocdoc, how did you train them to sit in that corner when they want to come out and sit in your hand like that?
It started with the male many years ago. I started letting him out of the enclosure for a wander around my place and he very quickly started to like that. They're really curious animals, so having a whole new world to explore is a big bonus. He started off being a bit nervous as he explored, but soon got more comfortable with it and it became part of his routine. Being let out was his reward, so training him to do things became easy. The enclosure door is pretty high off the floor so I'd put my hand out for him to crawl on and if he did I'd put him on the floor. If he tried squeezing past my hand, I'd keep moving my hand around so that it was in front of him and he quickly got the idea. On the hand or no going on the floor. Over time I realised that the most comfortable way (for both of us) to lift him out was if he put his arm between my thumb and forefinger so I could use it as a handle. By that stage we were doing it that way most of the time, anyway, so I decided to refine it and would always position my hand in a way that it became natural for him to use his left arm. Before long he started anticipating it by waving that arm and now he often does that before I open the enclosure door. The female had no interest in being let out until she was around four years old, because she hated people, but once she discovered the world outside the enclosure it became her thing to be let out as well and I started teaching her the arm technique.
The easiest place for me to lift them out is on the female's nest box on the right hand side of the enclosure, because it is elevated, so one day I decided that would be the only place from which I'd lift them out. That was an easy thing to teach. If I'm in the room and they're on the wrong side of the enclosure, I ignore them. If they scratch at the glass, I ignore them. The instant they head over to the nest box and sit there quietly tongue flicking, I walk straight over and let them out. Simple operant conditioning: ignore the behaviours you don't want, reward the ones you do. Took them no time to figure that one out. Now and then they slip up and scratch at the glass at the wrong end of the enclosure, but within a minute they'll usually stop, look over at the nest box and head over. They're pretty clued in reptiles.
in the second vid how did you call that monitor (computer doesn't have sound) and train him to come when called without him exspecting food?
I called him by clapping and calling his name. He is expecting food there, but not immediately. I used to feed the female in the enclosure while the male was elsewhere and preoccupied, but he usually figured out what was going on and would then be on the alert. Consequently it wouldn't take much to get him running over. I started off by clapping and then putting him in the enclosure, going to get food and then feeding him. The reward had to be delayed, for if I fed him immediately after clapping eventually he'd probably just run over and bite the clapping hands. This way he'd run over and then look at the enclosure, knowing he knew he had to be in there to be fed. In the video you can see him trying to get into the enclosure near the start of the video because I've called him over and he knew he had to be in there to get fed. Eventually I started calling his name as I clapped and then slowly reduced the clapping so he came by name only. I don't do that any more because even with the delayed reward it started to get a bit hairy at times having him run over with food on his mind.
