Everything I've read states that dragons are solitary creatures. They do not long for other dragon company, if you will. Additionally, it's not a good idea to house two dragons together (not sure if you were planning that, but thought I'd mention it). As for being bored, well, dragons while not fond of other dragon company, do love OUR company, usually. Our dragon is quite happy to be held and snuggled several times a day. I do notice that he seems a little "down" when we have a busy day and haven't had our usual "out of viv" time. Ours, in particular, loves to be held near a sunny window, and also LOVES to fall asleep on us whilst "burritoed" in his sock. Falling asleep on humans is prime beardie bonding and happiness time. When ours gets his usual lovin', he's more aware, alert and active. That said, dragons are desert lizards and do love the lounging that goes along with that. Could it be that he's just happily basking with that dragon-common lazy expression on his face? Or, did you just get him? Dragons take some time to acclimate to new environments, so he could just be in a down period, getting used to new surroundings and people. Or by bored, are you saying that he's actually lethargic (i.e., sleeping a lot, heading to the cool side of the tank instead of basking, etc.). If this is the case, you may have a dragon with a health issue, either internal, or enclosure related.
If you could be more specific as to his behavior, I know someone here would be able to help discern the issue a little better for you. There are many here who are "all knowing" in the subject of beardies (I'm not one of them, but I'm learning), and their behavior. I imagine someone might have a suggestion or two (or three), but specifics are always helpful, and to be sure, you will probably be asked to give some details as to his enclosure and routine, heating, lighting, feeding, etc.
Best of luck with your "bored beardie." Hope he's up and going soon!
