For the best chances of bonding, you’ll want a single budgie. Make sure when you approach him, you aren’t moving in fast and staring (or anything that might make you look most like a giant predator). Remember too, even after some time of gaining trust, not all budgies want to bond closely with a human.
IF you decide on another budgie, always remember to observe quarantine, and be prepared to keep them separate in case you get another who happens to be incompatible with your existing budgie. There is a risk of ending up with two separate budgies, with the scenario that neither one will want a close human bond. Hopefully that won’t be the case, but of course they’re all individuals, and is something to keep in mind.

, not for your existing bird. Remember the cost of vet care for an additional bird, and everything else that goes with it. Also, two budgies are much messier than one budgie! Keep us posted on whatever you decide.
