This is long and boring and I didn't know where to put it
But I thought I'd just share a little story about Bud learning how to climb out of the cage and meeting two larger parrots. I found it slightly amusing and thought I'd just post something other than questions about Sam.
A few nights ago, I was just sitting down on my bed with Sam. I always leave the door of the cage open in case the other wants to come out and so it's easier for me to put them in it. I was just playing a game and letting Sam watch because she likes watching my phone/computer. I hear little claws hitting the bars of the cage and think nothing of it because I figured Bud was just running around in the cage.
A few minutes later, Elvis makes this confused squawk and I looked over at him. I see this ice blue thing on the door of the cage and there's a budgie staring down at my cockatiels like "what on earth are those and why are they under my cage." (because we put them up there due to lack of other spaces). Bud looked up at me, noticed i was staring at him and he runs back into the cage and climbs up to a perch like nothing happened.
So apparently little bud figured out that he can come out of the cage through that large opening in the front, but there are larger parrots under him.
Unexpected second story from a few minutes ago:
I was sitting here typing this post and I hear Elvis chirping/screaming like there was something in the room (of course there is). I knew I left the cage door open while I came in here to close my tabs so I could go be with them a while. My first thought was that Bud had probably fallen out of the cage since he already came out. I went to my room, and once again there's this tiny bird sitting on the cage door staring at them. Elvis is at the back of the cage standing straight up and chirping loudly, while Priscilla's sitting there like "what's going on." I start to go put him back in the cage until I was done, and he runs back in again.
Long stories short: Bud's finally learning how to leave the cage on his own.
This is just a safety reminder in order to avoid unnecessary accidents.
When having the cage's door open to allow a pet bird to come out of the cage and go back in as they please, it's very important to keep close supervision of the pet bird(s). Even in a bird proofed and safe room, accidents can still happen and when having different species of pet birds sharing the same room it's even more vital to keep a watchful eye.
Until you have a better understanding of your cockatiels temperament, it would be best for you to discourage your budgies from landing or climbing on the cockatiel's cage because your tiels can bite the budgie's delicate feet and can even severely injure the toes in the process.
RIP sweet Tito (Summer 2008 - January 17th 2013).
You are missed and never will be forgotten.
