How do you tell if a budgie is happy?

Answer 1

It's not.

Would you be happy if you were confined to a single room of your house for your entire life?

The best rabbit habitat involves one in which either rabbits are given hours of supervised free roam time outside of the cage or are able to roam free in a bunny proofed area that is connected to their cage.

Yeah, but you're not a bunny and they have different personalities so this question is still unanswered. :)

I'm not a bunny but I speak rabbit (and English, I've fixed your mistakes above). And if the question being answered is dependent on the rabbit's personality we would need to know the personality wouldn't we? And since knowing the rabbit's personality is dependent on speaking rabbit I'm pretty sure I've answered this question. However, I'm sure some nitwit will come in and say how happy their rabbit is being confined all of it's poor life just so the person asking this question can feel good about the choice they've made to cage their active and intelligent pet rabbit.

~Hey, stop being all sarcastic with each other. Even if you could speak rabbit... did you talk to this persons specific bunny? I don't think you did. So, I believe the asker is looking for signs that the bunny is content. Personally, my bunny, Blaze, loves his cage. I have the door open pretty much anytime I'm home so he can run around and after he gets his exercise, he goes straight to his cage to chill. He prefers staying in there over sitting in the living room or on my bed and he seems to choose his cage just as often as a few of his other favorite spots in my room despite being in his cage for hours when I'm sleeping or not home. The decisions that he makes like that, let me know that he is happy with his cage.

A bunny must be let out of his cage as often as possible though because although I love hanging out in my room, of course I want and need to get out of it a fair amount of time and a bunny is no different. Also, if the bunny has space to jump, stretch out, eat, and poop, then he shouldn't mind chillin' in his cage when he has to. If he looks relaxed and lays on his side or back, that is a sign he's contented. :) Peace.

Answer 2

if your parakeet is making allot of chirping sounds around you, it usually means it's happy

if your parakeet is hiding or making a loud, angry, squawking sound, it usually means to go away or she/he doesn't trust you and that means you need to gain it's trust

Answer 3

If it is relaxed and calm then it normally will be singing or grinding or clacking its beak.
