Thanks so much for the info! I will be getting my bird in mid-December (its finally decided, hooray!!) and I live in Canada. So for around 6 months of the year its impossible to keep a window open or take a bird outside because of the temperature. Otherwise I wouldn't really consider it...
I will see how my finances go after I get my budgie and decide then, but thanks for your input!

-edit-
ALSO! This may be a ridiculous question, but can you harness-train a budgie? Can you even get harnesses for them? I'd love to be able to take my budgie outside in nice weather... but without a cage if possible!
Thanks in advance x)
Just a young parrot novice looking to learn more. Considering getting a small parrot! (perhaps a budgie, lovebird, or conure!)
