I'm a first time Galah owner, coming up to three weeks now. She's an older bird with issues that we're working through - she's a very shy, nervous bird although we've made a lot of progress. Even at this point though she's packed with personality, does little dances when she wants my attention, enjoys the toys I've put in her cage (although her favourite toys are the ones I cruelly keep out of reach: phone, laptop, tv remote etc).
One thing that might give the impression of being less interesting than other birds that I was very aware of when visiting her prior to bringing her home is that she doesn't fuss for attention if it's not offered. She was in a roomful of Ducorps, LSC and Bare Eyed cocaktoos, and the other birds, clamoured for attention the moment anyone walking into the room: Alice would just sit at the back of her cage until I started talking directly to her, at which point she'd come and play through the bars. Even at home now if I want her to engage with me I generally have to initiate things, otherwise she'll just sit watching me and squeaking to remind me she's there. But if galahs do seem a little less keen to draw your attention I'd take that as shyness/cautiousness, not lack of personality. Personally in the long run I'd rather have a sweet and gentle bird than a petulant attention seeker!
She's also incredibly quiet. The rare occasions we get a full on shriek it's a show of anger or fright - otherwise she has a regular repertoire of cheeps, squeaks and cackles, the best of which are really sweet and the worst of which are at least inoffensive.
The wingspan really took me back the first few times she spread her wings - Copperarabian's right, it's like having a falcon on your wrist! Alice came clipped on one side but she has a couple of new feathers come through, and can get airborne for short distances. Realistically I think we have a way to go before she'll trust me enough to introduce a harness, but it is something I'd love to do and the sooner that wing is back to full feathers the better.
Here she is, anyway:
First video is my favorite. Galahs are such agile fliers and so eager to learn, makes them great for free flying. I think macaws and galahs are the best free fliers, but any species is capable of free flying.
I think rosie is a beautiful bird and so is Kenji. I'd love to see more of them
