My bourke hen came with her parents. She wasn't a breeder, but she did lay eggs. She was also never tame or friendly...
She never was interested, nor did I ever really attempt to do so... even when I was working with the budgies on gaining their trust, which then led to me working with the cockatiels... and working with tiels did create interest with Sylphie, the ARN.
My bourke hen just never showed any interest... She was never aggressive, never bit out of no-where, and honestly, her bites in her older years were nibbles. aka.. pathetic attempts at a bite.
If you want to enjoy a calm and peaceful bird that may enjoy sitting on your shoulder but isn't *really* a physical bird, then a bourke can be a great companion!
If you plan on clipping the bird and forcing it to sit with you, then IMO, a bourke is *NOT* for you. I can not, nor will I, recommend clipping a bourke! I feel it's akin to clipping finches! On top of that, clipping a bird is not a trust-building thing...
If you are willing to have a *LOT* of patience, and you can put her into a large flight cage (i.e. something along the lines of 28 x 18 x 30, or larger), then sure, go for it!
I don't currently have any bourke parakeets, but I miss them! I love listening to them chitter chatter, singing, and heck, even flying! They are charming little birds!
