1-3) based off of that one owl house scene Birdie was such a trouble maker in her youth. she has the deadly combo of twilight's intelligence mixed with rainbow's love for pranks and mischief. she alone aged poor Cheerilee like 20 years
4) ok so someone during artfight pointed out that ive never actually drawn birdie using magic. which is… incredibly weird, because ive always believed each of the twidash kids would be incredibly magically talented. Birdie doesnt particularly use her magic abilities much. she tries to hide from her "position" as a princess, and her magic is included in that. she just wants to blend into society as much as possible.
5) this was meant to go in the spike dump from a few months ago but i forgot it oops lol. although he has a lot of…angst at first at the idea of siblings, he's actually the best big bro ever.
6-8) Owlowiscious Jr is Birdie's lil goofy pet, and her best friend. most of the birds that she cares for are with the intention with release back into the wild — Junior however was orphaned as a baby, and is now imprinted onto humans and cannot be released. He was originally living with Fluttershy, but he took a massive liking to Birdie and so she took him home as her own.
Junior is an adorable, loyal fluffball, but he is not the smartest. Birdie has tried to train him to carry out some of her schemes/pranks, but he's just not that interested. He is simply baby. he want cuddles
