OMG, it's the male Thomasina.
I get the death glare whenever I give attention to any other animal, and I've made jokes while looking at birds at Petco that I'm not allowed to bring home any bird larger than a budgie (budgies and finches stay in another room of the house, where she doesn't go), lest she find a way to escape her cage and claw my face off. She used to go into full "You know you wanna give me attention, mama" mode upon seeing me talk to Cheerio the cockatiel, and when he passed on, I looked at her and jokingly said "You got your way."
She's still not completely hand-tame, and I doubt she ever will be at the point where I can safely let her out of her cage, but she's come a long way from being afraid of everyone that came near her enough to throw herself off perches and bloody up her wings each time.
She wasn't happy today, because the living room was changed around to accomodate the Christmas tree. Her stand and my chair ended up on the opposite side of the room from where they were. She made her displeasure known, especially when she found out she could no longer sit on the water dish to receive and dunk her favorite popcorn, because the cage was facing the opposite way. Heaven forbid she actually have to make the short trip from the food to the water dish each time!
After several minutes of her flipping around her cage (she climbs from her food dish to her water dish, grabs the top of the cage with her beak, pulls herself up, goes across it upside-down, then repeats the process to get back to her food dish), I talked over moving the tree again with my mom, and the brat-bird got her way.
I was concerned about having her cage so close to a heating vent, in case smoke or something wafted up through it (which has happened before). After everything was rearranged, the spoiled princess was happy again and all was peaceful in the kingdom.
