Backstory (can skip to last night): We originally adopted Scott and Harley as potential cage mates for our first gcc Pistachio. We had placed an ad in Craigslist and received two answers. Pistachio hit it off with Scott right away. (This is before we'd heard of quarantining.) When we brought Harley home her whole body was covered in pinfeathers. We introduced her to the boys and she allowed them to preen her for about 5 minutes before she'd had enough and climbed away. We ended up keeping both, Harley in her cage and the boys shared a cage until 'Stachi was taken by a hawk during one of our walks the following year. Scotty was so upset by the loss of his friend that he started barbering his chest feathers. We tried to reintroduce him to Harley, but he charged at her so we didn't try again. When we're home everyone's cages are open. Scotty hangs out on the top of his cage to be as high up as he can and Harley likes to climb around and explore when she's not sitting on eggs. (She only lays 3-4 times a year but sits on them forever.) About a month and a half ago, Harley wandered into the bottom of Scott's cage, shredded up the newspaper at the bottom and made herself comfortable. Her cage has a grate, so I guess she likes his better. At first I kept trying to move her back to her cage but she kept finding her way to the bottom of his. Then I tried putting him in her empty cage, but when we let them out, he'd climb back on and in his cage because it's taller. He is a "top 1/3-er" and doesn't use the rest of his cage and she only comes up to eat (and he backs away and waits until she's done) so they have been technically co-habituating for the past month even though they don't interact. I was really worried about it at first and even slept on the sofa for the first few nights in case there was a squabble, but nothing ever came of it. Last night I was giving Buzzard his night-night juice (a little juice diluted with lots of water) and realized Scott's cage wasn't covered all the way. I said, "Uh oh, Scotty is probably watching and wants some juice." My step daughter looked over for me and said, "No, he didn't even notice. He's preening Harley." Say what? She said it like it was the most normal thing in the world! There they were, cuddled up on the boing, both sleepy-fluffy with Scotty preening Harley's head so gently. I wanted to take a picture but didn't want to damage the moment. Hopefully this is the start of something wonderful and I'll have many more opportunities to take pics later.
