I have a 9 month old Moustache Derbyan Hybrid so I'm not sure if this will be too much of help but this is my experience.
Pros: Such sweet birds! Seriously love hanging out with you and being with you. But they can also be very independent and appreciate their own time to play with their toys or do whatever they seem fit! So goofy, funny and playful. They are like little clowns and love goofing off and being silly! THE BEST at giving kisses. And they smell amazing
Potential to talk. Mine talks, and his voice is the sweetest thing I've ever heard. They're overall pretty quiet when given lots of attention, but there are some exceptions! Perfect size for sitting on your shoulder a bunch and chilling out
Cons: Their call is pretty loud for a smaller bird! It can be ear piercing for sure. This may not be a con for some people but I thought I'd add it- they definitely aren't cuddly birds! Their feathers are different than conures and cockatoos and other birds that love being petted. (I'm sure they can tolerate petting or even learn to enjoy it with persistence and training) but I'd say for the most part they're not very hands on birds. They CHEW like crazy. They go through wooden toys so fast that they're like beavers lol. They can be extremely stubborn and they have very bossy personalities.
I see you've already gotten one and I'm so happy for you
they're seriousy incredible and I'm sure you will enjoy every single second of him!!
