Congratulations on your new arrival! It's always exciting when you bring a new budgie friend into your home
If the cere is a clear, pearly pink, you most likely have a young male! However, reading through the links provided above will help you to confirm that; you can also post photos once s/he starts to settle in.
If you have any questions after reviewing the links above, let us know! Now that you have your new friend, all the research you've done so far surely will pay off
I originally wanted a parrot, I realised I wasn't ready for that commitment, and absolutely fell in love with researching all about budgies. I was obsessed, and spent all my free time for a few months learning lots about these adorable little birds, much like you did
Unfortunately, I missed the bit about not buying from big-box pet stores, so I got my little girl from PetCo, but it was love at first sight! I had all these silly expectations, like "Oh, I want a male! A violet cobalt male!" but all of that flew out the window when I saw my Mallorn. She was the only budgie in the enclosure who seemed to see me, and when she walked up to the glass and looked at me curiously, I realised she definitely was my budgie!
I've had her for five years, and she and I are now inseparable. It's been a crazy five years, (no doubt!) with plenty of mischief, frustrations, joys, triumphs, and scares, just like all budgie owners experience.
So, I wish you luck with your own budgie journey, and I look forward to meeting him/her soon!
