Hi there and
to the forums!
It's great to have you on the forums
Unfortunately, I'm unable to see the photo you posted of Lemon! If he's a young male, he will have a pink to purple cere, and if "he" is actually a "she", the cere will be whitish and chalky with hints of light blue!
Adult males have dark blue ceres and females have crusty brown ceres when in breeding condition
This may help while you're looking into reposting your photo

Be sure to read through the forums, including the Budgie Articles and "stickies" (threads "stuck" to the top of each subforum for easy reference) to stay up to date on the very best of budgie care, and if you have any questions, be sure to ask as we'd love to help
I look forward to seeing you and Lemon around the forums!
