Thanks for reaching out about Mario and including photos. Is Mario an older parakeet (5+)? Typically this is seen in female parakeets that are ovulating and the cere becomes hyperkeratotic (thickened scales). If this is a male and the cere USED to be blue and now tan/brown, there is a concern that a testicular tumor is producing estrogen, therefore thickened cere. Mites are possible but usually does not appear like this. A veterinary visit is recommended to assess health. Good luck.
