I'm so sorry to hear about your loss...!
I know how it feels to loose a much loved pet, as I lost my sweetheart Sydney (black male cat) last summer... !
It will take you a while to get over it; if I may give you a good advize : adopt a new bird as soon as possible. Some Pettalkers told me the same when Sydney died, and believe me, it helped!! I am still mourning over Sydney, but I can give all my love to my two new cats Maya & Inka
