Wow what a request from the little one!:) I don't have any new suggestions but as some of the other moms mentioned, try the sheet cakes with decorations and airbrushing. I once saw (i think at joann fabrics) little decorative cages with birds (about 5 inches tall) inside of them and so maybe you could make a nice round cake and add this to the top. Shape cakes may be easy for some but reading one of the postings below on how to cut it, it didn't make me want to give it a try. :) I would have someone make a great big colorful parakeet cake for less (sams/costco/jewel) and enjoy my day with little birthday superstar.
