I had the same problem with our bird. I just kept offering seeds and pellets until she finally started picking at the pellets more. I kept them in separate bowls and switched their location a few times, I even tried mixing pellets in with her seeds. Eventually I went back to a bowl of each and after a little while she started eating both. She still eats more of the seeds than pellets I think, but she has started eating them at least. I know some people have had luck with just taking away the seeds all together and letting them "get hungry" and they eventually start eating the pellets but I am kind of afraid to do that.
One recommended method is to mix the seeds and pellets (say 25% pellets, 75% seeds) to start for a few days and then slowly over the course of a week or two, increase the percentage of pellets and decrease the percentage of seeds until its 100% pellets. A drastic switch can be hard on birds (although it does work for some!). Good luck, they will be much healthier on pellets. seeds can always be a treat on occasion for most parrots.
I finally made the switch earlier this year with Baby, a 26 year old nape. I tried numerous times in the past and any mixing of seeds with pellets never worked for me. You should fill a bowl with pellets, remove all seeds, and leave that in for the entire day. If you see the bird isn't touching it then provide a small amount of seeds at the end of the day for a short period of time. I experimented with different pellets and wetting the pellets to get them mushy. I thought my bird would be into the fruity colorful pellets but he wants no part of them.
When he finally tried the Roudybush pellets I think he realized that he liked them. If you do wet them I would not leave them in long that way. I changed the bowl a few times a day. When he really started eating I stopped all seeds and phased out wetting of the pellets. He hasn't had seeds since. I don't think a bird is going to starve if it doesn't eat for a couple of days. But you should monitor the droppings. After a few days my bird's dropping became a light grayish brown and didn't look to dry so I knew he wasn't starving. I really believe he is healthier since the switch and it doesn't cost much more than the seeds I was buying. Good luck.
I had alot of suggestions when i asked about the switch and some of the ones that seem to work the best was coating thier favorite fruits in crushed pellets so they can get used to the taste, and for the extremely picky birdie i mixed some pellets with some organic baby foods of my birds favorite treat flavors IE sweet potatoes or something, but only do this one occasionally and in extreme cases or some birdies will decide they prefer only the wet food.
