I am so sorry for your loss. Losing pets can be so hard.
Just in case you want to learn or want to have some closure, there is the option of getting a necropsy done. I have done it for my birds to make sure it wasn't an illness the others could catch. You can get a necropsy at any university that has a vet clinic. I've gotten one done at University of TN Knoxville and Mississippi State University. They are a little pricey, I paid about $70. But if you ever want an in-depth analysis of the health of the bird prior to death, that's always an option.
