Once you return to the castle, you can visit Sebastian in the Undercroft in the Defence Against the Dark Arts tower, and ask to learn about it.

Phoenixes were semi-protected from the Killing Curse, due to them being immortal. In 1996, Fawkes swallowed one intended for Albus Dumbledore, causing him to burst into flame and die instantly. However, he then was reborn from his ashes. This makes phoenixes resistant to the Killing Curse.
