Bird Photography - Hard work!

I went to a friend's place who have a Lorikeet name Chris Murphy. Spent quite a while taking photos. I spent ages trying to get a shot if it in flight (indoors) and found it extremely difficult.
I would appreciate any tips on taking shots of birds in flight - Is it just practice, practice and more practice?
The one in-flight shot that worked:
Managed a couple of nice Macro shots though:
