Keeping track of bird lineage

[eKlay]

I'm writing this again cause the first time I posted it errored and I lost it :(

I'm starting to breed budgies again after about 20 years, and I'm wondering if in all that time someone has come up with a good and easy way to keep track of a bird's lineage?

I'm considering banding but I don't know if that's the best way or where to get the equipment.

Any thoughts on the best way to keep track of a bird's lineage?
