What a good girl! For an English budgie, I think 41g is on the lower end of average, but weights can vary a lot from bird to bird. I'd recommend weighing her more regularly for a while to establish her baseline (will probably be a little off weight just now if she's been not eating in her grief). Once you have a pretty good idea of what her normal weight is, you can switch to monthly or just weigh her if you suspect something may be wrong.

If you have a bird who's willing to step on a scale for you, weight can be a great indicator of their health, since we get so few indications from them.
