What changes the supplies answer
Buy a gram scale before the bird comes home and make weighing part of the routine.
Use a baseline
The normal range for a budgie, cockatiel, conure, or macaw is not the same. Track the individual bird.
Train the behavior
A perch, bowl, or small carrier on the scale can help the bird stand calmly for a reward.
Watch trends
One odd number may be setup error, but repeated loss, sudden loss, or loss with illness signs needs vet advice.
Best habit
Weigh before there is a problem so you know what normal looks like.
