Hi. Step back and take a deep breath!
You did fine using the corn starch, next time use cayenne and some light pressure, the bleeding will stop even faster. If you have orange juice I would offer it to your bird. Why orange juice? If you have given blood before they always give you orange for the calorie and sugar boost. I would let the bird sleep on his regular perch, he will be less likely to bump it on an adjacent cage bar.
As a precautionary measure locate some Kayro for dextrose and some children's plain pedialyte. No need to give these to the bird now but you have it in case you need them.
Keep us updated.
