The original sentence "After making loud bird calls, the teacher sent Sam to the principal's office for interrupting class" contains a dangling modifier because it is not clear who made the loud bird calls. It is unclear whether it was the teacher or Sam who made the loud bird calls. To correct this, you can move the subject of the bolded clause, "Sam", to the beginning of the sentence, and make it the subject of the clause:
"Sam was sent to the principal's office by the teacher for interrupting class."
