Not sure why it is. Bonus actions should be listed after actions as Reactions are. This is a good reason (among others) to transcribe them into a format you can use at the table. I find the transcription process helps to cement the aspects of the creature in my mind. I can also add a brief description too.Just curious why most of the monsters I've seen that have a Bonus Action option have that option hidden up in the traits section of the statblock. I often end up forgetting about them because they don't have their own section, like Reactions do.
