1) "They travel by night"
2) "They travel at night"

1) Seems to imply they travel only at night, whereas 2) seems to imply they sometimes/often travel during the night, but perhaps also during the day.

In most other contexts, "at night" is the only possible choice: one studies at night rather than studying by night.

I believe "by night" is an archaic form.
