Why is the rooster crowing at 1am everyday?

1am everyday he crows. He doesn't normally do this but he has been doing it every night for the past 2 or 3 weeks and I am trying to figure out why because it happens to be my bedtime lol.

Sometimes he will wake up and crow if there is a light on near the coop or on rare occasions if the moon is full but all the lights are off and the moon isnt full. I went out and looked for lights on at a neighbors house or something but there isn't one.

There also haven’t been any predators around that I know of. I even set up a trail camera just in case, but nothing. No loud noises either.
