I only have males, so I can't say if the females make some sounds at times.
Yes, it all depends on how many males you have and your lighting schedule.

My males usually croak around noon, stop and start around 8 or 9 right after I turn their UVB off then sing me a song through the night, they usually croak all day if its storming outside.

Like Pivet stated before, they usually do at random times to re-assert dominance, usually the largest will do this. It sounds like a fast pased croaking mixed in with the dominant males croaking.
