Birds do not sleep in nests as you think, they sleep in the same places they inhabit in the daytime.

They sleep on the nest if incubating eggs or rearing young - the only time they use nests - otherwise many of them find sheltered roosts reasonably safe from weather and predators.
Birds sleep in their nests at nighttime or in birdhouses.

Kiwi sleep during the day. They are nocturnal birds that forage for food at night.
The amount of sleep a bird gets per day or night depends upon the bird. Different birds sleep for different amounts of time based on their habitat and proximity to predators. The amount of sleep they need also depends upon the time of year it is. Migrating birds tend to not sleep as often as non-migrating birds. I know where I live, I don't hear the neighborhood birds for about six hours at night from about 9:30 pm until about 3:30 am. They may not necessarily be sleeping during that time but they are also not singing and calling either.

Nightingale birds sing all night long. There is a myth that they don't sleep, but of course, it isn't true.
They are thinking about where their next meal is going to come from and how to stay safe from predators.

They Sleep at Night.
Night hunter birds, from my point of view, are birds that hunt at night. This includes: owls, night parrots and nightjars. They can also be called 'nocturnal birds'.
