Yes
Most birds sleep 4 to 5 hours a day. Birds will go to sleep after the sun sets. Birds awaken when the sun rises in the morning.
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.
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.
where do robin birds live?
Birds live anywhere in the world, even in Antarctica. They live in trees, on the ground, in forests, and in deserts. Birds can live anywhere and can even be kept as pets. Most birds migrate to warmer areas when the weather starts to get chilly. To answer your question short, birds can live anywhere.

penguins are birds that live in the antarctic
Me not know who live with all birds
Of course. Advanced life forms always need sleep. Some birds rest on branches or in a nest. Others, like the albatross, sleep for a couple hours in the air as they glide.
