Yes wood ducks sleep in trees.
Dragonflies usually sleep on any avaible surface (such as a bush or tree)
carefully pick up the duck with rubber gloves and gently place the duck back in the tree where it belongs.
Many birds sleep with their heads twisted into awkward-looking positions. While a person wouldn't be able to sleep that way, for a duck it is natural and is comfortable.
The McDuck's
The tree kangaroos sleep and live in the trees. The animals sleep during the day and are awake during the night hours.
In plants and tree's, basically any where sheltered that protects them from predators and the weather.
I begged the differ, I have a mated pair of mallard ducks on my property that feed in the river and fly up every evening and sleep in our trees in the morning. I didn't think it was possible due to their webbed feet but nature proved me wrong!

You get a dead chicken, or duck. But you can get a chicken/duck tree, depending on the season, lighting, and waterness.

Monkeys sleep in the tree tops, as it would be too dangerous to sleep on the ground.
