How do the baby wrens get out of bird house?

Baby wrens are born inside the birdhouse, and they stay there for about 12-14 days until they are ready to fledge. When they are ready to leave, they will start by perching on the edge of the birdhouse. They will then flap their wings and jump out of the birdhouse. They may not be able to fly very well at first, so they may fall to the ground. If they do, they will usually be able to climb back up into the birdhouse. After a few days, they will be able to fly well enough to leave the birdhouse for good.
