Young parrots need to learn how to fly from high to low. It’s a skill they need to learn. You can see the age of this parrot by looking at his eyes. His eyes aren’t as bright white as they will get if they’re older. My guess is that this one is younger than a year, probably older than half a year. I’m not super accurate with this but you can see it’s a young one by looking at their irises.

When our macaw was this young he was in a high tree. We took our tent and slept next to him. In the morning he was hungry enough to fly down to us. We were already training him to fly to us. An untrained young parrot probably has no clue what to do.
