I don't have a parrot, but I would love to someday! I didn't realize you could take them outside. I thought maybe a sun room, or a porch would be safe, but outside!!! How wonderful that you can let them enjoy outside without it escaping!
Only a few of my parrots are full flighted. Those ones only go outside in a cage. My greenwing is clipped and I cautiously take her out realizing the huge risk I am taking. Even though a bird is clipped, they can still fly.
The safest way to take them outside is using a harness.
