My late wife had several parrots. Over a number of years we had a Amazon Double Yellow
Head, Amazon Lialac Fronted, a couple of Green Wing McCaws and an African Grey.
We lived aboard an cruised with the African Grey. We had an
acrylic (no rust) sleep cage build which was mounted in a
cabin below. It was fully enclosed
acrylic with air holes up high so no cage mess could exit the sides. Slide out tray for
cleaning. Space for perch, toy,
food,
water.
During the day the Grey hung out on a perch in the full enclosed
cockpit. We just hosed out the
cockpit each day.
A totally enclosed cockpit is important if you want to keep the bird uncaged in the cockpit. An escaped domesticated parrot wont likely fare well...especially since they cant swim. They can flop around in the water for a very brief time...Ive rescued a few, but youve got to be right there when they go in the water or they will drown.
Your bird is smaller so a cage of some sort in the cockpit may
work more conveniently.
If you plan to
cruise with a parrot, be aware that most species fall under CITES
regulations. This can make it a singificant hassle clearing international borders. Way more so that cats or
dogs aboard (we also cruised with 3 cats).
