Parrots do adapt to colder temperatures as last weekend when I was in Pigeon Forge I went to Parrot Mountain and it was only in the upper 40's for a start to the day and the birds were outside on their perches though they do go inside at night when they close and November is the last month they are open until spring. There were lots of macaws, cockatoos, amazons, conures and multitudes of other species, we got to feed some of them and one Mtoo climbed on for some cuddling, I would recommend anyone who lives anywhere near or travels to Tennessee to pay them a visit, it was worth the trip, I will probably return for another visit in the future.
