My cockatiels are outside in a screened house. How cool can they stand it?

At what temperature should I bring them inside? At what temperature will they get sick and die? I also have some Quakers. They live in the wild in New York City and in the Dallas, Texas area, so I know they can tolerate pretty cold weather. I will still be bringing them in, of course.My cockatiels are outside in a screened house. How cool can they stand it?
i agree with the above statement and do ask if you do keep them outside anyways, to provide heat lamps for them!My cockatiels are outside in a screened house. How cool can they stand it?
Hello. That is not a good idea (to keep them outside) for many, many reasons. Not the least of which is that Tiels are very social and very people oriented. They need to be inside with their families and need to be interacted with as much as possible and need out of cage time to spend with their people. To answer the temperature question, of course they can ';survive'; outside, otherwise there would be no more of them still living wild in their native Australia. They can stand a fairly wide range of temperatures but sudden changes of more than about 10 degees, they do not handle well at all. All the birds in this country have been captive bred since at least 1991 or 1992 as that's when the import of exotic birds was outlawed. They have been captive bred and for the most part, indoor birds for too long to put them out like that. All that aside, there are serious health issues to be considered, including some predators that can get into almost any enclosure, not the least of which would be snakes, that would attempt to swallow them whole. Any predator, even attempting to get to them could frighten them into a heart attack. There are also all the disease and parasites carried by wild birds and the threat of a bite from a mosquito carrying the West Nile Virus. We can survive that. They cannot. If you have, or are considering getting any Tiels, (or any other type of bird for that matter, and for the same reasons,) I'd strongly urge you to accommodate them inside with you, or to wait until that is feasible for you.
