This is a two part question, I'm not referring to drafts or the danger of drafts, just temperatures:
1) What is the ideal indoor temperature for captive parrots? What temperature is too cold for a parrot to be in 24/7?
2) What temperature is too cold for a parrot to be taken outside (unprotected, not in a covered carrier)? I can't imagine taking my parrot outside during the winter months (currently -45 celcius/ -49 fahrenheit ). I've seen a few videos of people that take their parrots outside when there is still snow on the ground, I'm sure it's not as cold as -45c but it must still be cold out for the snow to be on the ground! Is the drastic temperature change from indoors to outside in the colder months too much for a parrot? Or am I just being overprotective? What temperature difference is too much to take your parrot outside? Is a difference of 5-10 degrees (celsius) ok? Or how about 20 or 25 degrees?
Below are some of the videos I found with parrots out in the snow. The last one states that it's a very warm January day, about 70F. Maybe all of the videos are taken on unusually warm days? Whether or not it's a warm day, the B & G macaw in the second video is walking on the snow! Is that not way too cold for it?
