It's interesting how places on earth that we're not familiar with can be so different from what we've always assumed, isn't it?
I have a cockatiel, which is technically a grass parakeet from Australia, a land we also often think of as being always warm (not to mention assuming that this "exotic bird" was only accustomed to existing at warm and humid temperatures). But one of the things I learned is that in their native land, they're actually exposed to temperatures below freezing, even though in captivity these are not temperatures they're acclimated to.
and it gets colder up there, but I wouldn't think *snow* when I think of Africa. My sister lives in Arizona and it's 120 degrees there now, but in the mountains it's in the 70's. But this is summer. She doesn't go up to the moutains in the winter. Will have to ask her about the temps then.
Hope all is well by you. How's the house? Everything going ok? And Mr. D? How's his tail?
