Cyber-Salutations once more...
Basements are definitely the best...believe it or not here in scorched-earth-ville...they are very rare!
I'd think youre rubber boas are one of the best for cold snaps as long as they dont freeze; I think it was you who stated once you'd seen them above ground w/ snow yet in the tree shadows!!!
I once fd. an adult sow rosy boa surface active when it was so cold {Feb @ 4000'] I couldnt drive w/ the windows down!
I dont think rosys could survive mid 90's for long & am gonna have to remain a doubter that rubbers can too., tho I dont doubt for a minute that you have a limited data set indcating they can.
Ive watched any number of desert colubrids go into a pre-prostration panic around 95-101. Only the Coachwhips operate w/a T > ~ 100-102
It does hit the 20's on the open desert; rarely here in the cities anymore...but Ive observed inumerable birds of many orders including falconiformes....alternating perching on one foot w/ the other withdrawn into the puff-ball, so I wouldnt worry about it...tho Id want to give em something other than a metal perch!
BTW...you might have overdone it Richard...I asked for you to share those pacific storms, but lordy...Oak creek went nuts w/ a 15' crest....I suspect if those Narrowheads brumate near the water [evolution can be a counter-intuitive process...]....theyre going to be hard to observe this spring...ohwell if we find they're scarce...we can blame it on the collectors!

John,
Despite living in the bananna belt here in NW Oregon, we occassionally get extreme temperatures that have the potential of killing captive reptiles. I had an ideal situation in my prior residence that was a two story structure with a full basement. I maintained my Rubber Boas in the basement and is was so well insulated that any power loss was of no consequence.
That is not the case in my current single story residence. I have a detached shed in the back yard in which I house my colonies of lab and deer mice along with the boas I maintain for research. Even though I put in a good layer of insulation in the walls and ceiling, I still have to worry about extreme temperature conditions in both the summer and winter.
I have an air conditioner which has takes care of the extreme warm tempertures and have two space heaters at their lowest setting during the winter.
We are currently having the same series of cold storms hit here in the NW as well as in Calif. and elsewhere but so far, without the snow. Our low temperature was at 19 three days ago with a few other days dipping below 32 F. I have gotten up in the middle of the early morning hours just to check but the temperature inside my shed which has not gone below 39 and usually is at 40 - 41 when the outside temperatures are below freezing.
If we were to loose power during a cold snap, I bring the reptiles into the house in aquaria as I have a wood stove going during the winter. I only have had to do that once in the past. Before I got the air conditioner, I sometimes placed all reptile cages on the cement floor of the shed which worked well and placed water soaked damp towels over part of each cage. The thermal maximum for the boa is somewhere around the mid to upper 90's, possibly a little higher.
Have a question for you. What are some of the extreme cold winter temperatures that occur in the region where the Harris' Hawk occurs in Arizona? I have a falconer friend that worries that this hawks might get frostbite on their toes at some of our current cold tempertures. Does it sometimes get into the 20 degree range in the desert regions of AZ during the winter?
