I live in southern NM and we have had extremely cold overnight temperatures for about a month, I’d say 10 degrees colder than normal, the days are still about the same it is 75 right now.
I’m in southern Arizona, where we’ve had overnight lows in the 20s for three or four weeks now. This is unusual. I see to it that my local birds are well-fed and -watered including the local cactus wrens and roadrunners.
