The winter temperatures have been hovering around the zero mark for the last few days. It’s been a mild season up to now so this first Arctic blast has seemed more brutal than usual. While we humans spent our time complaining about it, the animal world took it in mute stride. Of course, animals have no choice other than to deal with it. For active warm-blooded beasts, thermoregulation is the key. External warmth gained through cuddling or southern exposure enhances the ability to keep the body core temperature within safe limits.
I had to admire the thermoregulatory antics of a gang of Starlings hanging around a NAPA auto store on a 4 degree (F) day. The birds were soaking up what they could of the morning sun and assembling along the south-east facing wall. The only good perch was provided by the large plastic “Auto Part” letters.
True to their colonial nature, they were constantly shifting position to allow their fellow birds a place in the sun. Starlings do not have any self-spacing mechanisms so they happily crammed their puffy frames into minimal spaces allowed. The top of the “A” provided the least space while the con-joined “RTS” could accommodate up to a dozen fowl at a time. Taking a “P” took on a whole new meaning in this context.
This location was soon rendered nil as the low angled sun crept westward and caused the eaves to cast a warmth-robbing shadow over the spot. For a few moments, however, these hardy little birds were using their collective wit to avoid freezing their A’s off!
