As my grandmother always said, “Horses sweat. Men perspire. Women glow.” How do we avoid this sticky situation? Kids run through sprinklers and adults head for the air conditioning, but what do the birds do when the thermometer climbs? They don’t sweat they can’t take advantage of the A/C. However, that doesn’t mean they just sit there and bake, either.
Because birds have relatively high body temperatures—a Golden Kinglet’s temperature was measured at 111° F!—it’s critical that they avoid getting too warm. Many essential proteins begin to break down at temperatures just a few degrees higher, so overheating could easily be fatal. Thankfully, birds have all sorts of ways of beating the heat.
