American tree sparrow at Lake Meyer Park IA 2K3A3707
We know that winter weather is right around the corner here in the Driftless region when the American tree sparrows arrive after leaving their nesting areas in the high arctic. Historically, they were the only native sparrow that stayed and could survive northern Iowa's terrible winters but in recent years a few other tough sparrow species have been able to pull that winter resident trick off too - thanks to global warming.
