Rufous-collared Sparrow (Zonotrichia capensis)

I first saw this small sparrow in Ecuador before I knew I was a birder. It caught my eye and I fell in love with them. This photo was taken in near-zero temperature in the high Andes Mountains of Columbia, in February 2022. This explains why it is puffed up into a sphere. I didn’t notice the leg band on the left leg until we returned home and I cropped the photo.
