<span style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">I live in Whitefish Bay, Wisconsin and I </span>get a lot of American Goldifinches on my feeder along with sparrows and house finches. Occasionally we will see a cardinal and there are a pair of mourning doves that will eat the seeds the other birds spill on the ground.
This white bird appears to be a sparrow of some sort but it is all white. Is it possible that it is an albino sparrow?
