Dark-eyed Junco
Junco hyemalis
Notes:

Juncos visit every fall. They don't always stay all winter. But it's fairly common to see them around the feeder in winter.

They disappear and head north each spring.

The old Lakota was wise. He knew that man's heart away from nature becomes hard; he knew that lack of respect for growing, living things soon led to lack of respect for humans too.
