This appears to be the same Harris's Sparrow (adult winter plumage) that I found here on December 23rd, 2014. Mary & Nori (dog) & I watched it feed and come and go the whole time of our visit late this morning. It inspired me to bring out my digiscoping setup. It's tough to track and focus little birds at close range, but I like how sharp the photos can be.
The seed can is almost empty, a sign of lots of human visitors to the patch, probably mostly due to this bird's visit. 150 pounds of seed in 3 weeks. Thanks to Karen Zook at Yakima Valley Audubon Society for reimbursing the seed cost.
