Description of the Bird
This White-throated Sparrow was a white-stripped adult with bright yellow lores. It's plumage was typical for the species in breeding season. I will leave it to the photos to provide a descriptor of the details.
Steve and Deb found the bird at first glance outside the dining room window about ten feet away and about four feet below. The White-throated Sparrow usually fed on the ground taking sunflower seed, cracked corn and red milo. It also foraged in Engelmann Spruce and Sub-alpine Fir. It fed on the ground along with Pine Grosbeaks, many Gray-headed Juncos, a single Song Sparrow, Steller's Jays, two Band-tailed Pigeons, Mountain and Black-capped Chicadees. Also present were three species of nuthatches, three species of woodpeckers, Broad-tailed Hummingbirds, American Robin, American Crow, and an American Dipper singing in the stream 36 feet away.
We did not hear vocalizations from the White-crowned Sparrow, nor did we see agonistic actions toward the other birds.
Similar Species Discussion
The bright yellow patch in the lores separates the White-throated Sparrow from the White-Crowned Sparrow and the Golden-crowned Sparrow.
Previous Experience
I have seen and photographed White-throated Sparrow feed along with White-crowned Sparrow and Harris's Sparrow (three Zonotrichia) at our home outside Palisade, CO.
