Swamp Sparrow

Note only mild breast streaking (blurry centrally) on grayish background. Facial pattern shows a weak eyering and pale buffy-whitish malar (submoustachial), with broad mostly unstreaked gray nape and unstreaked throat. Lincoln's would have a buffy breast and flanks with fine blackish streaking, bolder eyering, and more strongly buff malar, often with a little streaking in the throat and nape band. You can just get a hint of the rufous wing coverts, much brighter than Lincoln's.
