Problematic ID Lincoln's Sparrow at Pacific Commons 2021-03-04

David Yeamans

In this checklist     I included two photos of a sparrow I have called Lincoln's sparrow. It could be mistaken for a swamp sparrow given that Sibley says the two as immatures are nearly indistinguishable from one another. The other option I considered and rejected was white-throated sparrow. I'm seeking opinions. Offline responses are welcome.
