I see Lincoln's sparrows fairly regularly this time of year - but I'm down in Mexico! However, given my recently vast experience with Lincoln's sparrows (much more than in Vermont), I have to differ and suggest that Dave's sparrow is a song sparrow. The heavy moustach marks, bolder chest streaking, and lack of warmer background coloration on the chest and face regions lead me to that conclusion.
In general, I have found it interesting the number of "northeast kingdom" species that overwinter here, while I don't see many of the other Vt summertime residents. Orange-crowned warblers and Wilson's warblers are two of the most common warblers here in the high-plateau region of Mexico (State of Hidalgo). It is interesting to see them mix with Vermillion flycatchers in my yard!
