Vesper Sparrow

I found another new species (to me) in Live Oak Canyon near my home over the weekend. 

The vesper sparrow has a white eye ring; a pale spot outlined in dark  just below and behind the eye; a long dark brown tail with white outer tail feathers; light brown upperparts and light underparts, both with darker streaking; and a chestnut shoulder patch. 

In Roman Catholicism, vespers is an evening prayer of thanksgiving and praise. The vesper sparrow's song is a "combination of clear whistles and trills...often heard at twilight, roughly the same time as Catholic vesper services." 

I misidentified it on iNaturalist, pointed out by several people, but one person was kind enough to explain why my identification was incorrect.
