Brewer's Sparrow: Small grayish-brown bird in the Grasslands

Brewer's Sparrow: When I saw this little bird, it looked vaguely familiar. But its markings were far too subdued to be the Clay-coloured Sparrow it vaguely resembled. But Brewer's Sparrows don't have strong plumage contrasts. Their back and face markings are soft and indistinctly streaky, and their overall colouring, a gentle grayish-brown, with no bright white supercilium/above eye stripe or obvious pale central crown stripe.
