But as promised, I do have some photos of more juvenile birds that we have been getting more and more of.
This juvenile Lark Sparrow looks like a lot of young birds, brown and spotty. He still has the cheek patch like the adult, which will later turn a bright chestnut color.

Similar to the Lark Sparrow, this juvenile Rufous-crowned Sparrow is much duller than the adult. He doesn't have much of a rufous crown at all. We found that this guy seems to have been born with a deformed bill that is crossed at the tip. Right now he probably is still being fed by his parents. Hopefully his deformity won't prevent him from foraging on his own, but it doesn't look to be too bad.
