Top is juvenile ( grayish banded tail ) and bottom is adult ( dark eye, solid tail. )

Well, there's black spotting on the white sides of the tail, so that makes a bill length call irrelevant. 😉

American Pipit.

Looks like an American Woodcock.

Unfortunately, no way to tell on this type of feather.

Same here.

Sounds like a Bewick's Wren. Their song does resemble that of a Song Sparrow.

Yup.

Looks more brown and streaky to me, like a female Red-winged Blackbird.

News to me about that bird being an escapee. I observed him for a while. I thought maybe he dispersed from the Jacumba population.

Looks good for Red-tailed Hawk to me. You're mostly going to see Red-tailed there now, along with a few Red-shouldered Hawks, Bald and Golden Eagles, Cooper's Hawks, American Kestrels, and Prairie Falcons. As Fall fades into winter, the Ferruginous Hawks, Merlins, and maybe some Sharpies show up. There was a long standing Harris's Hawk in the neighborhood just the other side of the airport from there. Not sure if it's still there or not.

The combination of strong complete eyering, grey head, and bright yellow throat and undersides makes me agree with Nashville.

I believe your question was answered. Obviously you had some doubt about what it was, or you wouldn't have posted it. Keep looking, maybe you'll find a rarity today. Fall migration is the best!

Red-tailed hawk for me. The wings don't look long enough for a Swainson's Hawk, and Swainson's usually has a bit of white on the forehead.

Brown-crested for me too.
