Why not a Song Sparrow. Streaking doesn't look very fine and I see very little buffiness.

It has too fine streaking, too much buffieness, and a pink bill where as a Song has a gray-ish bill.

Ridgway's rail, Western Grebe, Horned Grebe, Lincoln's Sparrow.

The sparrow is almost certainly a juvenile Song Sparrow. It's not an adult of either species based on the face pattern and the nature of the streaking below. Lincoln's don't show up in Marin county in numbers until September (the latter half of August has a few records) but those aren't going to be in juvenile plumage.

Hmmm. I guess I can see that.....Still think Lincoln's but I don't want to argue.

Juvenile Lincoln's and juvenile Songs are very difficult to distinguish, actually. Of course, usually the parents are nearby, which helps.

I agree with psweet - juvenile Song Sparrow.

Agree with Horned Grebe ... I made this comparison between Horned and Eared for myself a couple of years back ...

Yea, I'd go with Song Sparrow for that last one. Pretty much a perfect match for a juvie heermani group

Decidedly a juv Song -- the streaking on the chest is over white, not buff, and juv Lincoln's will have molted out of juv plumage before they get to coastal CA.  The big grebe's bill looks a bit too orange for Western, though that appearance could be a photographic artifact.  Certainly, the plumage looks like that of Western and not of Clark's.  However, hybrids are not rare, and there are also back-crosses.  Or, at least, birds that look like the result of back-crossing.

Is that when they hybridize and then the young breed with one of the original species?

Thanks everyone for the info. If I recall there were a few adult song sparrows hanging around the day I took that shot so Juvi Song sparrow would make a lot of sense.

Here's another shot of that Grebe if it helps.
