Thanks! I know the bill length will give some insight between the hairy and downy woodpecker, but not certain myself.

Here are two additional images of the first woodpecker.

Taken yesterday in Fremont, CA. I used my phone for thus one. Is the first one a downy woodpecker or hairy woodpecker? 2nd one should be Nuttall. Thanks

Yup. Agreed. Thanks!

Thanks, I am curious to see what others have to say.

Taken today at Hayward Regional Shoreline, California.

Sorry, didn't make it clear the first time ;). I have seen tons of red-shouldered hawks but not red-tailed hawks. This is the first time I have photographed a red-tailed hawk to document as photographic evidence ? Red-shouldered Hawks are amazing. This is one I captured recently

Thanks! I've seen tons of red-shouldered, but this one is the first I have photographed. I've probably seen some outside, but didn't bother to identify them or have a binocular handy.

Spotted this guy flying high above my backyard. Pretty sure it's a red-tailed hawk (SF Bay Area, California). Light Morph? Haven't got one in my collection yet (eBird) ?.

Yep. Turkey Vulture.

Looks good for Field Sparrow.

In your fourth image, you can see the bill is much longer than the the head length (kind of what you expect for a greater instead of lesser). Also you want to look for a slight upturn of the bill for the bird. I can kind of see that in the image. I would say greater as well.

Agreed. Domestic mallard fits the field mark

Spotted this female bird at Coyote Hills, California today. My guess is Tri-colored since the dark brown and streaky plumage field mark is quite visible. eBird states that Red-winged blackbird females have warmer tones for their plumage. Can anyone confirm?

You meant Cooper's Hawk and Sharp-shinned Hawk? I have trouble with those as well
