On my way into work today I saw this bird chilling on a fence in the train parking lot. I'd love to know what it is. Location is the Bay Area peninsula.

Looks like a Cooper's hawk, see here.

Maybe a Sharp Shinned?

It's either Cooper's Hawk or Sharp-shinned Hawk. Looks like Cooper's to me, the ends of the tail appear somewhat rounded, with a white terminal band on the tail. Also looks too big for Sharp-shinned, but that's difficult to judge.

Yep, it's one of those Accipiter hawks! +1 to @jkent.

It definitely seemed more crow sized which from the links would make it a cooper's hawk I think. Thank you so much!

Cooper's & Sharp-Shinned are notoriously difficult to differentiate, but I would also tend towards Cooper's given the shape of the head.

Oh, and their primary food is other birds, so it was probably looking for starlings, pigeons, robins, or other common urban/suburban birds.

For future reference, the Audubon Society has a Bird Guide App which helps you identify birds by habitat, size, behavior, physical description, wing and tail shape, and bird category.

I can't say it would work great on this feathered friend because it's not doing anything, birdwise, but it's a good start. Using your pics, it gave me 11 candidates, of which, IMO, an immature Cooper's Hawk seems like the closest match.

The generally even, bland coloring generally indicates a juvenile, to me. It should become more distinctive as it matures and starts signalling its sex.

Forgive me, but this question made me miss rtha. I bet she would've chimed in.
