Seen at San Francisco NWR in Newark, CA. Is this a Yellowlegs? Which one? Last photo includes Mallards for size comparison.

Thanks.

Yes, Lesser. The bill length relative to the head size is a good indicator, as is the size relative to the mallards. Additional points to note are lack of any upturn of the bill and the indistinct markings on the upper breast--that is, lack of definite streaking expected on a Greater.

Thought I'd borrow someone's thread. Is this a greater or Lesser Yellowlegs?

Hi Guy.

Lesser as others have said. Larrys bird, greater.

Check these:

http://www.roysephotos.com/LesserYellowlegs.html

Notice that lesser can have more extensive flank barring than greater, depending on which plumage stage they are in at the moment. The bill of lesser can look a slightly upturned, acctually the lower mandible is straight, while the upper is concave, more or less the same impression in greater.

Is color of the bill an indicator?

I noticed in Jan's pictures that the bill was dark on the lessers and yellow on the greater. This is a Id that I struggle with. We have both and I can't seem to see the difference sometimes.
 
Yes - the colour of the bill is an indicator.
Usaually Lesser has an all dark bill, sometimes, usually in juveniles, a little paler close to the base.
Greater usually has a two-toned bill, especially in non-breeding and juveniles (usually all black in breeding time) The the bill-base usually is greyish, or greyish-blue.
Better then to focus on the other ID characters, but as said, an indicator.
