I saw Greater Yellowlegs at Delta Ponds in the spring and early summer. Now I am seeing them here again in the fall. I have a hard time telling the greater from the lesser yellowlegs. But after checking "All About Birds" it appears to me this one is a Greater Yellowlegs, unless someone shows me differently. :)

This is what Wikipedia shows as the Greater Yellowlegs:
