These little buggers live (I think) in a dying Oak tree in the front of my yard and are very busy along their trails into my house. I live in Napa, California and it is early spring. Any idea what type of ant they are?

We believe, because of their large size and their location in the tree that these are most likely Carpenter Ants in the genus Camponotus, though we do not have the necessary skills to identify them based on their anatomy. They somewhat resemble this photo of Camponotus clarithorax from California posted on BugGuide. General information on Carpenter Ants can be found on the information page for the genus on BugGuide.
