White-Breasted Nuthatches

Theere are two possible species listings for White-breasted Nuthatches in Archuleta County Colorado. One is listed as "interior west". How do I determine which nuthatch I am seeing? Does ebird define these subspecies and if so where?

Here is one good source of info on Colorado White-breasted Nuthatches:
http://cobirds.org/CFO/ColoradoBirds/InTheScope/53.pdf

Vocalizations are a very good way to identify them, and you can explore differences at http://www.xeno-canto.org/

In Archuleta County it would be the "Interior West" form. The "Eastern" form is associated with the Plains. There is some overlap in occurrence or near proximity between the two forms along the Front Range. And on the plains of CO the Interior West form is also a rare possibility at times. You can take a look at the Species Maps in Explore Data to see where both forms have been reported, zooming in to see the details. But in the western part of the state it is the interior form that is expected. It is fine to just report your nuthatches to the parent species (i.e., not designating a form) if you have not actually identified them based on calls or appearance.
