Birds of Columbia County (as of 09 May 2014):
According to the East Cascades Audubon Society (ECAS) 324 species of birds have been recorded in Columbia County. Here (.pdf) is a link to the ECAS checklist for the County. Here is a descriptive guide to the county maintained by ECAS. It uses large portions of this guide as a reference.
eBird has 230 recorded species.
Oregon Birding Trails has a Trail and Site Guide (pdf) that covers parts of Columbia County. It is in the Willamette Valley section under the Columbia Loop Guide. The Guide has specie accounts but no count totals as it is not County specific.

An accounting of the phenology for migrating birds in the County is beyond the scope of this guide. However, it is possible to get a reasonably accurate sense of arrival and departure dates by looking up the County list on eBird. There one will find each of the 230 birds that are recorded for Columbia County in eBird. The occurrence of each species is shown for each week of the year. It is a very intuitive set of charts and a birder interested in birding the County will benefit from this data. This data set should be referenced for the dates specific birds are present before heading out to look for a target bird from a list.
Here is a data based accounting of Northern Willamette Valley Phenology. And here is a narrative based account for spring arrivals for the Willamette Valley in general. And this link will take you to a few calendar based accountings.
