An excellent resource for the entire state of Washington is the ABA’s A Birder’s Guide to Washington. An on-line version with constant updates is sponsored by WOS and ABA and is available for anyone to view. The published version is an excellent guide to keep on hand!

eBird is also an excellent reference for hotspots, current and historical sightings. If you are not familiar with this citizen science project from Cornell’s Lab of Ornithology, they have excellent tutorials.
Vancouver is located in Clark County, WA, bordered at the north by Cowlitz Co., and to the east by Skamania Co. Portland, OR is right across the river to the south. Portland Audubon has some great resources as well.
Vancouver has some great birding opportunities! Some of the most popular areas are included below, but they are definitely not the only local areas to visit! Most of the area’s expert birders are quite willing to volunteer their time to take out-of-town birders out to their favorite hotspots or lead area field trips.
