Pittsburg Rd:
Location/Directions: (45.9009, -123.1408) 15.8 miles from Scappoose, and 0.1 mile from Hwy 47 on the Scappoose – Vernonia Hwy. From this point to Canaan Rd is 13.2 miles, all on gravel roads that vary in condition depending on logging activity.
Habitat and Birds: All but the last mile or so of the road is heavily managed Coast Range Douglas Fir forest in varying stages of harvest. The best strategy is to just get out at promising looking areas. Any place is subject to radical change from year to year. Sooty and Ruffed Grouse, Mountain Quail (rare), Gray Jays, Hermit Warblers, Hutton’s Vireos, Band-tailed Pigeons and Western Bluebirds are the highlights. Possibilities include Northern Goshawk, and Saw-whet, and Northern Pygmy Owls. From the junction with Canaan Rd it is 10.7 miles along Pittsburg Rd into St. Helens and 9.6 miles into Deer Island along Canaan Rd.

(A link to a downloadable copy of this guide is found in the first installment of this series)
Here is a map of all the locations mentioned in this guide.
Gunners Lakes:
Location/Directions: (45.80568, -123.0585) Take the Scappoose – Vernonia Hwy 9.4 miles west from Hwy 30. Turn left onto Pisgah Lookout Rd (not signed). This is pretty much at the top of the pass. On the south side of the Hwy there is a big school bus turn around and parking for the Crown Z trail if one is so inclined to walk the trail. The lakes are about 2.0 miles from the Scappoose – Vernonia Hwy. At this point the road splits – stay to the right to access the lakes.
Habitat and Birds: This whole area can be explored. The lakes can have Wood Ducks, Hooded Mergansers, Mallards, and other ducks possible. The wooded shore lines are great for Woodpeckers, and migrant and breeding songbirds. High elevation birds like Hermit Warblers, Evening Grosbeaks, Red Crossbills and Band-tailed Pigeons have all been recorded in this area. I’m sure Grouse are in the area, I just haven’t encountered them yet. As a bonus I’ve seen Elk on a couple of occasions. May 2014 Update: there is some heavy thinning operations taking place and the road in has been seriously degraded. They have dumped lots of 6 inch minus on the road sot it is pretty rough going. My Prius made it to the lakes but it was dicey in plenty of places and very slow going.

Here is a map of all the locations mentioned in this guide.
Pisgah Home Rd (PL) – 45 species, 3 (6/27/14)
Location/Directions: (45.790581, -122.911799) Along the Scappoose/Vernonia Hwy, 2.5 miles from Hwy 30 take a left on Siercks Rd. Just over a half a mile from S/V Hwy take a left onto Pisgah Home Rd and drive to the top of the hill where it meets Holladay Rd. Continue a short way past this and park opposite Grouse Lane where the pavement ends. Pisgah Home continues as a gravel road/jeep track. Longview Fiber has two gated access points in the area; one along Pisgah Home Rd on the north side of the road (about 1.5 miles up the road) and one a little ways down Holladay. Both are worth a short hike as well.
Habitat and Birds: The trip up starts at Scappoose Creek but is already forested. Just at the start, on the right, there is an old quarry that Belted Kingfishers burrow nest in the face of the cut, at the top where the soil is. (2013,2014) The elevation gain on the trip up is usually enough to bring in some elevational species like Ravens, Red Crossbills, Hairy Woodpeckers, Hermit Warblers, Evening Grosbeaks and Band-tailed Pigeons. At the top there is a regenerating clearcut down slope and an open farmed hill upslope. I usually walk down the gravel road a mile or two through mixed stage coast range forest. High clearance vehilcle could probably drive down the road. Mountain Quail and a Townsend’s Solitaire have been reported from this area.
Pisgah Home Rd.(PL) – 48 species, 4 (6/28/14)
Cackling Goose | Turkey Vulture | Red-tailed Hawk |
Band-tailed Pigeon | Mourning Dove | Rufous Hummingbird |
Belted Kingfisher | Hairy Woodpecker | Northern Flicker |
Western Wood-Pewee | Willow Flycatcher | Hammond’s Flycatcher |
Warbling Vireo | Steller’s Jay | American Crow |
Common Raven | Violet-green Swallow | Barn Swallow |
Black-capped Chickadee | Chestnut-backed Chickadee | Red-breasted Nuthatch |
Brown Creeper | House Wren | Pacific Wren |
Bewick’s Wren | Ruby-crowned Kinglet | Swainson’s Thrush |

Bonnie Falls:
Location/Directions: (45.80429, -122.93734) 4.1 miles west of Hwy 30 along the Scappoose – Vernonia Hwy. There is a pull off on the south side of the road. There is not much here, but County listers will want to make the stop for the American Dippers that have been seen here (2011 – 2013). Woodland birds are also possible. A small patch list has been generated.
Crown Zellerbach Trail – West, Hale Rd. Access:
Location/Directions: (45.82573, -122.95819) About 6.2 miles west of Hwy 30 along the Scappoose – Vernonia Hwy. There is a parking area on Hale Rd. next to the trail, but do not block the yellow gate. Trail heads in both directions but only the section to the east has been explored at this time.
Habitat and Birds: Woodland and riparian birds along an easy paved path with some elevational influence. This is the second place that I know of where American Dipper has been found in the County. This is a very productive short stretch of the trail.
Crown Zellerbach Trail – West, Hale Rd. Access (PL) – 15 species, 1 (5/10/14)
Current list is from one half an hour stop.
Belted Kingfisher | Hairy Woodpecker | Steller’s Jay |
American Crow | Violet-green Swallow | Black-capped Chickadee |
Chestnut-backed Chickadee | American Dipper | Pacific Wren |
Swainson’s Thrush | American Robin | European Starling |

Field Guide to Birding Columbia County (Oregon)
This is the third installment of the “Field Guide”. It is an introduction to the selected birding sites in the County.
This guide will be published in a series of installments:

(A link to a downloadable copy of this guide is found in the first installment of this sereis)
Birding Sites for Columbia County:
This section is divided into three parts: 1) sites along the Columbia River; 2) sites in the Coast Range; followed by 3) a Site Specific listing of the birds seen at each site. Where eBird has a “Hotspot” listing for a site I have used that data. Where no “Hotspot” has been designated I have used my own personal patch lists – where available.
The vast majority of these sites are located along the Columbia River and adjacent bottom lands. In the Coast Range access is limited as most land is in private timber lands. Walk in access is widely available but that puts limits on the territory which can be covered. A third site category should be included; urban and suburban residential habitats. This is partly covered in some sites but could use a more thorough accounting.
Some of the sites listed have not been thoroughly explored and no site species listing has been included. They are mentioned because of their perceived potential to harbor decent habitat for a diversity of wildlife. Here is a map of all the locations mentioned in this guide.
Where Oregon Birding Trails has a guide for a particular location I have added (OBT) to the site name to indicate this.
For this on-line version of the Guide i will cover at least one site per future update and add the site species list with each site to keep things together. There are a number of sites that do not have lists yet. But i’m working on that.

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.
Included in these lists (combined) are 69 rarities (or just difficult birds to find) for the County which should not be expected to be seen:
Ross’s Goose | Emperor Goose | Brant |
White-winged Scoter | Surf Scoter | Red-breasted Merganser |
Mountain Quail | Red-throated Loon | Red-necked Grebe |
Clark’s Grebe | Leach’s Storm-Petrel | Brown Pelican |

County Phenology:
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.

Site Guide for Birding Columbia County – last edited: 10/13/14
(Here is a link to a downloadable copy of this Field Guide)
Overview:
Columbia County is bordered on the north and east by the Columbia River, on the south by Multnomah County and Washington County, and on the west by Clatsop County. The southern County line is approximately 30 minutes from Portland, the largest metropolitan area in Oregon. The western County line is approximately 30 minutes from the Pacific coast.
The County’s northern and eastern boundaries are outlined by 62 miles of Columbia River shoreline. Columbia County enjoys the longest stretch of the Columbia River in the State of Oregon. The Columbia River is a major route of ocean-going vessels and is a popular fishing ground, as well as a popular boating and windsurfing river.
The County offers the only two marine parks in Oregon: Sand Island on the Columbia River and J.J. Collins Memorial Marine Park on the Multnomah Channel. This is known locally as Coon Island.
(Source: ColumbiaCounty.or.us)
According to the U.S. Census Bureau, the county has a total area of 688 square miles (1,781.9 km2), of which 657 square miles (1,701.6 km2) is land and 32 square miles (82.9 km2) (4.59%) is water. The vast majority of this is in managed coast range forest with limited accessibility.
Habitats of Columbia County
There are three EPA Level IV designated ecoregions in the county:
Level IV: (1d) Coast Range Volcanics
The Volcanics ecoregion consists of steeply sloping mountains and capes underlain by fractured basaltic rocks. Elevation generally varies from 600 to 4100 feet (180 to 1250 m), although in some places the volcanic rock extends down to sea level. The region is marked by columnar and pillow basalt outcrops. Its mountains may have been offshore seamounts engulfed by continental sediments about 200 million years ago. High gradient, cascading streams and rivers occur, and the basaltic substrate preserves summer flows that are more consistent than streams on the sedimentary rocks in surrounding ecoregions.
The streams still support runs of spring Chinook salmon and summer steelhead. The region’s Douglas-fir plantations are heavily logged. Mature forests consist of Douglas-fir, western hemlock, salal, sword fern, vine maple, Oregon grape, and rhododendron. Wetter slopes and riparian areas may support western red cedar, big leaf maple, red alder, salmonberry, and oxalis. Grassy coastal headlands and mountaintop balds feature Roemer’s fescue, thin bentgrass, California oatgrass, and diverse forbs.
Level IV: (1f) Willapa Hills
The Willapa Hills ecoregion (named for the Willapa Hills) consists of low, rolling hills and low, gently sloping mountains with medium gradient streams and rivers. It rises to an elevation of approximately 1,300 feet (396 m).
This region has a lower drainage density than other upland areas in the Coast Range. Logging is relatively easy and less expensive in this accessible terrain, and industrial timberland has almost completely replaced the historic forests. When disturbed, the silt- and clay-textured soils are easily eroded, thereby degrading stream quality.
The vegetation consists of Douglas-fir and western hemlock forests, with sword fern, vine maple, salal, Oregon grape, and rhododendron shrub layer. Wetter slopes and riparian areas support red alder, western red cedar, big leaf maple, salmonberry, and oxalis. Large herds of Roosevelt elk winter in the region.
Level IV: (3a) Portland/Vancouver Basin
The Portland/Vancouver Basin ecoregion (named for the cities of Portland and Vancouver) is a geological depression at the base of the Portland Hills fault-block. The region covers 305 square miles (790 km2) in Washington and 269 square miles (697 km2) in Oregon, including the northern and eastern suburbs of the Portland metropolitan area. It contains the confluence of the Willamette and Columbia Rivers and is composed of deltaic sands and gravels deposited by Pleistocene floods, notably the Missoula Floods. Elevation varies from 0 to 300 feet (0 to 90 m), with buttes as high as 650 feet (200 m).
Historically, the basin was characterized by Oregon white oak groves and Douglas-fir forests on the uplands; black cottonwood groves on riverbanks and islands; Oregon ash, red alder, and western red cedar in riparian areas; and prairie openings maintained by Native American burning, with camas, sedges, tufted hairgrass, fescue, and California oatgrass. Numerous wetlands, oxbow lakes, and ponds can still be found, but today the region is dominated by urban and suburban development, pastures, cropland, and tree farms.
The climate is usually marine-influenced, but easterly winds from the Columbia River Gorge periodically bring continental temperature extremes. It contains several National Wildlife Refuges within the Ridgefield National Wildlife Refuge Complex.[2][3]
——————————————————————————————
That’s the big picture. From a birder’s perspective there are basically four major habitats: 1) the Columbia River, 2) lowland basins bordering the river, 3) the hills of the Coast Range and 4) urban and rural residential areas.
The Columbia River is essentially monotypic, but not quite. There are numerous islands, sheltered coves and inlets that break up the flow, offer some measure of protection and vary the habitat a bit. It is on the Columbia where the best chances of finding divers and stray gulls will be found.
The lowland basins bordering the Columbia offer the largest diversity of habitat, and on Sauvie Island the only terrestrially accessible area managed for wildlife. There are three separate basins along the Columbia. The first is the Portland/Vancouver basin which goes as far north as St. Helens and south to the southern border of the County on Sauvie Island. The second is the Rainier Basin which is an alluvial plain of the Columbia piled up against rapidly ascending Willapa Hills. And third is the Clatskanie basin including the Marshland Drainage District which is a large pocket of lowland around the Clatskanie River and is flood controlled by a series of dikes. One could arguably call the Trojan lowlands a fourth. It is within these lowlands, bordering the Columbia, that the greatest diversity of birds will be found in the County.
The hills of the Coast Range, while not completely monotypic, it’s darn close. The Nehalem River and it’s tributaries cuts a riparian zone through the hills, there are a few agricultural stretches on suitable land, mostly lying along major creeks like Milton Creek, and a few lakes here and there. But the vast majority of this land is held privately and is managed for timber. There are numerous gravel roads throughout and most timber lands allow walk-in access. It is in the hills where the elevational birds like grouse, Hermit Warblers, and Red Crossbills will be most easily found.
The urban and rural residential areas are not specifically covered in this guide, aside from a few parks. But the towns of Scappoose, St. Helens, Columbia City, Rainier, and Clatskanie all have potential to be additive to a day in the field.
