Washington County, Oregon, Big Day: 28 April 2007

  Gray Jay up Scoggins Valley Road 3 miles past Hagg Lake was one of the day's first birds.

It was a tough work week. I needed to go out and see some birds as a catharsis. By Friday it was clear that a couple of hours would not do. I needed to watch birds all day! Thus this was an impromptu Big Day, with no planning or scouting (other than pevious familiarity with the area).

Last year Tim Shelmerdine, Jay Withgott, and I set the county record with 123 species. One of things I remembered was that we "wasted" 2 hours driving to Tualatin Hills Nature Park to pick up a couple of stake-out birds. I thought that the time would be better spent birding, rather than driving out of the way. So I decided to go slower and bird more thoroughly. Owling would end at Hagg Lake, so that's where I would start the day's birding. That should provide all the forest and land birds. Fernhill Wetlands should provide most of the waterbirds. Based on previous attempts, those two locations would provide at least 100 species, and I'd be done by noon. From their I'd try to pick up any species missed by hitting Jackson Bottom Wetlands and Killin Wetlands. The last couple of hours would be spent trying to find any odd species that had eluded me earlier in the day.

Owling started very slowly. By 4:15 am, I had been driving farm roads from Hillsboro to Cherry Grove without encountering an owl. In fact, after and hour and 29 miles, I hadn't heard a single bird of any kind! I picked up several Western Screech-Owls immediately when reaching Hagg Lake. A couple of screeches was all I got from the Northern Saw-whet Owls (they were the only birds calling there in March). By 5:00 am I was up to only 4 species, with and American Robins and Great Horned Owls added to the list. Pitiful.

As dawn spread from the east toward me, the birds song picked up. I headed up into the Coast Range, just 3 miles from the lake. As soon as I got out of the car, I heard Mountain Quail calling. Hairy Woodpeckers and Red-breasted Sapsuckers were tapping out their distinctive drum calls. White-crowned Sparrows were calling from the clear cuts and, well, the game was afoot!

  There were at least 8 Common Loons on Hagg Lake. Though they do not breed here, they yodel their eerie song every spring during migration.

I brought my camera in order to force myself to slow down. The result was that I remained in areas longer and picked up more of the species present than I might normally for a Big Day. I never felt like I was behind schedule, because my planned route was barely 30 miles long, though I would criss-cross it at the end of the day. How different from State Big Days where time and vast distances to travel are the enemy!

I walked up a logging road on the only parcel of Weyerhauser land surrounded by off-limits Stimson Lumber Company holdings. About a half mile up the road I came to the Gray Jay woods and was not disappointed. It was barely light enough to try my camera and play with the exposure compensation settings. A Western Bluebird called, eliminating a stop later in the day. A Sooty Grouse hooted from the woods. At 7:30 am I was back at the car and my list was 46. I drove slowly back 3 miles down to the lake, stopping at several pull-outs. I reached Hagg Lake and drove to the fee booth to buy a day's pass. My species list at 8:00 am was 57.

At this point I determined to bird my way around the whole lake. This involved walking on the trails below Lee Road, Tanner Creek, and the abandoned Recreation Area East, a total of about 4 miles.

The thorough birding of Hagg Lake found most of the birds I had already seen, plus many more. [Big Day tip: ] The birds that I saw only in the hills above Hagg Lake were Sooty Grouse, Mountain Quail, Red-breasted Sapsucker, Hairy Woodpecker, Pacific-slope Flycatcher, Gray Jay, House Wren, Western Bluebird, and Hermit Thrush.

At 11:40 am I finished Hagg Lake, 3-1/2 hours to bird fairly thoroughly around the lake. I had detected 76 total species for the day.

Next I picked up Acorn Woodpecker at Rogers Park in Forest Grove, then hit a drive-thru for lunch, then headed to Fernhill Wetlands.

Water levels were high, so the shorebirds that were here were all in the back vegetation. I saw flocks fly around, so picked up most of the species. I also was still carrying my camera, not my scope, so I risked missing distant ducks or shorebirds.

After 1-1/2 hours I had finished birding Fernhill Wetlands. It was 1:50 pm and my day's list was right on schedule at 104 species.

Next stop was Jackson Bottom Wetlands in Hillsboro. Again, I should have taken my scope to check out the shorebirds up close. Interesting was a thermal of 10 Red-tailed Hawks. A couple of Lincoln Sparrow's flushed from the grassy area in the back woods. On leaving Jackson Bottom it was 3:50 pm and I had 112 species.

At his point I was quite tired and stopped by my house in Hillsboro to rest and refuel with some food and cold drink. The half hour rest did me good, and reinvigorated me for the final chase. I had 112 species; I thought I might reasonably get to 120.

A puddle on Cedar Canyon Road at Hartwick Road contained the first of the day's 4 Solitary Sandpipers #113 and a Wilson's Snipe #114. Killin Wetlands yielded the expected American Bitterns #115 and Virginia Rails #116. It is a good thing that I had heard a Sora at Jackson Bottom because none called while I was here. A mile up Killin road at Narup Road were 3 more Solitary Sandpipers.

The American Dipper #117 just up the road at the Highway 6/8 interchange was under the bridge, on cue. I drove the Old Wilson River Highway and checked the tree farms and filbert orchards, but finally heard a Chipping Sparrow #118 on Stringtown Road in Forest Grove. There were now only five species likely: Blue-winged Teal, Hooded Merganser, California Quail, Vaux's Swift, and Cliff Swallow. Of course there were a dozen other species possible, including early migratory species such as Warbling Vireo, Western Tanager, Black-headed Grosbeak, and others. But driving through the farmlands and to Fernhill Wetlands and Jackson Bottom again only yielded one new species: Cliff Swallow #119. And that was the end of the day. 3:00 am to 8:00 pm, 145 miles of driving, 7 miles walking, and 119 species, tied for the second highest county listing record. Hmm... I bet by next weekend there'll be a dozen more species moved in, with none lost. With a little help and good weather there's a new county Big Day record waiting... is 130 possible?
