Sun Mountain 50K 2012
2012-05-20 10:00 for 6 hrs 50 mins (marathon) 60 sightings Methow Valley (WAOKMETV) Winthrop, WA (USA) Lat,Long: 48.46394,-120.25682 Map Elevation: 2000 feet
The Methow River drains the east side of the North Cascades from Lake Chelan to the Canadian border. Habitats include a ribbon of cottonwods along the river, pastures and residences in the valley, meadows with varying mixtures of bitterbrush, sagebrush and serviceberry on the lower hillsides with scattered groves of aspen, ponderosa pine forest and mixed coniferous forest. Mostly overcast, low 60's, light breeze. Several different loops on XC ski and hiking trails in the area of Patterson Lake about 3 miles WSW of the town of Winthrop. To see a map, browse to http://www.mybirdnotes.com/images/SunMountain50K2012.jpg. From the Chickadee trailhead we ran S along the lake then up Rader Creek and S to the head of the Thompson Creek drainage, then back down Rader Creek and NW past Gobbler's Knob, around and over the ridge topped by Sun Mountain Lodge, then back to Patterson Lake and up and down the NW slope of Patterson Ridge. Route was probably 50% mixed coniferous forest, 30% shrub-steppe, 15% riparian woodland and 5% water, hay fields and residential.
I carried binoculars and recorded species and counts during the run though I only counted for the first half, estimating counts for the remainder of the race. In the second half bird activity diminished somewhat though I added a dozen or more species. I identified most individuals by song. Counts are probably incomplete for many species, especially the common ones, and I didn't try to identify small birds flying overhead.
Canada Goose 20   Marshy SE end of Patterson Lake
Mallard 3   Patterson Lake
Dusky Grouse 2   One seen, another heard, displaying in pine-fir grove on Peterson Ridge. The bird I saw had dull (somewhat orangish) red air sacs, orange eye crests and a gray outline of a terminal band on the tail. Though the bird was on the ground the "voop" sound, deep and soft, seemed to be coming from 5-15 feet overhead.

Spotted Sandpiper 1   Patterson Lake

Hammond's Flycatcher 12   Riparian and mixed coniferous forest. ID'd by songs with first phrase an emphatic two-syllable "sieeee-prrt", the second syllable much lower-pitched than the first.
Dusky Flycatcher 4   ID'd by first phrase of song "sieelip", the second note similar in pitch to the first. Open dry coniferous woods, mostly pine.

American Robin 5   Several singing
Orange-crowned Warbler 2   Singing in riparian and low mixed second growth
Nashville Warbler 10   Most identified by song, but some songs were probably mis-identified Yellow-rumps. In brushy areas near trees. Two-part trill, the second part faster than the first: "chiwee-chiwee-chiwee-chiwee-chiwee-tritritritritri"
MacGillivray's Warbler 2   Singing in thickets along or near streams. Rapid "churri churri churri churri chree chree" or something similar.
Yellow Warbler 8   Singing in mostly in aspen, cottonwood and willow
Yellow-rumped Warbler 15   Many singing. I called several different songs yellow-rumped including the soft warbling trill and various two-part musical trills in which the second part is shorter than the first. Some song variants are hard to distinguish from MacGillivray's and Nashville warbler songs.
Townsend's Warbler 15   Coniferous woods. Songs typically something like "sieeeei-sieeeei-treek-treek", not very buzzy. One bird foraging in riparian D Fir but not identified, was singing a more buzzy "zee-zee-zieeeee-zheezik", the third syllable ascending and drawn out.
Wilson's Warbler 1   Singing, riparian?
Western Tanager 15   Singing in woods
Spotted Towhee 10   Brushy areas near trees
