OREGON & WASHINGTON 
tie, T. Mansfield, M. E Mathis) were w. of the 
Cascades, where not annual. Nine apparent 
arcticola Horned Larks dropped in at Marys 
Peak 22 Sep (WDR); though this taxon is 
known to migrate through the Region, most w. 
Oregon encounters involve the rare locally 
breeding Streaked Horned Larks (subspecies 
strigata). An impressive 200 Purple Martins 
joined the Yamhill Barn Swallow roost 11 Sep 
(M. Hamm); this count is likely attributable to 
the growing number of nesting pairs in the Re- 
gion — now about 1400 — and in neighboring 
British Columbia, which had only 10 pairs in 
1980 and now has 600 -h. A Bank Swallow at 
Ankeny 26 Sep (RG) was at least a month 
tardy for the W.Y, where the modest fall pas- 
sage typically occurs during mid-Aug; 
“dozens” at Sauvie 1. 11 Aug QG) were likely 
local breeders dispersing from a new colony 
just to the n. at Prescott, Columbia. A Petivche- 
ticlon swallow at Samish Flats, Skagit 10 Nov 
was not identified to species (MB); consider- 
ing that Cave Swallows often appear on the 
Atlantic Coast in Nov, and this seasons “inva- 
sion” of species from the American Southwest, 
this bird should not be assumed to have been 
a Cliff. If indeed a Cliff Swallow, it was about 
five weeks late. The massive fall Barn Swallow 
roost near Dayton, Yamhill (active since the 
mid-1980s) held up to 550,000 birds during 
mid-Sep (D. Albright, E Schrock). A group of 
6 Barns at Othello 13 Nov (RH) was about a 
month late for the eastside. 
Though Black-capped Chickadee x Moun- 
tain Chickadee hybrids have been document- 
ed elsewhere, one at Spring Canyon C.G., Lin- 
coln 25 Oct (ph. RS) was apparently Wash- 
ington’s first. A mini-invasion of Mountain 
Chickadees into lowlands was mostly con- 
fined to w. Washington, where 25 were de- 
tected 28 Sep+; w. Oregon had just three low- 
land reports. Unlike the 2004 invasion, most 
reports involved singles, and none was re- 
ported w. of Puget Sound. A White-breasted 
Nuthatch enlivened Snolqualmie, King 30 
Oct-9 Nov (ph. A. Cockman); since the extir- 
pation of the s. Puget Sound population, 
some have speculated that recent reports from 
nw. Washington are tcnuissima wandering 
from e. Washington, rather than the slender- 
billed aculeata, which inhabits sw. Washing- 
ton. However, few have been adequately doc- 
umented. A freshly fledged juv. Rock Wren w. 
of Camas Valley 15 Aug (TR) confirmed 
Coos's first nesting record; an ad. had sung at 
this site throughout the summer. A Bewick’s 
Wren near Colville, Stevens 28 Nov (TL) adds 
to evidence of a northeastward range expan- 
sion. Washington’s 1 1 th Blue-gray Gnatcatch- 
er visited O.S. 13 Sep (tM. Brueninger); most 
Washington records are from late fall or win- 
ter. Another gnatcatcher was at Prineville 29 
Aug (CG); they are now rare but annual in 
Crook. A Blue-gray Gnatcatcher at Fields 22 
Sep (TR) was a rare fall migrant in se. Oregon. 
The tally of 300,000 American Robins count- 
ed during a Crook raptor survey 11 Nov in 
was deemed “conservative” (SD, CG). 
Very rare westside Gray Catbirds were at 
Portland 7 Aug (M. Bryant) and Ridgefield 9 
Aug (BE); e. Oregon’s lone bird, at Bend 4 
Nov (V Threlkeld) was about six weeks tardy. 
Seven Northern Mockingbirds 8 Aug-29 Oct 
represents a typical fall; the lone Washington 
bird visited Seattle 16 Aug (P Rose). A Sage 
Thrasher at Skagit W.M.A. 30 Sep furnished 
just the 3rd w. Washington fall record (H. 
Armstrong, M. S. Dallas). Washington’s 11th 
Brown Thrasher enlivened Sprague L., Lin- 
coln 21 Aug 0 Acton), and the 12th appeared 
at Nisqually 22 Sep (tM. Lee). Oregon’s 4th 
Eastern Yellow Wagtail stopped briefly at 
Seaside 26 Aug OGfi JC. ph- OS); five of the 
Region’s six records have come 29 Jul-8 Sep. 
WARBLERS 
Five Tennessee Warblers 8-21 Sep matched 
recent fall totals. Singles at Washtuena 8 (ph. 
DS) & 21 Sep (teW, SM) and a late bird at 
tbe Elwha R. mouth, Clallam 16 Nov (tSM, 
tBW, teW) add to 20 prior Washington 
records. Though most fall Tennessees appear 
late Aug-mid-Sep, the Region has 10 winter 
records. Supranormal numbers of Orange- 
crowned Warblers lingered to the period’s 
end, evidenced by 5 at tbe Elwha R. mouth 16 
Nov, 8 at Bandon 28 Nov (AC, RHo), and 5 at 
Portland 30 Nov (DM); typically, Nov-i- re- 
ports involve single birds. Single Nashville 
Warblers, not annual during fall in w. Wash- 
ington, appeared at Seattle 22 Aug (M. 
Bartells) and Tokeland, Pacific 28 Sep (G. Mc- 
Cwethy). A brightly colored Nashville War- 
bler at Lyons Ferry 7 Sep did not wag the tail 
and appeared to be potentially of the e. sub- 
species ruficapilla (tSM, tDI); though not 
positively documented in the Region, this 
taxon has been recorded farther s. along the 
Pacific Coast, including a specimen from the 
Los Coronados Is., Baja California (Dunn and 
Garrett 1997; Warblers). Tardy Nashvilles 
were at Coos Bay 15 Nov (TR) and Bandon 28 
Nov (AC, RHo); they are nearly annual on 
Oregon’s westside during winter. A Yellow 
Warbler in Seattle 30 Nov Q. Bragg) was six 
weeks late. Five Chestnut-sided Warblers, not 
annual in fall, included Washington’s first fall 
birds since 2001. Its first coastal bird, at Bot- 
tle Beach, Grays Harbor 1 Aug, was record 
early (ph. RM, tTA, M. Dufort), and singles 
visited Washtuena 8 Sep (tRM et al.) and 21 
Sep (tSM); these added to 16 prior records. 
Oregon’s Chestnut-sideds were at Malheur 16 
Sep (AC) and Hampton, Lake 19 Sep (SD, 
PL). A fall record 4 Magnolia Warblers in- 
cluded Washington’s 15th and 16th at Wash- 
tuena 10 Sep (ph. T. Kenefick) and 21 Sep 
(teW, tSM); Magnolias have been detected in 
Washington four of the past five falls. Singles 
at Corvallis 13 Sep (WDR) and Malheur 30 
Sep (AC) added to about 40 prior Oregon 
records; most of tbe Region’s Magnolias have 
appeared 10 Sep-10 Oct, with a decided spike 
in late Sep. No fewer than 5 Black-throated 
Blue Warblers visited Harney oases 24 Sep-7 
Oct (AC); this species is annual there in fall 
but much rarer elsewhere in the Region. 
A late eastside Townsend’s Warbler tarried 
at Maupin, Wasco 16 Nov (CG). Townsend’s 
Warbler x Hermit Warbler hybrids were well 
e. of the Cascades at Lyons Ferry, Franklin 31 
Aug (SM, CW) and Potholes Res. 27 Sep 
(BW). A migrant Audubon’s Warbler at 
Epbrata, Grant 2 Aug was nearly a month ear- 
ly (SM, CCx). Four Palm Warblers were in- 
land; singles at Davenport, Lincoln 17 Sep Q- 
Acton) and Brothers, Deschutes 21 Sep (TC) 
were very rare for the eastside. Slightly more 
expected westside birds graced Renton, King 
22 Nov+ (K. Andrich) and Peoria, Linn 30 
Nov-r (RC). Seven Blackpoll Warblers, 2 in 
Oregon, 5 in Washington, were at eastside va- 
grant traps 2-21 Sep; Washington has aver- 
aged 3-1- per fall since 2003 and now has about 
33 records, mostly late Aug-mid-Sep. Hood 
River’s first Blackpoll was s. of Hood River 6 
Sep (1. Tomlinson). Four Black-and-white 
Warblers 13 Aug-14 Sep was about average; a 
female along Trout Lake Cr. 30 Aug (tSJ) was 
Klickitat’s first. Three American Redstarts 
were noted in w. Washington, where rare dur- 
ing fall; Skamania’s first was near Home Valley 
20 Aug (SJ). Four redstarts in Harney 17-25 
Sep was a typical fall showing, while one at 
Bend 18-19 Sep (K. Smith, SD) provided a 
rare fall report from cen. Oregon. 
An Ovenbird n. of Washtuena 4 Sep (tBW) 
and another at Leadbetter Pt., Pacific 22 Oct 
(ph. RM) were just the 6th and 7th fall records 
for Washington; most of the Region’s Oven- 
birds are detected May-Jun. Rare westside 
Northern Waterthrushes included one at Asto- 
ria 10 Sep (MP) and up to 2 at Skagit W.M.A 
11 Oct-28 Nov (GB, T. Brooks, N. Turner);^ 
they have been nearly annual at the latter site 
in recent years. Though Northern Wa- 
terthrushes breed in ne. Washington, fall mi- 
grants are seldom seen elsewhere on the east- 
side; therefore 5 in e. Washington 30 Aug-12 
Sep and 4 at Harney oases 12-22 Sep. were un- 
usual. MacGillivray’s Warblers at Malheur 7 
Oct (AC) and Philleo L., Spokane 14 Oct 
(MW) were noted two to three weeks after
