V O L U M E 6 9 ( 2 0 1 5 ) • N U M B E R 1 151 N O R T H E R N C A L I F O R N I A 14 Nov (ph. D. Flaim). Brown Thrashers were on F.I. 29-30 Sep and 13-14 Oct (both Point Blue), and another was at Point Richmond, Al - ameda 13 Oct (R. A. Bok). Seven Red-throated Pipits (all coastal) furnished a typical fall total. All 47 Lapland Longspurs were in coastal coun - ties. Chestnut-collared Longspurs were at Lake Tolowa, Del Norte 17 Oct (LBr), at the Presidio, S.F. 3 Nov (PSar), and on Bear River Ridge, Hum - boldt 2-25 Nov (RbF, m.ob.). Four Snow Bun- tings provided our highest total since 1999 and included 2 on Bear River Ridge, Humboldt 2-17 Nov (Brad Elvert, Bob Brown, m.ob.) and singles at Tennessee Valley Nursery, Marin 18 Nov (Jim Caldwell) and Modoc N.W.R., Modoc 17-19 Nov (ph. Dominic Backman). With the exception of a Grace's Warbler at Pacifc Grove, Monterey 6 Sep (eighth for the Region; ph. DR, CSc et al.), this season was gen - erally lacking in warbler highlights. However, most of our regular vagrants were present in good numbers. Ten Ovenbirds and 41 Northern Waterthrushes were totals more than twice our long-term averages. Twenty-six Black-and-white Warblers and 47 Tennessees also represented above-average numbers. Pronthonotary War - blers were in Golden Gate Park, S.F. 30 Sep–10 Oct (Russ Bright, m.ob.) and at Point Arena, Mendocino 20 Nov (ph. Leslie Dalhoff), and our only Lucy's Warbler was at the Big Sur River mouth, Monterey 19 Oct (ph. MiR, ph. AHo). A Nashville Warbler at McKinleyville, Humboldt 20-21 Nov (RbF) showed behavior traits (lack of tail-pumping) and plumage characteristics consistent with the e. subspecies. Three Virgin - ia's Warblers were in Monterey, one each in El Carmelo Cemetery 21-24 Sep (BTM, ph. CRo, m.ob.), near Esplanade Park in Pacifc Grove 28 Sep (Beko Binder, LRo, m.ob.), and in Mis - sion Trails Park 10 Oct (CSc). Another Virginia's Warbler was at Antonelli Pond, Santa Cruz 7-9 Oct (JGa, Jack Mazza, m.ob.). The majority of California's Connecticut Warbler records are from F.I., so a bird banded there 20 Sep (ph. Point Blue) was not unexpected. Second only to F.I., P.R.N.S. accounts for over one-tenth of our records for this species, and the bird photo - graphed there 28 Sep (ph. CCo, m.ob.) provided the thirteenth record for that location. F.I. also produced our only Mourning Warbler 10-12 Sep (Point Blue). Humboldt provided both our Hooded Warblers, one at the Sequoia Park Zoo 28 Aug (Camden Bruner) and the other at Bay - side 8 Oct (JCP, m.ob.). American Redstarts were present in good numbers (58 vs. an average of 48) with a bird at Chester, Plumas 7-11 Nov (RDB, CPD) being notable in this location for the late date. There were at least 2 Cape May Warblers at P.R.N.S.: one or more 6 Sep (ESH, Durell Kapan) and an - other bird 19-21 Sep (Michael Park, Zach Baer, Sullivan, ph. m.ob.), remained through 6 Dec, providing the second Dec record for San Mateo. Sacramento's frst Yellow-throated Vireo and the third for the C.V. was at C.R.P. 20-21 Sep (†JTr, Michael Gertz, CCo, JCS, GEw, LMcC). Two Plumbeous Vireos were reported: one along Tunitas Creek Rd., San Mateo 1 Sep (†GrH) and another at F.I. 20 Sep (ph. JTz et al.). The lat - ter established the third record for the island. Our only Blue-headed Vireo, at Bethany Curve Park 29 Sep (ph. AMR), provided the second record for Santa Cruz. A Warbling Vireo at Ar - cata, Humboldt 31 Oct (TMcK) and another s. of Corcoran, Kings 9 Nov (ph. MSy) were about a month late. Five Philadelphia Vireos were all coastal except one—an imm. at Lodi 19-20 Sep (†DGY, m.ob.), the frst record not only for San Joaquin but apparently the entire C.V. Six Red- eyed Vireos included Plumas's frst at Chester 8 Sep (†RDB). Among 5 Yellow-green Vireos re - ported was Sonoma's frst, at Owl Canyon 10-11 Oct (ph. Gordon Beebe, m.ob.). Like Lewis's and Acorn Woodpeckers, Steller's Jays appeared in unusually large numbers in the Coast Range and popped up in the C.V., where they are usually absent. Large focks, including one with about 150 birds at Brazos Bridge, Napa 23 Oct (MBe), formed from Mendocino to Napa, and smaller numbers moved through the Sacra - mento Valley from Shasta to Sacramento. Hum- boldt has hosted more Blue Jays than any other county in the state; its seventh was at Willow Creek 1-9 Nov (Mark Hodgson, ph. m.ob.). A total of 8 Townsend's Solitaires away from ar - eas of residency was about typical. Huge pulses of American Robins, including a high count of 12,500 over Point Pinos, Monterey 17 Nov (BLS), and Varied Thrushes, including a high count of 7120 over Skyline Memorial Park, San Mateo 27 Oct (RSTh), pushed through some coastal areas; smaller numbers appeared throughout most of the Region. The appearance of mainly gray- backed female Varied Thrushes led one observer (JM) to suggest the invasion may have involved mainly the more northerly and interior subspe - cies I. n. meruloides. THRASHERS THROUGH WARBLERS Five Gray Catbirds, more than twice our sea- sonal average, included singles in Owl Canyon, Sonoma 28 Aug–13 Sep (PBC et al.), at McKin - leyville, Humboldt 26 Aug (TMcK, ph. SBT), at P.R.N.S. 2 Oct (Nick Whelan, Daniel George), at Carmel River S.B., Monterey 25 Oct (MKu), and at Laguna Grande, Monterey 28 Oct (CHz). A Sage Thrasher at n. Lake Tahoe, Placer 4 Sep (DRs, SRs, JLD) represented the third modern Placer record. Other notable Sage Thrashers were on Latrobe Rd., Sacramento 22 Sep (Deb Watson, ph. LPt et al.), s. of Corcoran, Kings 10 Nov (MSy), and at MacKerricher S.P., Mendocino 15 Red-naped Sapsuckers, 10 coastal and 5 in - land, nearly doubled the 10-year average. Both early Merlins were found in Humboldt, at Arcata Marsh 6 Aug (AxL, Samantha Bacon) and at n. Humboldt Bay 26 Aug (DFx). Presumably all related to a single imm. bird, reports of a Crest - ed Caracara came from three locations around Monterey: w. of Greenfeld 6 Aug (Mike Tidwell), along Elkhorn Slough 4 Sep (Peter J. Dunn et al.), and at Andrew Molera S.P. 20 Sep–13 Dec (CSc, ph. DR, ph. Michael Park, m.ob.). F.I. has produced most of the Region's ac - cepted records of Yellow-bellied Flycatcher; it turned up another 10 Sep (ph. DJM, AdS, Oli - ver James). A total of 14 Least Flycatchers, 8 of which were on F.I., included the frst for Kings at Corcoran 20 Oct (ph. MSy). Four Eastern Phoe - bes included singles at Corcoran, Kings 25-26 Oct (ph. MSy); Bodega Dunes Campground, So - noma 1 Nov (DFr); Pescadero, San Mateo 14 Nov (a bird returning for its fourth consecutive win - ter; RSTh); and Los Banos, Merced 17 Nov (ph. JHr, RBk). All 3 Vermilion Flycatchers reported were in the vicinity of Los Banos, Merced, with a male at Santa Fe Grade Rd. and Wilson Rd. 3-31 Nov (JHr, RBk), a female at Merced N.W.R. 18- 31 Nov (Laurie Dan, ph. George Folsom), and another female on lower Santa Fe Grade Rd. 19 Nov (ph. KVV). The season's only Dusky-capped Flycatcher was nicely photographed at P.R.N.S., Marin 2 Nov (ph. Bob & Bettina Arrigoni). Es - tablishing one of our highest fall totals ever, a minimum of 63 Tropical Kingbirds were report - ed from eight coastal or S.F. Bay counties, with an impressive 21 in Humboldt and a high single- location count of 7 at the Big Sur River mouth, Monterey 12 Oct, when 4 were photographed to - gether (ph. MiR). Five Eastern Kingbirds includ- ed one inland at Truckee, Nevada 27 Aug (ph. RCD, Dale Rubach). Our only Scissor-tailed Fly - catcher, found in Half Moon Bay 25 Nov (Tim Humboldt County has tallied more records of Blue Jay than any other county is California; this bird at Willow Creek 1-9 (here 4) November 2014 established Humboldt County's seventh record.
