V O L U M E 6 9 ( 2 0 1 5 ) • N U M B E R 1 155 S O U T H E R N C A L I F O R N I A not so much for being the frst for the Chan- nel Islands but for the unprecedented early fall date. A species averaging about one record every other fall in the Region, a Great Crested Flycatcher was at Refugio S.B., Santa Barbara 4 Oct (DMC). An expected push of some 35 Tropical Kingbirds on the coastal slope after 20 Sep included a few that remained to winter; outliers were an early bird at Point Loma 23 Aug (GN) and one at N.E.S.S. 2 Dec (RMcK). Eastern Kingbirds, all in San Diego, were on Point Loma 6 (SBM) & 13 Sep (PG) and at San Diego 22-25 Sep (SBM, CA). A Thick-billed Kingbird at San Dimas, Los Angeles 15 Nov+ (TM) had returned for its second winter there. VIREOS THROUGH LONGSPURS A late migrant Bell's Vireo at G.H.P. 8 Oct (SLS) was eclipsed by an exceptional bird at Bishop, Inyo 28 Nov (DV); a bright nominate bird was on San Clemente Island 10-17 Nov (JTS). The only Yellow-throated Vireo was at Encinitas, San Diego 28 Nov (TDr). Thirty-one Plumbeous Vireos on the coastal slope after 21 Sep included the frst for Santa Catalina Island 26 Sep (KLG, SJS); 2 were on the e. Kern deserts 20 Sep–4 Oct, and another was at Thousand Palms, Riverside 28 Nov (NW). Philadelphia Vireos were at Goleta, Santa Bar - bara 25 Sep (WTF) and Camarillo, Ventura 12 Oct (JMu). Once again, Red-eyed Vireos—with singles at Big Pine, Inyo 24 Sep (T&JH) and Morro Bay 30 Oct (KLP)—were outnumbered by Yellow-green Vireos. Six of the latter spe - cies were found: on Point Loma 9-10 Sep (JoB, CAM), at San Diego 20-22 Sep (EA, SBM), on Point Loma again 11-17 Oct (DoM, DA), at Carpinteria 2-7 Oct (FS), near Port Hueneme, Ventura 9 Oct (FD), and at Lakewood, Los An - geles 30 Oct (JBy). Scarce as a fall migrant, a Purple Martin was at S.C.R.E. 20 Sep (LSc). Eighty Bank Swal - lows at S.E.S.S. 13 Aug (GMcC) must be the highest count of migrants anywhere in the Region in many decades. The Black-billed/Eur - asian Magpie on Santa Rosa Island remained (from 15 Jun) through at least 11 Nov (JBt); vocalizations were thought to be consistent with Black-billed. A Clark's Nutcracker at East Cuesta Ridge 3 Nov (CJ) was the frst for San Luis Obispo in 14 years. Three Chestnut-backed Chickadees at Carpinteria 11 Sep (PAG) were at the s. extreme of the species' expanding range. No signifcant fight of Red-breasted Nuthatches occurred in the lowlands during the period, though individuals did wander as far as San Clemente Island 24 Oct (CLT) and S.E.S.S. 2 Oct (CC). Wandering Brown Creep - ers included the frst for Carrizo Plain N.M., San Luis Obispo 11 Nov (KMS) and the third for San Clemente Island 16 Nov (BSS). A Pacifc Sep (PR) and later collided with a window in La Mesa, San Diego 2 Dec (Project Wildlife), providing only the third record for California; the rehabilitated bird was transported back to Portal and released. A most cooperative ad. male Ruby-throated Hummingbird that fre - quented a feeder in Arroyo Grande, San Luis Obispo 3-6 Sep (BKS) provided only the fourth record for the Region. A minor fight of Lewis's Woodpeckers re - sulted in single birds found at such locations as Hart Park in Bakersfeld, Kern 1-7 Nov (K&BK), Zzyzx in the San Bernardino desert 23 Sep (BD), Desert Center 14 Oct (CMcG), Imperial Dam, Imperial 17-18 Oct (DVanP), and near Mount Signal, Imperial 9 Nov (GMcC). Acorn Woodpeckers wandered wide - ly throughout the Region, with some reaching the coast at Los Osos and Oceano in San Luis Obispo and at Huntington Beach, Orange after mid-Aug, and others appearing on Point Loma and at Mission Bay in San Diego after mid-Sep, along with at least 3 off the coast on San Cle - mente Island after 10 Sep (JTS); in addition, others were found at such unlikely places as Rovana, Inyo 19 Sep (JLD) and at remote desert oasis such as at Crystal Spring, San Bernardino 1 Nov (TAB). Single Williamson's Sapsuckers at Holiday Lake in the w. Antelope Valley, Los Angeles 25 Nov (CDY) and at Desert Center 23 Oct (ph. BSa) were at unexpected locations. At least 9 Yellow-bellied Sapsuckers were found at various locations scattered throughout the Region after 5 Oct. Reports of a Crested Caracara at N.E.S.S (North Shore) 9 Nov (DRa), S.E.S.S. (Rock Hill) 25-26 Nov (ES, TAB), and near Signal Mountain 9 Dec (ChB) may have pertained to a single bird moving southward through the Salton Sink. One that arrived on the Channel Islands in Apr and settled on Santa Catalina Is - land was still present 18 Oct (TDv). An Olive-sided Flycatcher at Niland 23 Aug (GMcC) was the earliest ever in fall in the Salton Sink. In contrast, a Willow Flycatcher at Brawley 13 Oct (GMcC) established the lat - est fall date for the Sink. The only Least Fly- catchers were at Manhattan Beach, Los Ange- les18 Sep (JSF), Avalon, Santa Catalina Island 26 Sep (KLG), and Point Loma 20 Sep (GN). An apparently wintering Dusky Flycatcher was at e. Anaheim, Orange 25 Nov+ (MH). Eastern Phoebes were at Torrance, Los Angeles 6-9 Nov (MD) and on the deserts at Baker, San Bernardi - no 26 Oct (DMG) and Bard, Imperial 7 Nov (PEL). A male and 2 juv. Vermilion Flycatchers at Lone Pine, Inyo 20 Aug (RDK) proved local nesting at a site where the male has been seen since Apr. A Dusky-capped Flycatcher on San Clemente Island 20 Aug (JTS, BSS, STM), if en - dorsed by the C.B.R.C., would be astonishing Luis Obispo 12 Oct (TDS), La Jolla 4 Aug (PEL), and Oceanside 12 Sep (JCo), but one ventured high into the San Bernardino Mountains to Big Bear Lake 9 Nov–15 Dec (ET). Away from the Salton Sea, where single Heermann's Gulls were found at S.E.S.S. 3 Aug–1 Sep (BoM, GMcC) and 1 Oct (GMcC) and at N.E.S.S. 18 Nov (RMcK), one was at the Prado R.P., San Bernardino 11 Nov (CAM). A Mew Gull at the Prado R.P., San Bernardino 9 Nov–13 Feb (TAB) and another at Desert Center 16 Nov (RDW) were both well inland, where very rare. At least 6 Lesser Black-backed Gulls at the S.J.W.A. and on the Salton Sea after 21 Sep (AEM, RDW, GMcC) was about average. The only Glaucous Gull reported was a hatch-year bird at N.E.S.S. 18 Nov (RMcK). A Gull-billed Tern at S.E.S.S. 1 Oct (GMcC) was the latest this year. An im - pressive 3000 Black Terns at Salton City, Im- perial 5 Sep (CMcG) marked the peak of the fall migration for this species. An Arctic Tern at Tinemaha Reservoir, Inyo 12 Oct (SLS) was far inland, where very rare. PIGEONS THROUGH FLYCATCHERS Band-tailed Pigeons were clearly on the move, with large numbers reported from mountain locations and strays being found on the imme - diate coast such as on Point Loma 10 Oct (ShF) and Mission Bay 21 Oct (PEL) and at remote locations in the e. part of the Region such as Crystal Spring, Inyo 9 Oct (JEP) and along the Colorado River at Bard, Imperial 26 Oct (PEL). Inca Doves appear to be increasing around Bor - rego Springs, San Diego after being found there in Dec 2013, with 3-4 at two widely separated locations at the end of the period, this now be - ing at the extreme w. edge of this species' range in California. Single Common Ground-Doves at Lake Woollomes 15 Aug (SDS) and near McFarland 8 Sep (SDS) were at the n. extreme of the species' expanding range in Kern. More than 55 White-winged Doves along the coast and on San Clemente Island between 8 Aug and 13 Nov was certainly more than expected. A Spotted Owl in Cottonwood Canyon near the 210 Freeway in Pasadena, Los Ange - les 5 Oct (MCL) was unexpected, as was also a Northern Saw-whet Owl at El Dorado Park, Long Beach 30 Oct (JeB). Two Black Swifts over Santa Barbara 18 Sep (MLS) and 4 more over Carpinteria 9 Sep (MV) were in an area where small numbers are expected in fall, but one over Point Loma 8 Sep (GN) provides one of a very few records of a fall migrant in San Diego. Up to 5 Chimney Swifts were present over Elysian Park in downtown Los Angeles 1-10 Sep (CAM, MS). A male Blue-throated Hummingbird, banded near Portal, AZ 14 Jul 2013, attended a feeder in the town of Lake Gregory in the San Bernardino Mountains 18
