N O R T H A M E R I C A N B I R D S 166 C E N T R A L A M E R I C A well out of range, having been previously un- recorded both s. of the pine savannas in s.-cen. Belize and w. of the pine savannas in e. Hondu - ras; San Pedro Sula lies between these two dis- junct populations. A Tropical Kingbird on tiny Lime Caye 27 Oct (ph. LJ), the southernmost cay in Belize, was the frst to be recorded on any of the smaller Belize cayes. It is resident on a few larger cayes in n. Belize. Also in Belize, an early fall Eastern Kingbird was seen 21 Jul at Corozal Town (NW), and a seldom reported Gray Kingbird was at Cattle Landing 28 Oct (VB). A rare migrant in Panama, a Scissor-tailed Flycatcher was seen at Punta Chamé 27 Nov (AR). A White-winged Becard at the Lamanai Archaeological Site 4 Oct (JER) provided one of the northernmost records for the species, which has been steadily expanding its range northward since it was frst recorded in Belize in 1970. Not often reported from Honduras, a female Gray-collared Becard was seen briefy but well at Santa Barbara N.P., Santa Barbara 31 ing lot of a supermarket in Tegucigalpa at the end of the day 6 Nov (ph. GFW). It was still present later in the evening, but was gone the next morning. WOODPECKERS THROUGH SWALLOWS Well outside its normal range, a Ladder-backed Woodpecker was seen 2 Nov near San José on the n. shore of Lake Petén Itzá, Petén (CE), where one had been photographed 20 Apr 2014 (ph. CE). These observations add to the species' known range in nw. Petén. Outside its restricted range in Petén, a juv. Orange-breasted Falcon was found 22 Nov in San Benito (ph. CE). Found in Panama only in westernmost Chiriquí where it is rare, a Yellow-bellied Tyran - nulet was seen 19 Nov at Macho de Monte, near Cuesta de Piedra, Chiriquí (VW, MK, RB). An interesting tyrannulet showing some charac - teristics of Yellow-bellied and some consistent with Northern Beardless-Tyrannulet was pho - tographed at Rastrojón archaeological site in Copán 13 Oct (WA, ph. OK). A hybrid, while seemingly unlikely between these two genera, may be the best explanation. A pair of Yel - low Tyrannulets at Marañones, municipality Dulce Nombre de Culmí, Olancho 23 Nov (ph. MMa) provided the frst record of this species in Honduras. Adapted to disturbed habitat, it has probably beneftted from widespread habitat destruction in s. Central America and may be expanding northward. A Belted Flycatcher near Pantin, Baja Vera - paz 6 Sep (JPC) and 9 Nov (JPC, KVV, LB) con- frmed the species' continued presence at this historic site in Guatemala. A female or imm. male Vermilion Flycatcher observed 10 Oct at La Lima near San Pedro Sula, Cortés (CAr) was JvD), a frst for the lake area, was surprising. Rare in Belize, and restricted to the s., a Black- crested Coquette was seen 3 Aug at Cockscomb Basin W.S. (RM), providing one of the few re - cords for Stann Creek. Seldom seen in Panama, a Humboldt's Sapphire was seen 19 Aug at Ja - qué, Darién (ph. EC). Like certain other frugi- vores, Resplendent Quetzal occasionally shows up away from the cloud forests they inhabit in Central America, presumably in response to fuctuating availability of fruits in these forests. An exquisite ad. male seemed quite lost when it was found perched on a powerline in the park - This Pink-footed Shearwater, one of three seen during a pelagic trip of Punta Mala on 25 October 2014, provided the frst photographic documentation of the species for Panamanian waters. At least one was seen in the same area on 22 November 2014. Photograph by Rafael Luck. Honduras's frst Wedge-rumped Storm-Petrel was this bird, noted about 3 kilometers south of Amapala Island in the Gulf of Fonseca 3 August 2014. The photograph shows a relatively long tail projection past the white uppertail coverts, sug - gestive of the subspecies Oceanodroma tethys kelsalli. Photograph by Mayron Mejía. On the 3 August 2014 expedition of Amapala Island in the Gulf of Fonseca, at least 6 Black Storm-Petrels were observed, including the one shown here. Collectively, these birds provided the frst record for Honduras, although the species was not unexpected. Photograph by Mayron Mejía. Guatemala became the last Central American country to record Southern Lapwing when this individual appeared 12- 13 (here 12) August 2014 at Rubelsanto in northwestern Alta Verapaz.

SA A one-day record for the largest number of raptors migrating past the Cerro Ancón Raptor Watch site in Panama City was set on 2 Nov with an extraordinary 2.1 million raptors counted, including more than 1.4 million Turkey Vultures, 495,000 Swainson's Hawks, and 135,000 Broad-winged Hawks (AA, OJ, JPe, JPR). Belize, however, at the base of the Yu - catan Peninsula, is of the beaten track for migrating North American raptors, with relatively small numbers of Mississippi Kites and Broad-winged Hawks, only a few Swainson's Hawks, and no documented migrant Turkey Vultures passing through the s. part of the country each fall. But the mystery of large numbers of Hook-billed Kites migrating past coastal s. Belize each fall continues. An impressive 5,086 were recorded by the BRRI team passing Cattle Land - ing between 10 Oct and 15 Dec (RP, VB, AF, AL, IM, etc.), the last survey day of the fall, on their annual trek to and from points yet unknown. Hook-billed Kite is presumed to be resident wherever it occurs, and this presumption is supported by a now substantial base of records in eBird. However, this is a secretive forest-dwelling species with only a small fraction of its true numbers ever detected—except when migrating. With upwards of 5000 birds migrating south past just one observation point each fall, could such large numbers represent such a small fraction of the total population, that no seasonal reduction in numbers would be no - ticed anywhere within its range n. of Belize? Another tropical raptor species recently thought to be strictly resident, migrating Double-toothed Kites were documented for the frst time in Belize, with 74 recorded moving south past Cattle Landing between 10 Nov and 15 Dec.
