V O L U M E 6 9 ( 2 0 1 6 ) • N U M B E R S 3 / 4 507 C E N T R A L A M E R I C A records were all from winter 2014–2015, one of a remarkable feeding group of 30 individuals. Farther n., several boat trips to the center of the Gulf of Fonseca in s. Honduras in Jun and Jul re - corded several Black Storm-Petrels as follows: 7 on 15 (RG, OD, ph. JvD) and 21 Jun (AA, AF, ph. JvD), and 5 on 29 Jul (RG, OD). All birds were seen several km offshore, and the majority were in active wing molt. The 29 Jul trip also yielded 2 Least Storm-Petrels, a first for Honduras. Both were seen with the much larger Black Storm- Petrels for direct comparison (RG, OD). Three Peruvian Boobies on the Peñón de San José at the Pacific entrance to the Panama Canal, Panamá 19 Jul (ph. MO) and 4 there 25 Jul (VW) illustrated that some stragglers from the incursion that began in Jul 2014 were still present. An American White Pelican seen 17, 21 (RJo), & 22 Jul (ph. MO) at Panamá Viejo in Panama City was first reported in Dec 2014. Also in Panama, an ad. Fasciated Tiger-Heron at Barro Colorado Island in Lake Gatún, Colón 16 Jul (CR) was the first ever recorded at this long-studied locality. Several small groups of 2-3 White Ibis 30 Jun and 1 Jul near Mulatupo, Ustupo, and Isla de Piños (GA) provided the first records from e. Guna Yala. The species is still scarce in this Region, although it is becom - ing more numerous on Panama's Caribbean coast. In Guatemala, a flyover Roseate Spoon - bill at Quirigua 27 Jul (ph. MOv) provided the first summer record for Izabal. A Crested Eagle observed on an expedition to the Río Plátano Biological Reserve in e. Hon - duras was a fantastic find (CF, ph. MaB). This species is seldom reported anywhere in Central America. A Gray-breasted Crake heard at Ama - tique Bay, Izabal 19 Jul (MNo, JPC, OG) estab- lished a new site record. Also in Guatemala, 3 Collared Plovers seen 19 Jul and 2 seen 26 Jul at Santa Elena (ph. CE) furnished the first summer records for Petén. Rare in Panama, a Wandering Tattler was seen 11 Jun (KG) at Fri - joles Rocks near Coiba Island, Veraguas, where it may occur regularly. A summering Parasitic Jaeger was seen multiple times between 2 Apr and 28 Jun on the Pacific side of Honduras at Playa Punta Ratón, Choluteca (ph. JvD et al.), and 2 others, both subads., were seen 21 Jun on the Caribbean coast near La Ceiba, Atlántica (ph. MO'B). A second-cycle California Gull , likely the same individual seen at this location in Jan, Apr, and May, was at Punta Ratón 21 Jun (AA, AF, ph. JvD). Forster's Tern, now annual in Honduras, is still quite uncommon in most of Central America. One was present 27 Jul at the El Jicarito wetlands, Choluteca (ph. JvD), where one was also found almost a year earlier. DOVES THROUGH MUNIAS In Honduras, the march of the Eurasian Col- hill, Edwin Calderón (EdC), Euclides Campos, Liliana Chavarría-Duriaux (Nicaragua), Eva - risto Chocoy (EvC), Enrique Choussy (EnC), Oscar Emmanuel Cisneros, Jan Axel Cubilla, Natalia Decastro, Mark DeHaan, Georges Duri - aux, Francisco Dubon, Carlos Echeverría, Knut Eisermann (Guatemala), Mark Faherty, Ramón Fernández, Chris Fischer, Brian Foster, Daniel Froehlich, Kees Groenendijk, David Hernandez, Cora Herrera, Néstor Herrera, John Hornbuckle, Marshall J.

A bird of aquatic if not marine environments, an American Dipper was new to El Salvador this season. Four Spot-fronted Swifts provided the second record for Panama, and Honduras's second California Gull lingered well into June. DUCKS THROUGH TERNS Seldom seen in the Region in midsummer, a Lesser Scaup was in Honduras at the mouth of the Cangrejal River near La Ceiba, Atlántida 5 Jul (JZ, EL, KB). The great majority of scaup arrive in Nov and leave in Mar or early Apr. A male Crested Bobwhite at Lidice, Panamá Oeste 18 Jun (ph. DA) provided the first record from this lo - cality; there are few records of this species during summer, especially near the e. edge of its range in Panama. A Pink-footed Shearwater seen 18 Jul off sw. Azuero Peninsual, Veraguas (GA, KG, EC, JAC, HL, ph. RL) established only the fourth record for Panama and the second pho - tographically documented. The three previous lared-Dove continues. A pair was seen 3 Jun attending 2 recent fledglings at French Harbor on Roatán Island (OD, ph. RG), confirming the first instance of breeding in Honduras. A Ma - roon-chested Ground-Dove heard near Purul- ha, Baja Verapaz 28 Jul (JPC) established a new site record in Guatemala, while a Gray-chested Dove observed at El Iguanero, Granada 19 Jul (HV) was unexpected on the Pacific slope of Nicaragua. Found in the Caribbean lowlands and foothills, it has been observed on the Pa - cific slope only near the shore of Lake Nicara- gua. Seldom seen in Panama, a Rufous-vented Ground-Cuckoo 12 Jun provided the first re - cord for Donoso, Colón (LV). In Guatemala, a Central American Pygmy-Owl heard 17 Jun at Laguna Lachuá N.P. (LN, MN) was only the second to be reported in Alta Verapaz. A Great Potoo heard near Sayaxche 25 Jun (ABL) provided the first record for Petén. The second department record came a month later when one was seen 27 Jul near Las Pozas (ABL, CE). Rarely reported in Panama, an Oilbird was at a day roost on Barro Colorado Island, Colón 28 Jul (JH). Providing the second record for Panama, 4 Spot-fronted Swifts were found on the Río Chucunaque near Nuevo Vigia de Turquesa, Darién 10 Jul (KE). If these birds are representative of a resident population and not vagrants, their location bridges a major gap between two presumed widely disparate populations, one in Costa Rica and the other in nw. South America. A Striped Woodhaunter was seen and heard singing 3 Jul at Quebrada La Carrizalosa in the Río Plátano Biological Reserve (CF, v.r. MaB). In Honduras, this spe - cies is restricted to the remote e. portion of the country and rarely reported. White-winged Be - card continues to expand its range in n. Central America. One seen near Sayaxche 4 Jul (ABL) was the second to be reported in Petén. On 28 Jul, 2 Cave Swallows were present at Río Jiboa estuary, La Paz (JA, MB, EdC, ph. MT). This species, whose numbers are increas - ing throughout Central America, normally shows up in late Oct. An American Dipper observed 19 Jul at Río Sumpul, Chalatenango (JA, ph. MB, MT) established the latest in a steady series of country firsts for El Salvador. A Slaty Finch seen at Fuentes Georginas 7 Jun (AV) was only the second to be reported in Quetzaltenango, providing one of few records for Guatemala. A pair of Slate-colored Seed - eaters were at the Lubaantun Archaeological Reserve, Toledo 29 Jul (ph. fide EmC). This nomadic species is seldom reported in Belize. Also in Belize, a Tricolored Munia was seen on Caye Caulker for only the second time 8 Jul (DB). Belize's first record of this invasive non- native was also from Caye Caulker twelve years ago. Small isolated populations now appear to
