N O R T H A M E R I C A N B I R D S 560 C e n t r a l a m e r i C a ing the frst Central American breeding record for this species. Another Killdeer was at El Jica- rito 12 Jul (MM, RJ, JvD). Two oversummering birds were reported in s. Honduras last sum- mer, but not at El Jicarito. A Wandering Tattler, a very rare transient in Panama, was on the Frijoles Islets, off Coiba Is- land, Veraguas from 15 Jun+ (KG, ph. FO, PC). Also rare in Panama and not usually recorded before Aug, a Long-billed Curlew was present 19 Jul at Panama Viejo in Panama City (MC). In El Salvador, 25 Marbled Godwits present 20 Jul at Barra de Santiago, Ahuachapán (ECh) was an impressive number for so early in the season, and single Pectoral Sandpipers found 14 Jun (MT, JA, ECa, ph. MBo) and 29 Jun (AM, ph. ECh) at Río Jiboa estuary, La Paz provided the frst eBird records in Jun for the Region. GULLS THROUGH CUCKOOS Unexpected was a Gray Gull seen 19 Jun on the coast s. of Pacora, Panamá (ph. RM, MC, SC, JD). Also seldom reported in Panama, an Inca Tern was seen 4 Jun on Coiba Island (KG). In Costa Rica, where it was recorded for the frst time last winter, one or more Inca Terns were seen at various locations between the Gulf of Nicoya and Drake's Bay through spring, with one reported as late as 7 Jun in San Pedrillo, Corcovado N.P. (DP, NC). Like the Peruvian and Blue-footed Boobies, these birds would have been affected by El Niño in their tradi- tional feeding areas off w. South America. Two Red-billed Pigeons seen in the Bladen 24 km s. of this location on the same day by the same observers. Whistling Heron was report- ed from three widely separated sites in Panama this summer: one about 6 km w. of Chepo, Pan- amá 9 Jul+ (GB, BN, BC, ph. RL et al.); 2 near Gorgona 15 Jul (ph. EC, AG, IR); and one near El Rincón, Herrera 20 Jul (ph. RM, MC, CP, SC, YD et al.). Previously recorded only twice in Panama, in 2010 and in 2013, the bird near Chepo was only 3 km from where the 2013 bird was found and may have been the same returning individual. A Boat-billed Heron seen 29 Jun at Metropolitan Nature Park in Panama City (ph. OQ, RM) was the frst to be reported from this locality. SPOONBILLS THROUGH SANDPIPERS In Guatemala, Roseate Spoonbill is mainly coastal; thus, 3 seen in a wetland 10 km wsw. of Melchor de Mencos, Petén 25 Jul (JM) repre- sented a rare inland report. Most unusual, an Osprey exhibiting plumage characteristics of the ridgwayi subspecies was also at Melchor de Mencos 25 Jul (JM). This subspecies, a Carib- bean endemic, is rare anywhere on mainland Central America. No longer rare in the s. low- lands of Honduras but still rare inland, a Pearl Kite near Salalica, Francisco Morazán was un- expected (ph. JLC). A juv. Gray-bellied Hawk seen 12 Jul near the Río Mono Bridge on the Inter-American Highway, Panamá (ph. EC, AG, IR) was only the second for Panama and one of very few for North America. In Nicaragua, 3 American Avocets seen in El Guayabo wetlands 14 Jun (MB) were either very late migrants or oversummering birds. Southern Lapwing continues its march north- ward through Central America. Two present at El Jicarito 12 Jul (MM, RJ, ph. JvD) were the most recent of several reports from Honduras. Unusual anywhere in Central America during the summer, 2 Killdeer were at El Guayabo wetlands, Granada 14 Jun (ph. MB). But even more remarkable, the same day a pair with a recent hatchling were observed at Península de Chiltepe, Managua (ph. JS), possibly constitut- in fight 19 Jun near Coiba Island, Veraguas (KG) provided only the second record from Panama. Seldom reported from Panama, a Nazca Booby was seen 1 Jul during a boat trip be- tween Coiba Island and Mariato, Veraguas (JB, KB, KG), and another was seen 10 Jul off Punta Mala, Los Santos (JB, KB, GA). Costa Rica wit- nessed an infux of Blue-footed Boobies this summer all along the Pacifc coast, perhaps a result of ENSO-related phenomena. Specifcally, one was offshore from Sirena, Corcovado N.P., Puntarenas 9 Jun (DP, NC); an ad. was perched on rocks off Manuel Antonio, Puntarenas 28 Jun (KH); 2 were seen fying over a ferry in the Gulf of Nicoya, Puntarenas 2 Jul (FR); and 12 were observed in small groups or alone in the Gulf of Nicoya 20 Jul (PO). The latter were seen along the Puntarenas-Paquera ferry route. A Peruvian Booby, a vagrant in Panama, was found 22 Jun in weakened condition on the Amador Cause- way, Panama City (ph. LH). It was taken to Sum- mit Municipal Park, where it died 23 Jun. While the occasional oversummering Ameri- can White Pelican is nothing unusual anywhere on its wintering grounds, a group of 145 on 12 Jul at El Jicarito, Choluteca was unexpected (MM, RJ, JvD). Another 6 individuals were seen This and another Lesser Scaup found 1 June 2014 in the Cangre- jal River estuary in Honduras, along with one found in Costa Rica on the same date, suggest either exceptionally late-lingering individuals or oversummering birds. Records of any diving duck species in Central America in the months of June through Sep- tember are almost non-existent. Photograph by Jafeth Zablah. Pearl Kite continues to expand its range northward through Central America, having reached Honduras and El Salvador as recently as spring 2009. While no longer a rare sight in Honduras's Pacifc lowlands, this individual was found well inland near Salalica, where the species is still quite rare. Photograph by Jefrey López Canaca. Typically a vagrant in Panama, and rare even in El Niño years, this Gray Gull appeared along the coast south of Pacora on 19 June 2014. Photograph by Rosabel Miró. North America's second record of Pearly-breasted Cuckoo involved a pair found nesting at the Río Mono Bridge on the Inter-American Highway in Panama. First seen 12 July 2014, a pair was observed building a nest on 25 July (one shown here), and a bird was seen incubating on 30 July. The only previous North American record was from Sombrero Island in the north- ern Lesser Antilles in 1863. Photograph by Euclides Campos.
