V O L U M E 7 0 ( 2 0 1 8 ) • N U M B E R 2 239 C E N T R A L A M E R I C A waters was noted as far south as Ecuador this season, potentially related to exception- ally strong El Niño conditions in the e. Pa- cific during that time. Franklin's Gulls are unusual in winter along the Pacific coast of Central America, so 2 photographed at La- guna Chichoj, Alta Verapaz, Guatemala 4 & 5 Dec (MN, LN) served as an especially noteworthy inland record. A Ring-billed Gull photographed at Flores, Petén 19 Dec (DA, JPC) represents one of only a handful of records in Guatemala. White Tern, a species of tropical oceans, is extremely rare in the Region's coastal waters. Thus, an individual photographed near Jicaral, Puntarenas, Costa Rica 13 Jan (ph. JM) was quite unexpected. Sooty Tern is another species rarely seen from shore, and coastal records often per- tain to sickly individuals. A juv. found on driftwood at the Refugio Nacional de Fauna Silvestre Barra del Colorado, Limón 10 Sep (JAZ) was noteworthy for Costa Rica. Unex- pected away from the coast, and especially along a forested inland river, was a Common Tern on the Belize R. in Guanacaste N.P., just north of Belmopan, Cayo 4 Feb (ph. MT). This observation apparently establishes the first confirmed record away from the imme- diate coast in Belize and one of few inland of a coastal waterway on the Caribbean slope of Central America. A Black Skimmer found at Fresh Catch Fish Farm, 25 km inland in Belize and near the Cayo border 31 Dec (RM) was unexpected. This species, a less-than-annual visitor to Belize, is typically con- fined to the immediate coastline. There was only one previous in- land record, also at Fresh Catch Fish Farm 9 Nov 2013. DOVES THROUGH MUNIAS Eurasian Collared-Dove, while now becoming established in northern Central America, is still a rarity in the southern half of the region. The first photo-doc- umented record for Costa Rica was found at Finca 7 in Sierpe, Puntarenas 20 Feb (ph. JT). Late, migrant Yellow-billed Cuckoos were noted on 1 Dec at the Uni- versity of Costa Rica campus in San José (ph. RJ) and at Cattle Landing near Punta Gorda, Be- lize 5 Dec (IM). Also in Belize, an individual likely overwintering was seen near Lamanai Outpost Lodge, Orange Walk 15 Feb (ER, BC, ph. PF). All previous records in Belize have referred to mi- grants during Apr to early-Jun and late-Aug to late-Nov. A Dwarf Cuckoo near Yaviza, Darién 1 Feb (ph. DW, IQ) was the fifth re- ported for Panama, but represented the first photo-documented record for North Amer- ica. Great Horned Owl, while not uncom- mon north of Costa Rica and to the south in Colombia, is nevertheless the rarest owl in southern Central America. One was heard at an elevation of 2800m on the Irazu Vol- cano, Cartago, Costa Rica 27 Dec (CA, ErC). An Unspotted Saw-whet Owl was found at elevations above 3000m on the Baru Vol- cano, Chiriquí, Panama 2 Feb (JL), the only known location for the species in that coun- try. Brown Violetear is a fairly common resi- dent at higher elevations in the Maya Mtns. of Belize and is occasionally seen in the foot - hills, but seldom in the lowlands. One seen near sea level along the Wari Loop trail at Cockscomb Basin Wildlife Sanctuary 8 Feb (GC) provided one of the few records for the country below the foothills. Aplomado Fal - con occasionally turns up in Costa Rica. A juv. was noted at Filadelfia, Guanacaste 28 Jan (ph. AK). Bat Falcon is even rarer in El Salvador, where one was observed near Za- potal 6 Dec (MB, ph. JA), providing the first record for Cuscatlán and only the second re- cord for El Salvador in the last 15 years. Wintering unusually far south were a White-eyed Vireo at San Antonio de Tur- rialba, Cartago, Costa Rica 1 Jan (ph. PO) and 2 Blue-headed Vireos also in Costa Rica: one at Lands in Love Hotel in San Ramón, Alajuela 10 Feb (PO), and the other at the Trogon Lodge in San Gerardo de Dota, San José (JC). Conversely, a Red-eyed Vireo re- ported at Tikal (Petén), Guatemala 28 Jan (JSc), 8 (MaC, ST) & 13-14 Feb (JPC, ABL, MiB) was wintering much farther north than is typical for that species. Providing a first record for Belize was a well-studied Bell's Vireo believed to be of the distinctive, nominate (Eastern) subspecies bellii, near Lamanai Outpost Lodge 10 Feb (LS, MP). A female Purple Martin, most likely a late fall migrant and seen at the Dump, Toledo 2 Dec (EmC, ph. HB) provided a first Dec record for Belize and for Central America north of Panama. A Tree Swallow seen over Laguna de Tisma, Masaya, Nicaragua 21 Feb (CW, TS, BH, LJ, MT, ph. CW) was noteworthy, as the species is rarely reported in Nicara- gua. Cave Swallow is a rare but increasingly regular winter visitor to Costa Rica. Two were seen near Chomes, Puntarenas 21 Jan (JZ), while 6 were observed at the Ensenada Lodge near Manzanillo, Guanacaste 14 Feb (LG). Bicolored Wren appears to be spread- ing westward in e. Panama. This species, of- ten found in disturbed areas, was new for Panama in 2012 but is now regular in the Yaviza area. A report near Peñitas, Darién (DW) 3 Feb served as the latest piece of evi- dence pointing toward this westward trend. A Gray-cheeked/Bicknell's Thrush observed This immature Gray Hawk was new for Panama when discovered on 27 Janu- ary. It was found not far from the Costa Rican border, in an area where Gray- lined Hawk does not occur, and represents the easternmost record for this species. Gray Hawk has spread eastward on the Caribbean coast of Costa Rica in recent years, and has now reached Panama. Photo by © Natalia Decastro. Dwarf Cuckoo has previously occurred a few times in Panama, but this individual, found on 1 February near Yaviza in the Darién Province, was the first to be photo- graphed.
