V O L U M E 7 0 ( 2 0 1 9 ) • N U M B E R S 3 / 4 395 Very rare in spring on the Belizean cayes, Black-whiskered Vireo is a great find among the waves of more common migrants. This individual was at Northeast Caye, Glovers Reef Atoll, 20 April 2016. Photo by © Yves Scholten This vagrant Amazilia Hummingbird, likely belonging to the southern leucophoae subspecies, was about 1400 km north of its Peruvian range, and a first for North America. It was in a dry forest on the Pacific coast of Coclé, Panama on 16 March. Photos by © Susan Hengeveld C E N T R A L A M E R I C A cycle bird seen 31 Mar at Belize City Municipal Airport (ph. FC). Reports of Kelp Gull, practi - cally unknown in Central America before 2000, have increased in recent years. One was reported at Costa del Este (Panama City) on 9 Apr (DB, DG). Inca Tern is sometimes observed in south - ern Central America, especially in El Niño years. Perhaps as a result of an exceptionally strong but at this point already waning El Niño, one was discovered on the Pacific side of the Panama Canal on 1 May (VW), where it remained pres - ent until 3 May (m. obs.). An Arctic Tern in its first summer, apparently the first ever recorded on the Caribbean coast of Central America, was seen with Laughing Gulls and a Common Tern (with which it was directly compared) on the Be - lize City Southern Foreshore on 14 Jul (ph. RM). A Forster's Tern was a good find in the Montijo Bay near Santa Catalina, southern Veraguas (Pan - ama) on 11 Mar (AJ, ML, KG). A Smooth-billed Ani well studied in Belize City 21 Jul (PB, FP, ph. RM, VR) provided one of the few records of this species from the Belize mainland. The closest established populations are on Cozumel Is (Yucatan) and the Bay Islands of Honduras. A Black-billed Cuckoo on 21 April (ph. WO, JvD, EE, OK) at Pico Bonito in Hon - duras was not completely unexpected, but was nonetheless the first north coast record for all of Honduras. The status of Flammulated Owl east of the Isthmus of Tehuantepec is poorly known, with no recent documented records in Central America. Thus, a report of breeding from Hue - huetenango is extraordinary. One individual was present at Laguna Ordoñez on 6 Apr (EM, JM), 7 May (EM, DA), and 8 May (ph. JPC, RC, CE) at what was presumed to be a breeding site. Almost as exciting was Belize's 3rd record of Burrowing Owl seen in the savannas west of Crooked Tree Village on 9 (FT) and 27 Mar (ph. RM). The first record was of 2 birds collected along the central coast in Jan 1901 by M. E. Peck. Nearly a cen - tury later in 1998, one was seen by Jan Meerman at a quarry site near Indian Creek Village, Toledo. Another nocturnal species whose status in Central America is practically unknown is Spot- tailed Nightjar, a savanna species that is thought to be a visiting breeder in Mexico and parts of Central America and a year-round resident in South America. Two individuals were heard singing on 7 May at Santa Cruz de Yojoa (v.rec. RRo), where they were still present on 23 (RRo) and 28 May (m. obs.). In Honduras, this species was previously known from two old specimens at Lake Yojoa and a few undocumented reports. Chuck-will's-widow, a migratory species rarely reported from El Salvador, was observed on 24 Mar at Ecoparque El Espino in La Libertad (ph. EH). Mexican Whip-poor-will was finally doc - umented in Nicaragua, in mountains along the Honduran border above 1400 m on 4 and 6 Jun in the Dipilto Jalapa nature reserve, Nueva Sego - via (MRo). Two birds were calling on 10 Jun. Another individual was nearby on 16 Jun (JCo). Oilbird is occasionally reported from Costa Rica and Panama, usually in humid montane or cloud forest, and from June to October. One fly - ing around the shores of the Panama Canal near the town of Gamboa on 13 Mar was especially surprising (BA). More than a month later, one was found on a day roost in Gamboa on 25 Apr (m. obs.), where it was relocated the next day. White-chinned Swift continues as a breeding bird in Panama, with an active nest in Boquette, Chiriqui on 23 May (ph. JL), at the same loca - tion where it was first found breeding in 2014. Uncommon to rare anywhere in Belize, a female Black-crested Coquette seen 7 Apr at Black Rock Lodge in w. Cayo (IMo) was well north of its typical range in Toledo and Stann Creek. A Plain- capped Starthroat photographed at El Remate on 14 Apr (ph. JPC, ABL) appears to be the first record for Petén, Guatemala. The most amazing find of the season, if not the year, is an Amazilia Hummingbird some 1,400 km out of range, near Juan Hombron, Coclé, 16 Mar in Panama (JH, ph. SH). It is presumed to have been a va - grant from the coastal lowlands of western South America. Studies of the photos suggest the leuco - phaea subspecies, native to NW Peru. Expanding its range northward across Nica- ragua, and long expected to appear in Hondu- ras, six Crimson-fronted Parakeets did indeed appear near Rus-Rus in the Honduran Moskitia on 19 May (ph. LKJ), providing a first record for Honduras. A group of six individuals was photographed six days later and 20 km further east, close to the border with Nicaragua, by the same observer. PASSERINES A Fasciated Antshrike at Pico Bonito Lodge on 6 Mar (LW and m. obs.) was outside the known range by 150 km and a first documented re - cord for Atlántida. An Eastern Wood-Pewee on Little Water Caye, Stann Creek on 8 Jun (ph. RM) provided the latest spring record for Be - lize. A White-throated Flycatcher was at Daw- son Creek, Orange Walk on 3 and 31 Mar (ER) and 1 Apr (AS). Other than Sylvester Village in w. Orange Walk where 1-2 were reported annu - ally from the late 1980s through the mid- to late 1990s and The Dump, Toledo, where it has been reported annually since 2004, there are few verified records from Belize. Providing the first breeding record for Belize, a pair of Gray King - birds was observed on multiple occasions in Jun and early July at St. John's College in Belize City (ph. FC, m. obs.). On 4, 6, and 8 Jun a nest - ling was observed (PB, DC, & ER, respectively), but it is not known if the bird fledged. What was presumed to be the same pair was observed "possibly nest building" nearby on 13 Jul (PB, FP, RM) suggesting an attempt at a 2nd brood. Also noteworthy was an apparently different pair observed 2 km se. of St. John's College on 14 Jul (ph. RM, PB, FP, JE, VR, DL). New for Honduras but expected to occur oc- casionally on the Bay Islands in migration, was Black-whiskered Vireo, which was seen on Southwest Cay off Guanaja, Islas de la Bahía on 12 Apr (ph. RRu). A week later, one was present on Northeast Caye, Glovers Reef Atoll on 20 and 22 Apr (ph. YS), providing Belize with its sev - enth record. In Belize, Yucatan Vireo is restricted to the cayes and immediate coast, with an occa - sional "stray" a few kilometers inland. Therefore, one well studied at Black Rock Lodge near the Guatemala border on 22 Apr (DC, FP, EP, CB) was a complete surprise. Thirty Purple Martins seen at a pond in Ladyville, Belize on 18 Jun (PB) were early fall migrants. Every year, Purple Mar - tins are reported in the Belize City area the last
