RO•WER TUE family Caprimulgidae consistsof about 73 speciesof nocturnal and crepuscularbirds commonly called nightjars from their persistent penetratingnocturnal calls. They are divided into. two subfamilies,the Chordeilinae,a group of 8 New World species,and the Caprimulginae,a group of approximately65 speciesoccurring in most of the warmer land areasof the world. The chordeilinesare largelycrepuscular in their habits, somespecies being active on overcastor, occasionally,sunny days; most of the caprimulginesare much more nocturnal than the chordeilines.The Chuck-will's-widow(Caprimulgus carolinensis) is the largestmember of its genus,which contains some 40. African, Eurasian,and New World species (Peters, 1940). It is a commonbreeding bird of the deciduousforests of the southern third of eastern North America, and winters largely in the Antilles, Central America,and the southernmostareas of eastern North America. The sequenceof molt has been describedfor several African and Eurasian caprimulgines(Verheyen, 1956; Stresemannand Stresemann, 1966) and partially describedfor the chordeilineCommon Nighthawk (Chordeilesminor) by Selander(1954). Someintriguing variations exist in the sequenceand timing of molts amongthe caprimulgiforms(Strese- mann and Stresemann,1966; Rohwer, MS on Phalaenoptilusnuttallii), and knowledgeof the sequenceand time of feather replacement for more caprimulgiforms,coupled

  • Ghana Mega Rockfowl & Upper Guinea Specials 3 to 25 January 2016 (23 Days) Trip Report
    Knox Ghana Mega Rockfowl & Upper Guinea Specials 3 to 25 January 2016 (23 days) Trip Report Akun Eagle-Owl by David Hoddinott Trip Report compiled by Tour Leader Markus Lilje RBT Knox Ghana Mega Trip Report January 2015 2 Trip Summary Our private Ghana Mega trip proved yet again to be a resounding success! We notched up a fantastic species total in 23 days, where we covered the length and breadth of the country and a great variety of habitats in this superb West African country! Our tour started off with a visit to Shai Hills. This small but fabulous reserve has a nice variety of habitats including mixed woodland, grassland, wetlands and granite outcrops and therefore supports an interesting array of bird species. During our morning exploring the reserve we recorded African Cuckoo-Hawk, Western Marsh Harrier, Red-necked Buzzard, stunning Violet Turaco, numerous immaculate Blue-bellied Roller, Vieillot’s and Double-toothed Barbets, Senegal and African Wattled Lapwings, White-shouldered Black Tit, Red- shouldered Cuckooshrike, Black-bellied Bustard, Senegal Parrot, Senegal Batis and restless Senegal Eremomela. A number of migrants were seen including Willow Warbler, Whinchat and Spotted Flycatcher. Even mammals showed well for us as we had a number of Kob, Bushbuck, Olive Baboon, Callithrix Monkey and unusually good views of Lesser Spot- Blue-bellied Roller by Markus Lilje nosed Monkey! Well pleased with our morning’s birding, we left Shai Hills and made our way to Ho. En route we stopped for lunch near the Volta Dam where we enjoyed most memorable close-up encounters with Mangrove Sunbird and Bronze- tailed Starling.

    Birding Tour to Ghana Specializing on Upper Guinea Forest 12–26 January 2018 Chocolate-backed Kingfisher, Ankasa Resource Reserve (Dan Casey photo) Participants: Jim Brown (Missoula, MT) Dan Casey (Billings and Somers, MT) Steve Feiner (Portland, OR) Bob & Carolyn Jones (Billings, MT) Diane Kook (Bend, OR) Judy Meredith (Bend, OR) Leaders: Paul Mensah, Jackson Owusu, & Jeff Marks Prepared by Jeff Marks Executive Director, Montana Bird Advocacy Birding Ghana, Montana Bird Advocacy, January 2018, Page 1 Tour Summary Our trip spanned latitudes from about 5° to 9.5°N and longitudes from about 3°W to the prime meridian. Weather was characterized by high cloud cover and haze, in part from Harmattan winds that blow from the northeast and carry particulates from the Sahara Desert. Temperatures were relatively pleasant as a result, and precipitation was almost nonexistent. Everyone stayed healthy, the AC on the bus functioned perfectly, the tropical fruits (i.e., bananas, mangos, papayas, and pineapples) that Paul and Jackson obtained from roadside sellers were exquisite and perfectly ripe, the meals and lodgings were passable, and the jokes from Jeff tolerable, for the most part. We detected 380 species of birds, including some that were heard but not seen. We did especially well with kingfishers, bee-eaters, greenbuls, and sunbirds. We observed 28 species of diurnal raptors, which is not a large number for this part of the world, but everyone was happy with the wonderful looks we obtained of species such as African Harrier-Hawk, African Cuckoo-Hawk, Hooded Vulture, White-headed Vulture, Bat Hawk (pair at nest!), Long-tailed Hawk, Red-chested Goshawk, Grasshopper Buzzard, African Hobby, and Lanner Falcon.

  • Birds of Reserva Natural Laguna Blanca, Departamento San Pedro, Paraguay and the Imminent Threats to Their Conservation

Results: A total of 301 species are recorded from the reserve, with an additional 18 species known to occur in the catchment area, already declared an Important Bird Area. Thirty four species are reported for the first time in the reserve.Conclusions: The presence of breeding populations of a number of threatened Cerrado birds makes the long term conservation of this site a priority for conservation in Paraguay. However the protected status of the reserve officially ended in January 2015 and the imminent threats that this vitally important bird area faces are detailed. Keywords: Cerrado, Eleothreptus candicans, IBA, Inventory, Grasslands. Resumen Objetivo: Se presentan los resultados de varios años de trabajos de inventario en la Reserva Natural Laguna Blanca, departamento San Pedro, Paraguay. Resultados: Un total de 301 especies de aves han sido registradas en la reserva, han sido comprobadas 18 más en la zona de amortiguamiento (oficialmente declarado un AICA). Treinta y cuatro especies se reportan por primera vez en la zona. Conclusiones: La presencia de poblaciones reproductivas de aves amenazadas del Cerrado indica que la conservación a largo plazo de esta reserva debe ser una prioridad para la conservación en Paraguay.

  • Breeding Biology of the White-Winged Nightjar (Eleothreptus Candicans) in Eastern Paraguay
    Revista Brasileira de Ornitologia, 22(2), 219-233 ARTICLE June 2014 Breeding biology of the White-winged Nightjar (Eleothreptus candicans) in eastern Paraguay Robert G. Pople Department of Zoology, University of Cambridge, Downing Street, Cambridge, CB2 3EJ, UK. Email: [email protected] Current address: BirdLife International, Wellbrook Court, Girton Road, Cambridge, CB3 0NA, UK. Received on 03 September 2013. Accepted on 02 October 2013. ABSTRACT: Breeding biology of the White-winged Nightjar (Eleothreptus candicans) in eastern Paraguay. I present the first detailed description of the breeding biology of the White-winged Nightjar (Eleothreptus candicans), based on data collected over three breeding seasons during 1998-2001 at Aguará Ñu, Canindeyú, eastern Paraguay. Male nightjars defended small territories situated on the upper slopes of ridgelines. Each territory contained one or more “display arenas” at which the male performed nuptial display flights. Aggregation indices confirmed that the primary display arenas of males were significantly clustered within the survey area. Within their territories, males apparently selected display arenas on the basis of their structural characteristics: mounds used as arenas were significantly lower and broader than random mounds. Males engaged in display activity from late August to early January. On average, males performed 0.54 ± 0.04 display flights per minute during nocturnal focal watches, but there was considerable intra-male variation in display rate. Following a burst of activity immediately after their arrival at display arenas at dusk, male display rate was best explained by ambient levels of moonlight. Males produced a previously undescribed insect-like “tik tik” call when inactive on their territories.
