  • Sierra Leone Rockfowl and Upper Guinea Specials 21St February to 7Th March 2022 (15 Days)
    Sierra Leone Rockfowl and Upper Guinea Specials 21st February to 7th March 2022 (15 days) White-necked Rockfowl by Adam Riley RBL Sierra Leone Itinerary 2 Sierra Leone is a core West African destination, offering visitors a diverse range of exciting Upper Guinea forest birds and mammals. Rockjumper pioneered this tour during reconnaissance trips in 2005 and then led three successful tours in the course of 2006; these being the first-ever birding tours to the country. Sierra Leone’s biologically rich rainforests support no less than 15 of the 16 Upper Guinea endemic bird species, including the fabled White-necked Rockfowl that will form the basis of our tour. Forest specialties abound and we will focus on finding the rare Gola Malimbe, Sierra Leone Prinia, Black-headed Rufous Warbler, Hartlaub’s Duck, Brown-cheeked Hornbill, Sharpe’s Apalis, Kemp’s Longbill, White-breasted Guineafowl and Red-cheeked Wattle-eye; while the wooded savannas are home to the stunning Emerald Starling, Crimson Seedcracker and Turati’s Boubou, to name but a few.

  • Comments on the Ornithology of Nigeria, Including Amendments to the National List
    Robert J. Dowsett 154 Bull. B.O.C. 2015 135(2) Comments on the ornithology of Nigeria, including amendments to the national list by Robert J. Dowsett Received 16 December 2014 Summary.—This paper reviews the distribution of birds in Nigeria that were not treated in detail in the most recent national avifauna (Elgood et al. 1994). It clarifies certain range limits, and recommends the addition to the Nigerian list of four species (African Piculet Verreauxia africana, White-tailed Lark Mirafra albicauda, Western Black-headed Batis Batis erlangeri and Velvet-mantled Drongo Dicrurus modestus) and the deletion (in the absence of satisfactory documentation) of six others (Olive Ibis Bostrychia olivacea, Lesser Short-toed Lark Calandrella rufescens, Richard’s Pipit Anthus richardi, Little Grey Flycatcher Muscicapa epulata, Ussher’s Flycatcher M. ussheri and Rufous-winged Illadopsis Illadopsis rufescens). Recent research in West Africa has demonstrated the need to clarify the distributions of several bird species in Nigeria. I have re-examined much of the literature relating to the country, analysed the (largely unpublished) collection made by Boyd Alexander there in 1904–05 (in the Natural History Museum, Tring; NHMUK), and have reviewed the data available in the light of our own field work in Ghana (Dowsett-Lemaire & Dowsett 2014), Togo (Dowsett-Lemaire & Dowsett 2011a) and neighbouring Benin (Dowsett & Dowsett- Lemaire 2011, Dowsett-Lemaire & Dowsett 2009, 2010, 2011b). The northern or southern localities of species with limited ranges in Nigeria were not always detailed by Elgood et al. (1994), although such information is essential for understanding distribution patterns and future changes. For many Guineo-Congolian forest species their northern limit in West Africa lies on the escarpment of the Jos Plateau, especially Nindam Forest Reserve, Kagoro.

Systematic notes on Asian birds. 28. Taxonomic comments on some south and south-east Asian members of the family Nectariniidae. Zool. Verh. Leiden 340, 27.xii.2002: 179-189.— ISSN 0024-1652/ISBN 90-73239-84-2. Clive F. Mann, 53 Sutton Lane South, London W4 3JR, U.K. (e-mail: [email protected]). Keywords: Asia; Nectariniidae; taxonomy. Certain taxonomic changes made by Cheke & Mann (2001) are here explained and justified. Dicaeum haematostictum Sharpe, 1876, is split from D. australe (Hermann, 1783). D. aeruginosum Bourns & Worcester, 1894 is merged into D. agile (Tickell, 1833). The genus Chalcoparia Cabanis, 1851, is re-estab- lished for (Motacilla) singalensis Gmelin, 1788. The taxon Leptocoma sperata marinduquensis (duPont, 1971), is shown to be based on a specimen of Aethopyga siparaja magnifica Sharpe, 1876. Aethopyga vigor- sii (Sykes, 1832) is split from A. siparaja (Raffles, 1822). Cheke & Mann (op. cit.) mistakenly omitted two forms, Anthreptes malacensis erixanthus Oberholser, 1932 and Arachnothera longirostra zarhina Ober- holser, 1912. Five subspecies are removed from Aethopyga shelleyi Sharpe, 1876 to create the polytypic A. bella, Tweeddale, 1877. The Arachnothera affinis (Horsfield, 1822)/modesta (Eyton, 1839)/everetti (Sharpe, 1893) complex is re-evaluated in the light of the revision by Davison in Smythies (1999). Introduction In a recent publication (Cheke & Mann, 2001) some taxonomic changes were made to members of this family occurring in Asia.

  • 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.

  • A Classification of the Rallidae
    A CLASSIFICATION OF THE RALLIDAE STARRY L. OLSON HE family Rallidae, containing over 150 living or recently extinct species T and having one of the widest distributions of any family of terrestrial vertebrates, has, in proportion to its size and interest, received less study than perhaps any other major group of birds. The only two attempts at a classifi- cation of all of the recent rallid genera are those of Sharpe (1894) and Peters (1934). Although each of these lists has some merit, neither is satisfactory in reflecting relationships between the genera and both often separate closely related groups. In the past, no attempt has been made to identify the more primitive members of the Rallidae or to illuminate evolutionary trends in the family. Lists almost invariably begin with the genus Rdus which is actually one of the most specialized genera of the family and does not represent an ancestral or primitive stock. One of the difficulties of rallid taxonomy arises from the relative homo- geneity of the family, rails for the most part being rather generalized birds with few groups having morphological modifications that clearly define them. As a consequence, particularly well-marked genera have been elevated to subfamily rank on the basis of characters that in more diverse families would not be considered as significant. Another weakness of former classifications of the family arose from what Mayr (194933) referred to as the “instability of the morphology of rails.” This “instability of morphology,” while seeming to belie what I have just said about homogeneity, refers only to the characteristics associated with flightlessness-a condition that appears with great regularity in island rails and which has evolved many times.

  • Birding Tour to Ghana Specializing on Upper Guinea Forest 12–26 January 2018
    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.

    Zambia and Zimbabwe 28 ovember – 6 December 2009 Guide: Josh Engel A Tropical Birding Custom Tour All photos taken by the guide on this tour. The Smoke that Thunders: looking down one end of the mile-long Victoria Falls. ITRODUCTIO We began this tour by seeing one of Africa’s most beautiful and sought after birds: African Pitta . After that, the rest was just details. But not really, considering we tacked on 260 more birds and loads of great mammals. We saw Zambia’s only endemic bird, Chaplin’s Barbet , as well as a number of miombo and broad-leaf specialties, including Miombo Rock-Thrush, Racket-tailed Roller, Southern Hyliota, Miombo Pied Barbet, Miombo Glossy Starling, Bradfield’s Hornbill, Pennant-winged ightjar, and Three-banded Courser. With the onset of the rainy season just before the tour, the entire area was beautifully green and was inundated with migrants, so we were able to rack up a great list of cuckoos and other migrants, including incredible looks at a male Kurrichane Buttonquail . Yet the Zambezi had not begun to rise, so Rock Pratincole still populated the river’s rocks, African Skimmer its sandbars, and Lesser Jacana and Allen’s Gallinule its grassy margins. Mammals are always a highlight of any Africa tour: this trip’s undoubted star was a leopard , while a very cooperative serval was also superb. Victoria Falls was incredible, as usual. We had no problems in Zimbabwe whatsoever, and our lodge there on the shores of the Zambezi River was absolutely stunning. The weather was perfect throughout the tour, with clouds often keeping the temperature down and occasional rains keeping bird activity high.
