Regular daily contact and forewarning the gorillas ofone' s imminent arrival are thetw o most important factors inpromotin g habituation inwester n lowland gorillas. this thesis 4.Notwithstandin g the potential oftouris m togenerat e substantial revenues for protected areas, itwil l never generate enough to sustainably and sufficiently manage those inth e Guinean-Congolian Forest Region. this thesis 5. Given thepoo r economic development of most ofth e countries ofth e Guinean-Congolian Forest Region,th e international community isgoin g to havet o pay the costs ofbiodiversit y protection in this region. this thesis 6.

Lombard Graduate Institute of International and Development Studies 47 Avenue Blanc, 1202 Geneva, Switzerland p +41 22 908 5777 f +41 22 732 2738 e [email protected] w www.smallarmssurvey.org THE CENTRAL AFRICAN REPUBLIC AND SMALL ARMS A REGIONAL TINDERBOX ‘ The Central African Republic and Small Arms is the most thorough and carefully researched G. Eric By Berman with Louisa N. Lombard report on the volume, origins, and distribution of small arms in any African state. But it goes beyond the focus on small arms. It also provides a much-needed backdrop to the complicated political convulsions that have transformed CAR into a regional tinderbox. There is no better source for anyone interested in putting the ongoing crisis in its proper context.’ —Dr René Lemarchand Emeritus Professor, University of Florida and author of The Dynamics of Violence in Central Africa ’The Central African Republic, surrounded by warring parties in Sudan, Chad, and the Democratic Republic of the Congo, lies on the fault line between the international community’s commitment to disarmament and the tendency for African conflicts to draw in their neighbours. The Central African Republic and Small Arms unlocks the secrets of the breakdown of state capacity in a little-known but pivotal state in the heart of Africa. It also offers important new insight to options for policy-makers and concerned organizations to promote peace in complex situations.’ —Professor William Reno Associate Professor and Director of Graduate Studies, Department of Political Science, Northwestern University Photo: A mutineer during the military unrest of May 1996.

  • 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.

Black Bee-eater 2. Standard-winged Nightjar 3. Northern Carmine Bee-eater 4. Blue-headed Bee-eater 5. African Piculet 6. Great Blue Turaco 7. Little Bee-eater 8. African Blue Flycatcher 9. Chocolate-backed Kingfisher 10. Beautiful Sunbird RBT Ghana Trip Report February 2007 2 Tour Summary This classic tour combining the best rainforest sites, national parks and seldom explored northern regions gave us an incredible overview of the excellent birding that Ghana has to offer. This trip was highly successful, we located nearly 400 species of birds including many of the Upper Guinea endemics and West Africa specialties, and together with a great group of people, we enjoyed a brilliant African birding adventure. After spending a night in Accra our first morning birding was taken at the nearby Shai Hills, a conservancy that is used mainly for scientific studies into all aspects of wildlife. These woodland and grassland habitats were productive and we easily got to grips with a number of widespread species as well as a few specials that included the noisy Stone Partridge, Rose-ringed Parakeet, Senegal Parrot, Guinea Turaco, Swallow-tailed Bee-eater, Vieillot’s and Double- toothed Barbet, Gray Woodpecker, Yellow-throated Greenbul, Melodious Warbler, Snowy-crowned Robin-Chat, Blackcap Babbler, Yellow-billed Shrike, Common Gonolek, White Helmetshrike and Piapiac. Towards midday we made our way to the Volta River where our main target, the White-throated Blue Swallow showed well.

  • Biogeography of the Reptiles of the Central African Republic
    African Journal of Herpetology, 2006 55(1): 23-59. ©Herpetological Association of Africa Original article Biogeography of the Reptiles of the Central African Republic LAURENT CHIRIO AND IVAN INEICH Muséum National d’Histoire Naturelle Département de Systématique et Evolution (Reptiles) – USM 602, Case Postale 30, 25, rue Cuvier, F-75005 Paris, France This work is dedicated to the memory of our friend and colleague Jens B. Rasmussen, Curator of Reptiles at the Zoological Museum of Copenhagen, Denmark Abstract.—A large number of reptiles from the Central African Republic (CAR) were collected during recent surveys conducted over six years (October 1990 to June 1996) and deposited at the Paris Natural History Museum (MNHN). This large collection of 4873 specimens comprises 86 terrapins and tortois- es, five crocodiles, 1814 lizards, 38 amphisbaenids and 2930 snakes, totalling 183 species from 78 local- ities within the CAR. A total of 62 taxa were recorded for the first time in the CAR, the occurrence of numerous others was confirmed, and the known distribution of several taxa is greatly extended. Based on this material and an additional six species known to occur in, or immediately adjacent to, the coun- try from other sources, we present a biogeographical analysis of the 189 species of reptiles in the CAR. Key words.—Central African Republic, reptile fauna, biogeography, distribution. he majority of African countries have been improved; known distributions of many species Tthe subject of several reptile studies (see are greatly expanded and distributions of some for example LeBreton 1999 for Cameroon). species are questioned in light of our results.
