Hunters shoot and trap animals, which are trans- umans have hunted for subsistence in the forests ported to rural and urban markets for sale.

  • A Multigene Phylogeny of Galliformes Supports a Single Origin of Erectile Ability in Non-Feathered Facial Traits
    J. Avian Biol. 39: 438Á445, 2008 doi: 10.1111/j.2008.0908-8857.04270.x # 2008 The Authors. J. Compilation # 2008 J. Avian Biol. Received 14 May 2007, accepted 5 November 2007 A multigene phylogeny of Galliformes supports a single origin of erectile ability in non-feathered facial traits Rebecca T. Kimball and Edward L. Braun R. T. Kimball (correspondence) and E. L. Braun, Dept. of Zoology, Univ. of Florida, P.O. Box 118525, Gainesville, FL 32611 USA. E-mail: [email protected] Many species in the avian order Galliformes have bare (or ‘‘fleshy’’) regions on their head, ranging from simple featherless regions to specialized structures such as combs or wattles. Sexual selection for these traits has been demonstrated in several species within the largest galliform family, the Phasianidae, though it has also been suggested that such traits are important in heat loss. These fleshy traits exhibit substantial variation in shape, color, location and use in displays, raising the question of whether these traits are homologous. To examine the evolution of fleshy traits, we estimated the phylogeny of galliforms using sequences from four nuclear loci and two mitochondrial regions. The resulting phylogeny suggests multiple gains and/or losses of fleshy traits. However, it also indicated that the ability to erect rapidly the fleshy traits is restricted to a single, well-supported lineage that includes species such as the wild turkey Meleagris gallopavo and ring-necked pheasant Phasianus colchicus. The most parsimonious interpretation of this result is a single evolution of the physiological mechanisms that underlie trait erection despite the variation in color, location, and structure of fleshy traits that suggest other aspects of the traits may not be homologous.

A check list of the helminths of guineafowls (Numididae) and a host list of these parasites. Onderstepoort Journal of Veterinary Research, 74:315–337 Published and personal records have been compiled into a reference list of the helminth parasites of guineafowls. Where data on other avian hosts was available these have been included for complete- ness’ sake and to give an indication of host range. The parasite list for the Helmeted guineafowls, Numida meleagris, includes five species of acanthocephalans, all belonging to a single genus, three trematodes belonging to three different genera, 34 cestodes representing 15 genera, and 35 nema- todes belonging to 17 genera. The list for the Crested guineafowls, Guttera edouardi, contains a sin- gle acanthocephalan together with 10 cestode species belonging to seven genera, and three nema- tode species belonging to three different genera. Records for two cestode species from genera and two nematode species belonging to a single genus have been found for the guineafowl genus Acryllium. Of the 70 helminths listed for N. meleagris, 29 have been recorded from domestic chick- ens.

  • Vocal Behavior of Crested Guineafowl (Guttera Edouardi) Based on Visual
    van Niekerk Avian Research (2015) 6:13 DOI 10.1186/s40657-015-0022-1 RESEARCH Open Access Vocal behavior of Crested Guineafowl (Guttera edouardi) based on visual and sound playback surveys in the Umhlanga Lagoon Nature Reserve, KwaZulu-Natal province, South Africa Johann H. van Niekerk Abstract Background: Generally speaking, playbacks were often ineffective to determine the group sizes of birds since mainly males from leks responded. This limitation has not been tested properly for flocking birdssuchasCrestedGuineafowl (Guttera edouardi) with the view to use it as a counting method. The aims of the study reported in this paper were (1) to describe the calls of Crested Guineafowl in a social context; (2) to interpret calls in an evolutionary context; and (3) to demonstrate that playbacks can be used to locate and count Crested Guineafowl in small isolated forests. Methods: The vocal behavior of Crested Guineafowl was observed during a survey conducted in the Umhlanga Lagoon Nature Reserve (KwaZulu-Natal, South Africa) from November 2010 to June 2012. Transect line observations and sound playback methods were used. Results: The behavioral context and structure of calls were described. The eight calls described for Crested Guineafowl were produced mainly to unite flock members in the dense understory, where visibility was poor, and to repel intruders. When not disturbed, Crested Guineafowl were quiet and only made soft contact calls. Conclusions: Thehighrateofcallbackandthefactthatflocksinvariablyapproachthesourceofthecallen masse, shows

  • Kenya: Birds and Other Wildlife, Custom Trip Report
    Kenya: Birds and Other Wildlife, custom trip report August 2014 Silvery-cheeked Hornbill www.birdingecotours.com [email protected] 2 | T R I P R E P O R T Custom Tour Kenya August 2014 Kenya lies across the equator, ranging in altitude from 5199 m to sea level. The country’s topography and climate are highly varied, hence it exhibits many different habitats and vegetation types. Huge populations of wildlife are concentrated in protected areas, mainly national parks, national reserves, and conservancies. However, there are also opportunities to find a wealth of biodiversity in non-protected areas, as for example in Important Bird Areas (IBAs), some of which are found in non-protected areas, while others are located in protected areas. The IBAs provide a good chance to see some of the national or regional endemic species of both flora and fauna. They also provide opportunities for visitors to interact with local populations, which might be sharing their knowledge of indigenous life and traditional lifestyles. Our 15-day safari took us through unique and pristine habitats, ranging from the coastal strip of the Indian Ocean and its dry forest to the expansive savanna bushland of Tsavo East National Park, the semiarid steppes of Samburu National Park in northern Kenya, the mountain range of the Taita Hills, tropical rainforests, and Rift Valley lakes, before ending in the Masai Mara in southwestern Kenya. The variance of these habitats provided unique and rich wildlife diversity. Nairobi The city of Nairobi has much to offer its visitors. The Nairobi National Park is just seven kilometers away from the city and offers lots of wildlife.

Box 40658 GPO Nairobi Contact email: [email protected] 1 KEY PROJECT OUTPUTS/MILE STONES 1. Involvement of local community members as field assistants enhanced capacity building, created awareness on the conservation of birds/biodiversity and generated some income through the wages they earned as field assistants. Exposure to use of binoculars and bird ringing. I assessed the existing local community groups as potential Site Support Groups (SSG) as they are termed in the Important Bird Areas framework. 2. The project offered a learning opportunity for two graduate interns in the Ornithology Department of National Museums of Kenya. They gained skills in bird survey methods and ringing and use of various equipments. 3. The project has led to immense filling up of knowledge gaps in this area, many birds were not known to occur in this area. Since survey has documented 5 Globally threatened bird species, discussions are under way to recognize as the area as an Important Bird Area (IBA). This is through BirdLife International and National Partner Nature Kenya. 4. For future monitoring a total of 363 individual birds in 35 species were ringed. These include resident, Afro-tropical and Palaearctic migratory species. 5.

It comprises Boni and Dodori National Reserves, Boni- Lungi and Boni-Ijara forests (which at the time of publication were understood to have recently been gazetted as Forest Reserves) and the Aweer Community Conservancy, proposed by the indigenous Aweer (Boni) people and the Northern Rangelands Trust. The Boni-Dodori area was designated Kenya’s 63rd Important Bird and Biodiversity Area (IBA) by Nature Kenya and BirdLife International in 2014. It forms part of the East African coastal forests biodiversity hotspot, an area known for globally significant levels of species richness and one of Africa’s centers of endemism. At the time of going to press, the area was under the control of the Kenya Defence Forces with restricted movement of the public. It is hoped that security will soon be restored and this remarkable landscape will be open to visitors again. This Checklist will be the first guide for visitors. The Landscape The Boni-Dodori forest system is a vast mosaic of east African coastal forest and thicket, seasonally flooded grassland and palm savanna, scattered wetlands and a strip of Acacia woodland.
