“…The deteriorating conservation status of the Egyptian Vulture seems primarily linked to incidental mortality from feeding on poisonous baits or deliberately poisoned carcasses to control mammals regarded as pests (Iñigo et al 2008;Hille and Collar 2011;Virani et al 2011). Therefore, the widespread practice of mass poisoning of stray dogs in the Afar region, and Ethiopia as a whole (Yilma 2013), should be strictly prohibited and replaced by alternative methods allowing efficient control of the stray dogs numbers and spread of epidemics, e.g.…”

The Endangered Egyptian Vulture Neophron percnopterus congregates in communal roosts in the wintering areas and where food availability is high, where even a single threat might lead to substantial population declines. Thus, more research on the congregation sites is needed for timely detection of threats and effectively directed conservation measures. We studied bird numbers, use of roosting substrates and roosting habitat of wintering Egyptian Vultures in Ethiopia. Vultures were counted using the road-count technique in 2009, 2010 and 2013 along c. 600 km of roads in the Afar region. Over 1 000 individuals were counted each year and the sites with the highest congregations were identified. Nearly half of the birds were adults and the majority roosted on bird-safe types of electric pylons. Most of the Egyptian Vultures were found below 500 m above sea level, in bare areas, open savannas or grasslands, and their abundance was negatively related to the amount of cover of bush vegetation. The distribution of roosting birds was not affected by distance to human settlements. To avoid disasterous effects on the population of the Egyptian Vultures, we strongly recommend that the sites sheltering the highest numbers of roosting birds should be included in the Important Bird Area network, the use of poisons should be banned, and dangerous power lines should be insulated or substituted with safer types.

“…species has exhibited declines across much of its range, from 50% to 90% in different regions (Nikolaus 2006, Thiollay 2006, Virani et al, 2011, Ogada et al 2015. Due to this situation, the global conservation category of this vulture has been decreased to Endangered (IUCN, 2014).…”

“…The birds of the Mara-Serengeti ecosystem have received less attention, however basic species lists are available for the region, and some ecological studies have also been conducted (e.g. Sinclair et al 2002, Virani et al 2011. The avifauna of the Greater Mara Region is relatively well known in the Masai Mara National Reserve but is poorly known beyond its boundaries in the conservancies to the north of the reserve.…”

Habitat associations of birds were quantified through fixed-radius timed bird counts at Mara Naboisho Conservancy within the Greater Mara Region, Kenya. We conducted 73 timed counts in four distinct habitats (riparian, woodland, rocky outcrop and plains) in both dry and wet seasons. During this survey, we observed 188 species of birds of which 140 were recorded during the timed counts. The riparian zone had the highest species richness, more than three times that of the plains. The woodlands and rocky outcrops had similar species richness. The mean number of species seen per count was higher in the riparian zone compared with the other three habitats. Bird species composition in the riparian zone and the plains were distinct from each other and from the woodlands and rocky outcrops, although they overlapped significantly in the last two mentioned habitats. The possible conservation implication of an increasing and/or immigrant elephant population and its likely effect on the vegetation is discussed in relation bird community composition.
