SINGITA SABI SAND, SOUTH AFRICA for the Month of December, Two Thousand and Fifteen
WILDLIFE REPORT SINGITA SABI SAND, SOUTH AFRICA For the month of December, Two Thousand and Fifteen Temperature Rainfall Recorded Sunrise & Sunset Average minimum: 22˚C (71.6˚F) For the month: 36 mm Sunrise 05:05 Average maximum: 34.2˚C (93.6˚F) For the year to date: 286 mm Sunset 18:46 Minimum recorded: 18◦C (64.4˚F) For the season to date: 173.2 mm Maximum recorded: 41˚C (105.8˚F) With a maximum record of 41˚C, the vegetation has been scorched by the hot conditions. Fortunately with the light rain that we did receive it’s allowed some of the flowering plants to blossom. Here's a highlights package of the month's sightings: Hyenas: It's such a joy when hyena cubs are about - they're curios and like to investigate everything around them. Lions: Lion sightings currently could not get any better! Two male lions of the Matimba coalition have been sighted on a few occasions, and they are gradually expanding their current territorial zone north of the river. The Mhangene pride continue to dominate the central area of Singita Sabi Sand. We watched a few interactions between the Majingalane male lions and the sub-adult males of the Mhangene pride that resulted in the young males being dispersed from the pride temporarily. One of the lionesses from the Mhangene pride has been seen with prominent suckle marks indicating that she has given birth. The lionesses has been seen moving in front of the lodges during the early morning and we suspect that the cubs are hidden in the river just east of Boulders Lodge. -
WILDLIFE JOURNAL SINGITA GRUMETI, TANZANIA for the Month of April, Two Thousand and Nineteen
Photo by George Tolchard WILDLIFE JOURNAL SINGITA GRUMETI, TANZANIA For the month of April, Two Thousand and Nineteen Temperature Rainfall Recorded Sunrise & Sunset Average minimum: 19°C Faru Faru 47 mm Sunrise 06:40 Average maximum: 29°C Sabora 53 mm Sunset 18:40 Minimum recorded: 17°C Sasakwa 162 mm Maximum recorded: 34.3°C April has been another lovely month, packed full of exciting moments and incredible wildlife viewing. April is usually an incredibly wet month for us here in northern Tanzania, however this year we have definitely received less rain than in years gone by. Only at the end of the month have we seen a noticeable change in the weather and experienced our first heavy downpours. Thankfully there seems to have been just enough to keep the grasses looking green and although the heavy rains have arrived late, an encouraging green flush is spreading across the grasslands. Resident herds of topi, zebra, buffalo, Thompson’s gazelle, eland, Grant’s gazelle and impala are flourishing as usual and have remained as a great presence especially out on the Nyati Plain and the Nyasirori high ground. Reports of the migratory wildebeest were received towards the end of the month, and on the 27th we glanced from the top of Sasakwa Hill to see mega-herds of wildebeest, to the south of our border with the National Park, streaming onto the grasslands at the base of the Simiti Hills. We sit in anticipation and wonder where the great herds will move next. Cat sightings have been great this month, again, despite the long seeding grasses. -
Eagle Hill, Kenya: Changes Over 60 Years
Scopus 34: 24–30, January 2015 Eagle Hill, Kenya: changes over 60 years Simon Thomsett Summary Eagle Hill, the study site of the late Leslie Brown, was first surveyed over 60 years ago in 1948. The demise of its eagle population was near-complete less than 50 years later, but significantly, the majority of these losses occurred in the space of a few years in the late 1970s. Unfortunately, human densities and land use changes are poor- ly known, and thus poor correlation can be made between that and eagle declines. Tolerant local attitudes and land use practices certainly played a significant role in protecting the eagles while human populations began to grow. But at a certain point it would seem that changed human attitudes and population density quickly tipped the balance against eagles. Introduction Raptors are useful in qualifying habitat and biodiversity health as they occupy high trophic levels (Sergio et al. 2005), and changes in their density reflect changes in the trophic levels that support them. In Africa, we know that raptors occur in greater diversity and abundance in protected areas such as the Matapos Hills, Zimbabwe (Macdonald & Gargett 1984; Hartley 1993, 1996, 2002 a & b), and Sabi Sand Reserve, South Africa (Simmons 1994). Although critically important, few draw a direct cor- relation between human effects on the environment and raptor diversity and density. The variables to consider are numerous and the conclusions unworkable due to dif- ferent holding-capacities, latitude, land fertility, seasonality, human attitudes, and different tolerances among raptor species to human disturbance. Although the concept of environmental effects caused by humans leading to rap- tor decline is attractive and is used to justify raptor conservation, there is a need for caution in qualifying habitat ‘health’ in association with the quantity of its raptor community. -
Dendroaspis Viridis
Dendroaspis viridis The western green mamba (Dendroaspis viridis), also known as the West African green mamba or Hallowell's green mamba, is a long, thin, and highly venomous snake of the mamba genus, Dendroaspis. This species was first described in 1844 by the American herpetologist Edward Hallowell. The western green mamba is a fairly large and predominantly arboreal species, capable of navigating through trees swiftly and gracefully. It will also descend to ground level to pursue prey such as rodents and other small mammals. The western green mamba is a very alert, nervous, and extremely agile snake that lives mainly in the coastal tropical rainforest, thicket, Scientific Classification and woodland regions of western Africa. Like all the other mambas, the western green mamba is a highly venomous elapid species. Its Kingdom: Anamalia venom is a highly potent mixture of rapid-acting presynaptic and Phylum: Cordata postsynaptic neurotoxins (dendrotoxins), cardiotoxins and fasciculins. Class: Reptilia Some consider this species to not be a particularly aggressive snake, Order: Squamata but others have suggested that they are extremely nervous and are Suborder: Serpentes prone to attack aggressively when cornered. Conflict with humans is Family: Elapidae low compared to some other species found in the region. Bites to Geunus Dendroaspis people by this species are quite uncommon. Their mortality rate, Species D.Viridis however, is high; many of the recorded bites have been fatal. Rapid progression of severe, life-threatening symptoms are hallmarks of Binomial Name mamba bites. Bites with envenomation can be rapidly fatal. Dendroaspis viridis (Hallowell, 1844)[2] Taxonomy Dendroaspis viridis was first described by the American herpetologist and physician Edward Hallowell in 1844.[2][5] In addition to being called the western green mamba, this species is also commonly known as [6] the West African green mamba or Hallowell's green mamba. -
A Multi-Gene Phylogeny of Aquiline Eagles (Aves: Accipitriformes) Reveals Extensive Paraphyly at the Genus Level

Helbig'^*, Annett Kocum'^, Ingrid Seibold^, Michael J. Braun^ '^ Institute of Zoology, University of Greifswald, Vogelwarte Hiddensee, D-18565 Kloster, Germany Department of Zoology, National Museum of Natural History, Smithsonian Institution, 4210 Silver Hill Rd., Suitland, MD 20746, USA Received 19 March 2004; revised 21 September 2004 Available online 24 December 2004 Abstract The phylogeny of the tribe Aquilini (eagles with fully feathered tarsi) was investigated using 4.2 kb of DNA sequence of one mito- chondrial (cyt b) and three nuclear loci (RAG-1 coding region, LDH intron 3, and adenylate-kinase intron 5). Phylogenetic signal was highly congruent and complementary between mtDNA and nuclear genes. In addition to single-nucleotide variation, shared deletions in nuclear introns supported one basal and two peripheral clades within the Aquilini. Monophyly of the Aquilini relative to other birds of prey was confirmed. However, all polytypic genera within the tribe, Spizaetus, Aquila, Hieraaetus, turned out to be non-monophyletic. Old World Spizaetus and Stephanoaetus together appear to be the sister group of the rest of the Aquilini. Spiza- stur melanoleucus and Oroaetus isidori axe nested among the New World Spizaetus species and should be merged with that genus. The Old World 'Spizaetus' species should be assigned to the genus Nisaetus (Hodgson, 1836). The sister species of the two spotted eagles (Aquila clanga and Aquila pomarina) is the African Long-crested Eagle (Lophaetus occipitalis). -
South Africa: Magoebaskloof and Kruger National Park Custom Tour Trip Report
SOUTH AFRICA: MAGOEBASKLOOF AND KRUGER NATIONAL PARK CUSTOM TOUR TRIP REPORT 24 February – 2 March 2019 By Jason Boyce This Verreaux’s Eagle-Owl showed nicely one late afternoon, puffing up his throat and neck when calling www.birdingecotours.com [email protected] 2 | TRIP REPORT South Africa: Magoebaskloof and Kruger National Park February 2019 Overview It’s common knowledge that South Africa has very much to offer as a birding destination, and the memory of this trip echoes those sentiments. With an itinerary set in one of South Africa’s premier birding provinces, the Limpopo Province, we were getting ready for a birding extravaganza. The forests of Magoebaskloof would be our first stop, spending a day and a half in the area and targeting forest special after forest special as well as tricky range-restricted species such as Short-clawed Lark and Gurney’s Sugarbird. Afterwards we would descend the eastern escarpment and head into Kruger National Park, where we would make our way to the northern sections. These included Punda Maria, Pafuri, and the Makuleke Concession – a mouthwatering birding itinerary that was sure to deliver. A pair of Woodland Kingfishers in the fever tree forest along the Limpopo River Detailed Report Day 1, 24th February 2019 – Transfer to Magoebaskloof We set out from Johannesburg after breakfast on a clear Sunday morning. The drive to Polokwane took us just over three hours. A number of birds along the way started our trip list; these included Hadada Ibis, Yellow-billed Kite, Southern Black Flycatcher, Village Weaver, and a few brilliant European Bee-eaters. -
The Martial Eagle Terror of the African Bush
SCOOP! 4 THE MARTIAL EAGLE TERROR OF THE AFRICAN BUSH The martial eagle is a A CLOSE ENCOUNTER WITH A NEAR-LEGENDARY very large eagle. In total AND SEVERELY THREATENED PREDATOR length, it can range from 78 to 96 cm (31 to 38 in), with a wingspan from 188 to 260 cm (6 ft 2 in to 8 ft 6 in). 5 The martial eagle is one of the world's most powerful avian predators. Prey may vary considerably in size but for the most part, prey weighing less than 0.5 kg (1.1 lb) are ignored, with the average size of prey being between 1 and 5 kg (2.2 and 11.0 lb). TEXT BY ANDREA FERRARI PHOTOS BY ANDREA & ANTONELLA FERRARI uring a lifetime of explorations we have met and mammals, large birds and reptiles. An inhabitant of occasion - while it was gorging itself on a fresh duck or photographed the huge, intimidating martial eagle wooded belts of otherwise open savanna, this species has goose kill by a waterhole in Etosha NP, Namibia - was PolemaetusD bellicosus quite a few times - despite being sadly shown a precipitous decline in the last few centuries rather special. Luckily most martial eagles don’t seem too currently severely threatened and not really common due to a variety of factors as it is one of the most persecuted shy when feasting (if properly approached, of course - we anywhere, it still is relatively easy observing one in the bird species in the world. Due to its habit of taking livestock had already photographed another eating a mongoose in African plains. -

Kenyan Birding & Animal Safari Organized by Detroit Audubon and Silent Fliers of Kenya July 8Th to July 23Rd, 2019
Kenyan Birding & Animal Safari Organized by Detroit Audubon and Silent Fliers of Kenya July 8th to July 23rd, 2019 Kenya is a global biodiversity “hotspot”; however, it is not only famous for extraordinary viewing of charismatic megafauna (like elephants, lions, rhinos, hippos, cheetahs, leopards, giraffes, etc.), but it is also world-renowned as a bird watcher’s paradise. Located in the Rift Valley of East Africa, Kenya hosts 1054 species of birds--60% of the entire African birdlife--which are distributed in the most varied of habitats, ranging from tropical savannah and dry volcanic- shaped valleys to freshwater and brackish lakes to montane and rain forests. When added to the amazing bird life, the beauty of the volcanic and lava- sculpted landscapes in combination with the incredible concentration of iconic megafauna, the experience is truly breathtaking--that the Africa of movies (“Out of Africa”), books (“Born Free”) and documentaries (“For the Love of Elephants”) is right here in East Africa’s Great Rift Valley with its unparalleled diversity of iconic wildlife and equatorially-located ecosystems. Kenya is truly the destination of choice for the birdwatcher and naturalist. Karibu (“Welcome to”) Kenya! 1 Itinerary: Day 1: Arrival in Nairobi. Our guide will meet you at the airport and transfer you to your hotel. Overnight stay in Nairobi. Day 2: After an early breakfast, we will embark on a full day exploration of Nairobi National Park--Kenya’s first National Park. This “urban park,” located adjacent to one of Africa’s most populous cities, allows for the possibility of seeing the following species of birds; Olivaceous and Willow Warbler, African Water Rail, Wood Sandpiper, Great Egret, Red-backed and Lesser Grey Shrike, Rosy-breasted and Pangani Longclaw, Yellow-crowned Bishop, Jackson’s Widowbird, Saddle-billed Stork, Cardinal Quelea, Black-crowned Night- heron, Martial Eagle and several species of Cisticolas, in addition to many other unique species. -

They have an African wide distribution with the exception of forests and true deserts. Approximately 600 pairs are suggested to occupy a range across South Africa (Taylor, 2015). The species is long lived (Paijmans, 2016), reaches sexually maturity at 6 years old and has a low fecundity fledging on average on ce chick every second year (Steyn, 1982). Martial Eagles are a low-density species with large home ranges; inter-nest distances average ca. 12 km (Tarboton and Allan, 1984). These extreme k-selected life history traits and small population sizes predispose the species to occupy relatively stable environments with low unnatural mortalities.
