Oromia is the largest National Regional State of Ethiopia. Here we present the first comprehensive checklist of its birds. A total of 804 bird species has been recorded, 601 of them confirmed (443) or assumed (158) to be breeding birds. At least 561 are all-year residents (and 31 more potentially so), at least 73 are Afrotropical migrants and visitors (and 44 more potentially so), and 184 are Palaearctic migrants and visitors (and eight more potentially so). Three species are endemic to Oromia, 18 to Ethiopia and 43 to the Horn of Africa. 170 Oromia bird species are biome restricted: 57 to the Afrotropical Highlands biome, 95 to the Somali-Masai biome, and 18 to the Sudan-Guinea Savanna biome. -

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. -

EDITOR: Mrs Ajetomobi School of Agricultural Sciences Lagos State Polytechnic Ikorodu, Lagos 2 BIO 313 COURSE GUIDE Introduction Animal Ecology (313) is a first semester course. It is a two credit unit elective course which all students offering Bachelor of Science (BSc) in Biology can take. Animal ecology is an important area of study for scientists. It is the study of animals and how they related to each other as well as their environment. It can also be defined as the scientific study of interactions that determine the distribution and abundance of organisms. Since this is a course in animal ecology, we will focus on animals, which we will define fairly generally as organisms that can move around during some stages of their life and that must feed on other organisms or their products. There are various forms of animal ecology. This includes: • Behavioral ecology, the study of the behavior of the animals with relation to their environment and others • Population ecology, the study of the effects on the population of these animals • Marine ecology is the scientific study of marine-life habitat, populations, and interactions among organisms and the surrounding environment including their abiotic (non-living physical and chemical factors that affect the ability of organisms to survive and reproduce) and biotic factors (living things or the materials that directly or indirectly affect an organism in its environment). -

AVIAN SAFARIS 23 DAY UGANDA BIRDING AND NATURE TOUR ITINERARY Date: July 7 July 29, 2019 Tour Leader: Crammy Wanyama Trip Report and all photos by Crammy Wanyama Black-headed Gonolek a member of the Bush-shrikes family Day 1 – July 7, 2019: Beginning of the tour This tour had uneven arrivals. Two members arrived two days earlier and the six that came in on the night before July 7th, stayed longer; therefore, we had a pre and post- tour to Mabira Forest. For today, we all teamed up and had lunch at our accommodation for the next two nights. This facility has some of the most beautiful gardens around Entebbe; we decided to spend the rest of the afternoon here watching all the birds you would not expect to find around a city garden. Some fascinating ones like the Black-headed Gonolek nested in the garden, White-browed Robin-Chat too did. The trees that surrounded us offered excellent patching spots for the African Hobby. Here we had a Falco patching out in the open for over forty minutes! Superb looks at a Red-chested and Scarlet-chested Sunbirds. The gardens' birdbath attracted African Thrush that reminded the American birders of their American Robin, Yellow- throated Greenbul. Still looking in the trees, we were able to see African Grey Woodpeckers, both Meyer's and Grey Parrot, a pair of Red-headed Lovebirds. While walking around the facility, we got good looks at a flying Shikra and spent ample time with Ross's Turaco that flew back and forth. We had a very lovely Yellow-fronted Tinkerbird on the power lines, Green-backed Camaroptera, a very well sunlit Avian Safaris: Email: [email protected] Website: http://www.aviansafaris.com AVIAN SAFARIS Spectacled Weaver, was added on the Village and Baglafecht Weavers that we had seen earlier and many more. -

The Herpetofauna of the Cubango, Cuito, and Lower Cuando River Catchments of South-Eastern Angola
Official journal website: Amphibian & Reptile Conservation amphibian-reptile-conservation.org 10(2) [Special Section]: 6–36 (e126). The herpetofauna of the Cubango, Cuito, and lower Cuando river catchments of south-eastern Angola 1,2,*Werner Conradie, 2Roger Bills, and 1,3William R. Branch 1Port Elizabeth Museum (Bayworld), P.O. Box 13147, Humewood 6013, SOUTH AFRICA 2South African Institute for Aquatic Bio- diversity, P/Bag 1015, Grahamstown 6140, SOUTH AFRICA 3Research Associate, Department of Zoology, P O Box 77000, Nelson Mandela Metropolitan University, Port Elizabeth 6031, SOUTH AFRICA Abstract.—Angola’s herpetofauna has been neglected for many years, but recent surveys have revealed unknown diversity and a consequent increase in the number of species recorded for the country. Most historical Angola surveys focused on the north-eastern and south-western parts of the country, with the south-east, now comprising the Kuando-Kubango Province, neglected. To address this gap a series of rapid biodiversity surveys of the upper Cubango-Okavango basin were conducted from 2012‒2015. This report presents the results of these surveys, together with a herpetological checklist of current and historical records for the Angolan drainage of the Cubango, Cuito, and Cuando Rivers. In summary 111 species are known from the region, comprising 38 snakes, 32 lizards, five chelonians, a single crocodile and 34 amphibians. The Cubango is the most western catchment and has the greatest herpetofaunal diversity (54 species). This is a reflection of both its easier access, and thus greatest number of historical records, and also the greater habitat and topographical diversity associated with the rocky headwaters. -
