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.

  • Namibia & the Okavango
    Southern White-faced Owl gave wonderful views. What a special owl! (JM) NAMIBIA & THE OKAVANGO 23 SEPTEMBER – 8 OCTOBER 2019 LEADERS: STEVE BRAINE and JULIEN MAZENAUER The 2019 Birdquest tour to Namibia & The Okavango continued on a long run of successful trips, despite the extreme drought Southern Africa is experiencing at the moment, resulting in the lack of many usually common migrants like Cuckoos and Warblers. Anyway, we managed to get good views at all the endemics and possible near-endemics of the area. We manage to record 379 species, a good tally given the severe drought. The first day at Windhoek produced many of our first near-endemics like Bradfield’s Swift, Short- toed Rock Thrushes, Violet-eared Waxbills, Rosy-faced Lovebirds, South African Shelducks and many more. Moving on the Spreetshoogte, we gained great views of the sought-after Herero Chat, followed by Layard’s Warbler and Verreaux’s Eagle. The Namib specials were on the show, with repeated sightings of Rüppell’s Korhaans, Gray’s and Stark’s Larks, Red-headed Finches. Dune Lark showed exceptionally well near Rostock Ritz, and our stay at Walvis Bay was highlighted by thousands of waders including 1500 Chestnut- banded Plovers, hundreds of White-fronted Plovers, 15 Damara Terns, a surprising African Penguin and a 1 BirdQuest Tour Report : Namibia & The Okavango 2019 www.birdquest-tours.com Northern Giant Petrel as write-in.

Windhoek has a population of about 300,000, out of Namibia’s tiny population of only 2.1 million, remarkable for a country that is twice the size of California. Crimson-breasted Gonolek (left), the national bird of Namibia, showed well at Avis Dam. On our morning walk at Avis Dam, we enjoyed Marico Sunbird (bottom left) and Southern Cordonbleu (top right), while there were a bounty of waterbirds at the Gammons Water Care (Sewage!) Works, including African Darter (bottom right) and Red-knobbed Coot (top left). Our day in Windhoek was relaxing but still productive. From Windhoek, in the central mountains, we descended into the Namib Desert, where species like these Common Ostrich survive despite incredibly harsh conditions. South African Ground Squirrel (top); Namib Dune Ant (bottom right); and Rueppell’s Bustard (bottom left), creatures of the Namib.

Abstract A parasitological survey was carried out between February and October, 2015 to determine the helminth fauna of the lizard, Agama agama from two locations Ibadan and Ile-Ife, Southwest Nigeria. A total of 133 specimens were collected and examined for helminth infections. The results showed that the overall prevalence of helminth infection in A. agama was 100%. Five species of helminths were recovered comprising three nematodes, Strongyluris brevicaudata (92.5%), Parapharyngodon sp. (89.5%) and unidentified nematode (0.8%), one species of cestode, Oochoristica truncata (56.4%) and one species of trematode, Mesocoelium monas (1.5%).

In the course of recent taxonomic studies in the African Agamidae the West African species were examined and new species have been identified. In this publication a new species of the genus Agama Daudin, 1802 is described from Cameroon and Gabon. Males of the new species differ from all other known Agama in the unique combination of the reticulate colouration of the throat and the blue tip of tail. It is compared with the other Cameroonian members of the genus and several other Agama species from Africa. Additionally, the status of Agama mehelyi Tornier, 1902, only known from its holotype, is discussed. Key words.

This certainly bore fruit on the pre-tour - with larger numbers of migratory shorebirds and terns on the coast, and also during the main tour where we had excellent sightings of a number of intra-African migrants including groups of Southern Carmine Bee-eaters in vivid breeding dress, and also a calling Black Cuckoo at Nxamaseri Lodge. Apart from the coastal section, the areas we visited had experienced good rains during the previous summer, and veld conditions were generally good throughout the main tour. Water flow in the Zambezi River was also considerably higher than during last year’s tour, and the Victoria Falls were spectacular – particularly when contrasted with the isolated trickles we witnessed last year.

Namibia is a fascinating country of flats, hills and mountains with constantly changing habitats. These unique habitats that have given a home to diverse wildlife that can easily be overlooked while wandering around. These include a couple of perfectly camouflaged reptiles, endemics like the reddish Dune Lark, the long-legged Tenobriodis beetles with legs made for handling this dry and hot part of the world. We searched for birds and other wildlife from the plains, dry flatlands and dunes, along with life-supporting sandy rivers, the incomparable game-filled Etosha National Park. and the wooded sand-lands of Botswana. August is not the time of the year to expect rains, but the country is filled with wildlife that has adapted to this dry climate. It also has very welcoming people and some of the most panoramic views of the region. It is a destination with perfect backgrounds for photography, great for casual as well as hardcore photographers, and these shots help enjoying the beautiful memories that will linger. www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report Namibia & Botswana, Aug-Sept 2019 Red-backed-Scrub-Robin Day 1 - August 22, 2019: Arrival to Walvis Bay With Emma, we had arrived in Namibia the previous day and spent a night in Windhoek the country's Capital.
