  • 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.

  • Tanzania 16 - 27 April 2018 Tour Leader Tertius Gous Photographs by Tertius Gous Taken on This Tour
    Tanzania 16 - 27 April 2018 Tour Leader Tertius Gous Photographs by Tertius Gous taken on this tour www.birdingafrica.com Day 0: The first day was spent birding and relaxing at our lodge near Kilimanjaro International Airport while we waited for everyone to arrive. The open Acacia savanna surrounding the lodge always provides a very productive start to the tour and notable sightings included Speckled and Blue- naped Mousebird, White-browed Coucal, Mourning Collared Dove, Little and African Palm Swift, European Roller, Grey-headed Kingfisher, African Hoopoe, Red-backed Shrike, Long-tailed Fiscal, Dark-capped Bulbul (the first of many!), Northern and Red-faced Crombec, Willow Warbler, Eastern Olivaceous Warbler, Tawny-flanked Prinia, Buff-bellied Warbler, Garden Warbler, Winding Cisticola, Spotted Flycatcher, Spotted Palm Thrush, Superb and Violet-backed Starling, Scarlet- chested and Variable Sunbird, Red-billed Firefinch, Blue-capped Cordon-bleu, Crimson-rumped Waxbill and Reichenow’s Seedeater, while Yellow-winged Bat showed well at the lodge. As a bonus, our lodge was perfectly situated for spectacular views of Mount Kilimanjaro, Africa's highest mountain and the highest free-standing mountain in the world. Days 1- 2: We spent two full days exploring the grasslands, lakes, woodlands and forests of Arusha National Park. Close to the entrance of the Park we found a breeding colony of Taveta Weavers supported by a few Golden-backed Weavers and an obliging Brown-breasted Barbet. Soon after we entered the Park an open grassy meadow produced good numbers of African Buffalo with numerous Red- billed Oxpeckers in attendance, as well as Bushbuck. Other mammals found in the grasslands and woodlands included Common Zebra, Giraffe, Warthog, Waterbuck, Kirk’s Dik-dik and numerous troops of Olive Baboons, while the forests held Harvey’s Duiker and the diminutive Suni.

    South Africa Mega Birding Tour I 6th to 30th January 2018 (25 days) Trip Report Aardvark by Mike Bacon Trip report compiled by Tour Leader: Wayne Jones Rockjumper Birding Tours View more tours to South Africa Trip Report – RBT South Africa - Mega I 2018 2 Tour Summary The beauty of South Africa lies in its richness of habitats, from the coastal forests in the east, through subalpine mountain ranges and the arid Karoo to fynbos in the south. We explored all of these and more during our 25-day adventure across the country. Highlights were many and included Orange River Francolin, thousands of Cape Gannets, multiple Secretarybirds, stunning Knysna Turaco, Ground Woodpecker, Botha’s Lark, Bush Blackcap, Cape Parrot, Aardvark, Aardwolf, Caracal, Oribi and Giant Bullfrog, along with spectacular scenery, great food and excellent accommodation throughout. ___________________________________________________________________________________ Despite havoc-wreaking weather that delayed flights on the other side of the world, everyone managed to arrive (just!) in South Africa for the start of our keenly-awaited tour. We began our 25-day cross-country exploration with a drive along Zaagkuildrift Road. This unassuming stretch of dirt road is well-known in local birding circles and can offer up a wide range of species thanks to its variety of habitats – which include open grassland, acacia woodland, wetlands and a seasonal floodplain.

  • Namibia & the Okavango
    Pel’s Fishing Owl - a pair was found on a wooded island south of Shakawe (Jan-Ake Alvarsson) NAMIBIA & THE OKAVANGO 21 SEPTEMBER – 8 OCTOBER 2017 LEADER: STEVE BRAINE For most of the country the previous three years drought had been broken and although too early for the mi- grants we did however do very well with birding generally. We searched and found all the near endemics as well as the endemic Dune Lark. Besides these we also had a new write-in for the trip! In the floodplains after observing a wonderful Pel’s Fishing Owl we travelled down a side channel of the Okavango River to look for Pygmy Geese, we were lucky and came across several pairs before reaching a dried-out floodplain. Four birds flew out of the reedbeds and looked rather different to the normal weavers of which there were many, a closer look at the two remaining birds revealed a beautiful pair of Cuckoo Finches. These we all enjoyed for a brief period before they followed the other birds which had now disappeared into the reedbeds. Very strong winds on three of the birding days made birding a huge challenge to say the least after not finding the rare and difficult Herero Chat we had to make alternate arrangements at another locality later in the trip. The entire tour from the Hosea Kutako International Airport outside the capital Windhoek and returning there nineteen days later delivered 375 species. Out of these, four birds were seen only by the leader, a further three species were heard but not seen.

  • ETHIOPIA: Birding the Roof of Africa; with Southern Extension a Tropical Birding Set Departure
    ETHIOPIA: Birding the Roof of Africa; with Southern Extension A Tropical Birding Set Departure February 7 – March 1, 2010 Guide: Ken Behrens All photos taken by Ken Behrens during this trip ORIENTATION I have chosen to use a different format for this trip report. First, comes a general introduction to Ethiopia. The text of this section is largely drawn from the recently published Birding Ethiopia, authored by Keith Barnes, Christian, Boix and I. For more information on the book, check out http://www.lynxeds.com/product/birding-ethiopia. After the country introduction comes a summary of the highlights of this tour. Next comes a day-by-day itinerary. Finally, there is an annotated bird list and a mammal list. ETHIOPIA INTRODUCTION Many people imagine Ethiopia as a flat, famine- ridden desert, but this is far from the case. Ethiopia is remarkably diverse, and unexpectedly lush. This is the ʻroof of Africaʼ, holding the continentʼs largest and most contiguous mountain ranges, and some of its tallest peaks. Cleaving the mountains is the Great Rift Valley, which is dotted with beautiful lakes. Towards the borders of the country lie stretches of dry scrub that are more like the desert most people imagine. But even in this arid savanna, diversity is high, and the desert explodes into verdure during the rainy season. The diversity of Ethiopiaʼs landscapes supports a parallel diversity of birds and other wildlife, and although birds are the focus of our tour, there is much more to the country. Ethiopia is the only country in Africa that was never systematically colonized, and Rueppell’s Robin-Chat, a bird of the Ethiopian mountains.

  • Bird Survey of South-Eastern Laikipia: Lolldaiga Ranch, Ole Naishu Ranch, Borana Ranch, and Mukogodo Forest Reserve
    8 November 2015 Dear All, Recently Nigel Hunter and I went to stay with Tom Butynski on Lolldaiga Hills Ranch. Whilst there we were joined by Paul Benson, and Eleanor Monbiot for the 31st Oct, Chris Thouless joined us on 1st Nov in Mukogodo, and he and Caroline kindly put the three of us up at their house for the nights of 31st Oct and 1st Nov., and for both these dates we enjoyed the company of Lawrence, the bird-guide at Borana Lodge. For our full day on Lolldaiga on 2nd Nov., Paul spent the entire day with us. The more interesting observations follow, but this is far from the full list which exceeded 200 on Lolldaiga alone in spite of the relatively short time we were there. Best for now Brian BIRD SURVEY OF SOUTH-EASTERN LAIKIPIA: LOLLDAIGA RANCH, OLE NAISHU RANCH, BORANA RANCH, AND MUKOGODO FOREST RESERVE ITINERARY 30th Oct 2015 Drove Nairobi to Lolldaiga, birded as far as old Maize Paddock in late afternoon. 31st Oct Drove from TB house out through Ole Naishu Ranch and across Borana arriving at Mukogodo Forest in early afternoon. 1st Nov All day in Mukogodo Forest, and just 5 kilometres down the main descent road in afternoon. 2nd Nov All day on Borana, back across Ole Naishu to Lolldaiga. 3rd Nov All day outing on Lolldaiga to Black Rock, Ngainitu Kopje (North Gate), Sinyai Lugga, and evening near the Monument. 4th Nov Morning on descent road to Main Gate, Lolldaiga and forest along Timau River, leaving 11.15 AM for Nairobi.

  • South Africa Mega Birding III 5Th to 27Th October 2019 (23 Days) Trip Report
    South Africa Mega Birding III 5th to 27th October 2019 (23 days) Trip Report The near-endemic Gorgeous Bushshrike by Daniel Keith Danckwerts Tour leader: Daniel Keith Danckwerts Trip Report – RBT South Africa – Mega Birding III 2019 2 Tour Summary South Africa supports the highest number of endemic species of any African country and is therefore of obvious appeal to birders. This South Africa mega tour covered virtually the entire country in little over a month – amounting to an estimated 10 000km – and targeted every single endemic and near-endemic species! We were successful in finding virtually all of the targets and some of our highlights included a pair of mythical Hottentot Buttonquails, the critically endangered Rudd’s Lark, both Cape, and Drakensburg Rockjumpers, Orange-breasted Sunbird, Pink-throated Twinspot, Southern Tchagra, the scarce Knysna Woodpecker, both Northern and Southern Black Korhaans, and Bush Blackcap. We additionally enjoyed better-than-ever sightings of the tricky Barratt’s Warbler, aptly named Gorgeous Bushshrike, Crested Guineafowl, and Eastern Nicator to just name a few. Any trip to South Africa would be incomplete without mammals and our tally of 60 species included such difficult animals as the Aardvark, Aardwolf, Southern African Hedgehog, Bat-eared Fox, Smith’s Red Rock Hare and both Sable and Roan Antelopes. This really was a trip like no other! ____________________________________________________________________________________ Tour in Detail Our first full day of the tour began with a short walk through the gardens of our quaint guesthouse in Johannesburg. Here we enjoyed sightings of the delightful Red-headed Finch, small numbers of Southern Red Bishops including several males that were busy moulting into their summer breeding plumage, the near-endemic Karoo Thrush, Cape White-eye, Grey-headed Gull, Hadada Ibis, Southern Masked Weaver, Speckled Mousebird, African Palm Swift and the Laughing, Ring-necked and Red-eyed Doves.

    INTAKE AND GROWTH RATES OF THREE PASSERINE SPECIES AT DISNEY’S ANIMAL KINGDOM Shannon Livingston, MSc,1 Eduardo Valdes, PhD1,2,3,4 Paul Schutz1 1 Disney’s Animal Kingdom, Bay Lake FL 2 University of Florida, Dept. Animal Sciences, Gainesville FL 3 University of Central Florida, Orlando FL 4 University of Guelph, Dept. Animal Sciences, Guelph ON Whenever possible, avian parents are tasked with raising their young. Occasionally circumstances dictate that young are pulled for hand rearing. Protocols are in place for different species that indicate food items and amounts to feed as well as developmental indicators and husbandry parameters. Avian species have different diets as adults but many utilize similar food items to feed their young. Here we compare the nutrient intake and growth rates of hand reared Taveta Golden Weavers (Ploceus castaneiceps), White Headed Buffalo Weavers (Dinemellia dinemelli) and Magpie Shrikes (Corvinella melanoleuca) at Disney’s Animal Kingdom. All three species are native to Africa, although there is minimal overlap of their natural distribution. The white headed buffalo weaver is native to savannah and dry brush in East Africa and has an adult diet of seeds, fruits, and insects. The taveta golden weaver lives in woodland and swampy areas of part of Kenya and Tanzania and has an adult diet consisting mainly of seeds. The magpie shrike lives in parts of Eastern and Southern Africa and has an adult diet consisting mainly of arthropods and other insects, lizards, rodents, carrion and fruit. At Disney’s Animal Kingdom, the birds are housed in mixed species aviaries. Specific food items are designated for the different species, although the birds have access to, and are often seen feeding from, a variety of food options.

  • Zimbabwe & Botswana TRIP REPORT Nov 2017 Summary
    ZIMBABWE & BOTSWANA WILDLIFE SAFARI November 3-15, 2017 TRIP REPORT Summary by Adrian Binns Mana Pools, Zimbabwe Our 12-day African safari began on the eastern edge of Mana Pools National Park in northern Zimbabwe. From our bush camps at Ruckomechi and neighbouring Little Ruckomechi, we enjoyed exploring a range of habitats teeming with wonderful wildlife. Elephants were among the first to greet us, as they roamed freely near the tents, even venturing next to the swimming pool! We kept a watchful eye and careful distance, in awe of the giant pachyderms. What a welcome treat! Our camps overlooked the mighty Zambezi river towards Zambia’s Rift Valley escarpment, providing excellent opportunity for relaxing afternoon boat rides. We drifted slowly up to wallowing pods of hippos, basking crocodiles, and African Skimmers loafing on exposed narrow sand strips. In steeply-eroded river banks, White- fronted and Southern Carmine Bee-eaters excavated their tunnel nests. The location helps keep predators at bay, but not all of them! On two consecutive afternoons we watched a Nile Water Monitor dig into the tunnels with its long sharp claws, and come out with a youngster, much to the chagrin of the parents. We watched elephants trek through tall grasses of river islands, and cross channels to reach the opposite bank. We cheered when one struggling baby elephant finally made it across. One evening we were moored on a riverbank enjoying sundowners, when an inquisitive elephant approached to within feet of Jane who was seated at the front of the boat. It was a heart-stopping moment to be face-to-face with such a huge animal – so close we could count the eyelashes – but we had nowhere to go.

  • The Best of SOUTH AFRICA October 15-31 2018
    TRIP REPORT: The Best of SOUTH AFRICA October 15-31 2018 The Best of SOUTH AFRICA Birding Safari October 15-31, 2018 Tour leaders: Josh Engel and David Nkosi Click here for the trip photo gallery Next trip: October 10-26, 2020 South Africa never fails to amaze. From the spectacular scenery and endemic birds of the Cape to the megafauna-filled wilderness of Kruger National Park, every single day brings something new, surprising, and awe-inspiring. This trip exceeded expectations—over 400 species of birds and an incredible 60 species of mammals, all seen while staying in interesting, varied, and excellent accommodations, eating delicious food, and thoroughly enjoying all aspects of traveling in South Africa. It’s hard to know where to start with bird and animal highlights. There are, of course, the most sought-after birds, like Protea Canary, Cape Rockjumper, Black Harrier, Rudd’s Lark, Black-eared Sparrowlark, Southern Black Korhaan, and Blue Korhaan. There were also the incredible bird experiences—the Shy Albatrosses surrounding our pelagic boat, the Cape Sugarbird singing from atop of king protea flower, the nest-building Knysna Turacos, the Water Thick-knees trying to chase a Water Monitor away from their nest. Mammals take a front seat in South Africa, too. We had incredible sightings of Leopard and Lion in Kruger, numerous White and a single Black Rhinoceros, along with many encounters with Elephant, Giraffes, and other iconic African animals. But we also saw many awesome small mammals, including Meerkat, Large- and Small- spotted Genet, White-tailed Mongoose, and a Cape Clawless Otter munching on a fish.
