Abstract Marcot, Bruce G. 1995. Owls of old forests of the world. Gen. Tech. Rep. PNW- GTR-343. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 64 p. A review of literature on habitat associations of owls of the world revealed that about 83 species of owls among 18 genera are known or suspected to be closely asso- ciated with old forests. Old forest is defined as old-growth or undisturbed forests, typically with dense canopies. The 83 owl species include 70 tropical and 13 tem- perate forms. Specific habitat associations have been studied for only 12 species (7 tropical and 5 temperate), whereas about 71 species (63 tropical and 8 temperate) remain mostly unstudied. Some 26 species (31 percent of all owls known or sus- pected to be associated with old forests in the tropics) are entirely or mostly restricted to tropical islands. Threats to old-forest owls, particularly the island forms, include conversion of old upland forests, use of pesticides, loss of riparian gallery forests, and loss of trees with cavities for nests or roosts. Conservation of old-forest owls should include (1) studies and inventories of habitat associations, particularly for little-studied tropical and insular species; (2) protection of specific, existing temperate and tropical old-forest tracts; and (3) studies to determine if reforestation and vege- tation manipulation can restore or maintain habitat conditions. An appendix describes vocalizations of all species of Strix and the related genus Ciccaba. Keywords: Owls, old growth, old-growth forest, late-successional forests, spotted owl, owl calls, owl conservation, tropical forests, literature review. -
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. -
Namibia Crane News 11
Namibia Crane News 11 July 2005 National B lue crane census proposed The Namibia Crane Working Group is investigating a national Blue Crane census, to obtain an update on numbers. This proposal corresponds with the recom- mended actions from the Red Data Book account for Blue Cranes (see Namibia Crane News No. 6). The last count in December 1994 provided a total estimate of 49 adults and 11 yearlings. It will be interesting to see whether the population is still declining after the recent good rains. Ideally the census would include an aerial survey of Etosha and the grassland areas to the north, together with ground surveys. We are still deciding on the best time of year for the census, bearing in mind that we would like to pick up as many juveniles as Enthusiastic Kasika and Impalila guides out birding possible. Any incidental observations of the other two (Photo: Sandra Slater-Jones) crane species would also be noted, but a full census of help bird enthusiasts find Rosy-throated Longclaw, the latter species would probably be more feasible after Black Coucal, Luapula Cisticola, Slaty egret, African the rainy season, when the non-resident Wattled Skimmer, Swamp Boubou, Western Banded Snake Cranes visit the Nyae Nyae pans.

Laniarius Spp.) in Coastal Kenya and Somalia
Brian W. Finch et al. 74 Bull. B.O.C. 2016 136(2) Redefining the taxonomy of the all-black and pied boubous (Laniarius spp.) in coastal Kenya and Somalia by Brian W. Finch, Nigel D. Hunter, Inger Winkelmann, Karla Manzano-Vargas, Peter Njoroge, Jon Fjeldså & M. Thomas P. Gilbert Received 21 October 2015 Summary.—Following the rediscovery of a form of Laniarius on Manda Island, Kenya, which had been treated as a melanistic morph of Tropical Boubou Laniarius aethiopicus for some 70 years, a detailed field study strongly indicated that it was wrongly assigned. Molecular examination proved that it is the same species as L. (aethiopicus) erlangeri, until now considered a Somali endemic, and these populations should take the oldest available name L. nigerrimus. The overall classification of coastal boubous also proved to require revision, and this paper presents a preliminary new classification for taxa in this region using both genetic and morphological data. Genetic evidence revealed that the coastal ally of L. aethiopicus, recently considered specifically as L. sublacteus, comprises two unrelated forms, requiring a future detailed study. The black-and-white boubous—characteristic birds of Africa’s savanna and wooded regions—have been treated as subspecies of the highly polytypic Laniarius ferrugineus (Rand 1960), or subdivided, by separating Southern Boubou L. ferrugineus, Swamp Boubou L. bicolor and Turati’s Boubou L. turatii from the widespread and geographically variable Tropical Boubou L. aethiopicus (Hall & Moreau 1970, Fry et al. 2000, Harris & Franklin 2000). They are generally pied, with black upperparts, white or pale buff underparts, and in most populations a white wing-stripe. -
Secrets of Chimanimani Revealed in Biodiversity Surveys 7 August 2019, by Sarah Pocock
Secrets of Chimanimani revealed in biodiversity surveys 7 August 2019, by Sarah Pocock species. The second, more forested lowland area, did unfortunately show signs of human disturbance and encroachment by an invasive South American plant. Sadly, this forest habitat, found in the Moribane zone, is becoming increasingly rare in Mozambique, with only pockets representing some of the last of its type still left standing. Credit: Millie Kerr/FFI Despite not boasting the fame of the Serengeti or Kruger National Park, Chimanimani, straddling the Mozambican and Zimbabwean border, is an area like no other. Diverse landscapes and unique plant and animal species coexist together in this comparatively unheralded region of southern Africa. Chimanimani’s mountainous landscapes are home to many fascinating species. Credit: Millie Kerr/FFI Botanists hail Chimanimani as a plant hotspot, with previous studies of highland flora revealing exceptionally high levels of endemism, but rather less is known of Chimanimani's animal and Even so, the surveys documented almost 1,100 lowland plant communities; a scientific knowledge species, including some new records for gap existed that needed to be filled.

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. -

Answering the Call of the Thunder Bird
www.forestryexplained.co.za Answering the call of the Thunder Bird Forestry Explained: Our Conservation Legacy South Africa’s thunder bird The Southern Ground-Hornbill (Bucorvus leadbeateri) is an African icon. Its long eyelashes, flash of white primary flight feathers against a backdrop of black and red gular pouch along with its characteristic tiptoe gait make it impossible to confuse with anything else. Known to be the avian world’s largest co-operative breeder, these ground-hornbills live in groups of two to 12, made up of mostly male helpers that help defend the territory and aid the breeding pair with raising their young . Surviving on insects, reptiles, amphibians and small to medium sized birds and mammals , Southern Ground-Hornbills need to defend such large territories in order to find sufficient prey and ensure that within that territory is a suitable nest hollow. The Southern Ground-Hornbill is ecologically important as a top-order predator which has earned it a place in the ‘African Big Six’ of the bird world. It is also culturally important, fondly deemed to be the ‘bringer of rain’. Yet the future of South Africa’s thunder bird has never looked more uncertain. This makes them sparsely distributed over their natural range - which in the 1900’s covered most of Limpopo, Mpumalanga, KwaZulu-Natal, the northern Eastern Cape and even parts of Gauteng. Sadly, this area has shrunk greatly over the past century as habitat has been lost and groups exterminated with devastating effect to their populations. Today only three core concentrations remain: 1. Kruger National Park and adjacent private reserves that make up the greater Kruger region. -
The Birds of the Dar Es Salaam Area, Tanzania
Le Gerfaut, 77 : 205–258 (1987) BIRDS OF THE DAR ES SALAAM AREA, TANZANIA W.G. Harvey and KM. Howell INTRODUCTION Although the birds of other areas in Tanzania have been studied in detail, those of the coast near Dar es Salaam have received relatively little recent attention. Ruggles-Brise (1927) published a popular account of some species from Dar es Salaam, and Fuggles-Couchman (1939,1951, 1953, 1954, 1962) included the area in a series of papers of a wider scope. More recently there have been a few other stu dies dealing with particular localities (Gardiner and Gardiner 1971), habitats (Stuart and van der Willigen 1979; Howell 1981), or with individual species or groups (Harvey 1971–1975; Howell 1973, 1977). Britton (1978, 1981) has docu mented specimens collected in the area previous to 1967 by Anderson and others. The purpose of this paper is to draw together data from published reports, unpu blished records, museum specimens and our own observations on the frequency, habitat, distribution and breeding of the birds of the Dar es Salaam area, here defi ned as the portion of the mainland within a 64-km radius of Dar es Salaam, inclu ding the small islands just offshore (Fig. 1). It includes Dar es Salaam District and portions of two others, Kisarawe and Bagamoyo. Zanzibar has been omitted because its unusual avifauna has been reviewed (Pakenham 1979). Most of the mainland areas are readily accessible from Dar es Salaam by road and the small islands may be reached by boat. The geography of the area is described in Sutton (1970). -
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.

Singita Kruger National Park Wildlife Report August 2013
Singita Kruger National Park Lebombo & Sweni Lodges South Africa Wildlife Journal For the month of July, Two Thousand and Thirteen Temperature Rainfall Recorded Average Minimum: 12.3°C (54.1°F) For the period: 0mm Average Maximum: 27.0°C (80.7°F) For the year to date: 409.5mm Minimum recorded: 02.0°C (35.6°F) Maximum recorded: 34.0°C (93.4°F) Winter is definitely coming to an end Winter is always a productive time of the year for us on the concession, and this year has been as exciting as ever. A combination of the vegetation thinning out, and the permanent water sources have made for some spectacular, and consistent seasonal game viewing. Spring is upon us, and already some of the migratory birds have returned to this their southern destination - like southern yellow-billed kites and Wahlberg’s eagles. We now look forward to the first rains, with the promise of green colours, insect sounds and fresh smells, not to forget it's coming up to baby season! Coming of age It’s a harsh time in every young male lion's life, the day that they are seen as a threat to the dominant male and pushed into independence. When these young males reach puberty they are evicted from the pride and need to fend for themselves, this way ensuring there is no inbreeding within a pride. Pride dynamics dictate that all female members are related, being sisters, cousins or aunts to one another. Male eviction happens at roughly 2½ years old, the same age at which the mane becomes evident.
