The Ostrich Vol THE OSTRICH VOL. 41, No. 1 & 2 1970 FOURTEENTH RINGING REPORT C. C. H. ELLIOTT& M. J. F. JARVIS Ringing Organizers INTRODUCTION To bring the reporting of South African ringing activities up to date, this report covers the five seasons from 1 July 1963 to 30 June 1968. It also covers an important period for the ringing scheme which has reached its twentieth year of existence and, as will be seen below. has increased in maturity, both in terms of the numbers of birds ringed and in terms of the number of specific and rewarding studies that have been carried out. It is hoped that, with the prospect of proper financing in the near future, the full adulthood of the scheme will be realised and that it will soon achieve an international standing comparable to any scheme in the world. By decision of the Council, this entire number of OJtrich is devoted to the Society’s ringing activities: firstly the five-year report and secondly accounts of special studies. SCHEDULE OF BIRDSRINGED This section incorporates certain innovations, amongst which is the listing of all species ringed since the inception of the scheme and the production of a grand total for each species. The number of birds ringed during the five years reviewed (I 88,396) almost equals the number ringed in the preceding 15 years (216,284). It does seem, however, that under the present organiza- tion and with the number of ringers operating, we have nearly reached a ceiling at about 45,000 birds per year, unless new methods of trapping (such as cannon nets) prove successful or unless the recruitment of new ringers improves. More important is that, although the annual total now ex- ceeds 40,000, the number of species ringed is unchanged. It has in fact dropped slightly in 1967-8. This is an indication that moreeffort is being put into particular studies. During the period reviewed supporters of the scheme undertook probably the most successful ringing operation ever mounted in Africa, namely the ringing in five years of 70,840 European Swallows Hiirnndo rrrstica. Apart from this study, heavy ringing programmes have been carried out on the Anatidae, including the Spurwinged Goose Plectropterus gntnbemis, Egyptian Goose Alopochen aegyptiacus, Shelduck Tadorna ca~zaand Yellowbilled Duck Anus undulata. In smaller numbers but just as important has been the ringing of many species of birds of prey, including a study of the Steppe Buzzard Buteo hutco. Programmes on the Crowned Guineafowl Nutnida Downloaded by [University of Cape Town Libraries] at 01:58 28 November 2014 nieleagris and Redknobbed Coot Fulica cristata have begun to bring in interesting results. The Palearctic waders have been ringed in increasing numbers, particularly the Common Sandpiper Tringa hypoleucos, Green Sandpiper T. orhropiis and Wood Sandpiper T. glareola. A special study has been made of the Carmine Bee-eater Miwps nrrbicoides. Lastly, several other groups of species have begun to be ringed in numbers and may soon bring in information. e.g. European Sandmartin Xiparia riparia, Willow Warbler Phyllosropirs trochilus, the Acrocephalines, the Mozambique Nightjar Caprirnirlgirsfossi and the House Sparrow Passer dorliesticus. Although the amount of ringing done by some official stations is increasing, the vast majority of birds (ca. 90 per cent) are still ringed by amateurs, usually operating through their clubs but some- times individually. Members of the Witwatersrand Bird Club, who have accounted for nearly 40 per cent of the total birds ringed, must be congratulated. Shown below is the distribution of ringing effort between theclubs and research stations. 1 2 ELLIOTT& JARVIS:14~~ RINGING REPORT OSTRICH41 Organization Organizer No. of bird.v ringed 1967-8 Witwatersrand Bird Club ... ... ...

Although the Society has no official retrap scheme as yet, certain clubs and diligent individual ringers have started their own systems. Of the data received so far, 159 retrap records have been included in this report on the grounds that either the retrap locality differed significantly from the ringing site or the time elapsed between ringing and retrapping was greater than three years. The 159 retraps include 79 of European Swallows Hirutido rustica, a number of which are “controlled” each year in Europe. The rate of recovery averaged at about 320 per year, which is not quite twice the number (187) recorded in the Thirteenth Ringing Report (McLachlan 1969). This section retains the form used in previous reports except that the Euring recovery code (see below) has been used for standard methods of recovery. Where additional interesting details are available, these have been included in the “other details” column. All countries outside southern Africa have been printed in heavy black type. In an attempt to make this section more readable, brief comments have been offered on points of interest emerging from some of the recoveries. In addition, long-distance recoveries have been marked with asterisks (*) and others of interest have been given crosses (t). The English names throughout have been taken from Birds of South Africa (McLachlan & Liversidge 1957) and Latin names from the new Check List of Birds of Sourh Africa (Winterbottom 1969). The report was written from data which, in a few cases, was of poor quality. Any errors or corrections found, should be submitted to the authors for inclusion in corrigenda in a future issue of Ostrich.

    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.

  • 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.

  • Thyroid Cancer in Children and Adolescents of Bryansk and Kaluga Regions
    BY0000285 Thyroid Cancer in Children and Adolescents of Bryansk and Kaluga Regions A.F. TSYB, E.M. PARSHKOV, V.V. SHAKHTARIN, V.F. STEPANENKO, V.F. SKVORTSOV, I.V. CHEBOTAREVA MRRC RAMS, Obninsk, Russia Abstract We analyzed 62 cases of thyroid cancer in children and adolescents of Bryansk and Kaluga regions, the most contaminated as a result of the Chernobyl accident. The data on specified radiation situation as well as probable radiation doses to the thyroid are given. It is noted that the development of thyroid cancer depends on the age of children at the time of accident (0-3, 7-9, 12-15 years). They arc the most critical periods for the formation and functioning of the thyroid, in particular, in girls. It is suggested that thyroid cancer develops in children and teenagers residing in areas with higher Cs-137 contamination level at younger age than in those residing in less contaminated regions. It is shown that the minimal latent period in the development of thyroid cancer makes up to 5 years. The results of ESR method on tooth enamel specimen indicate that over postaccident period the sufficient share of children has collected such individual radiation dose which are able to affect on their health stale and development of thyroid pathology. For a long period of time Russia unlike Belarus and Ukraine was considered to be "favourable" by the development of thyroid cancer in children and adolescents after the Chernobyl accident. Such a fact appeared to be a dissonance in the common concept on the possible radiation induction of thyroid tissues to malignancy when received relatively low doses of iodine radionuclide.

  • Systematic and Taxonomic Issues Concerning Some East African Bird Species, Notably Those Where Treatment Varies Between Authors
    Scopus 34: 1–23, January 2015 Systematic and taxonomic issues concerning some East African bird species, notably those where treatment varies between authors Donald A. Turner and David J. Pearson Summary The taxonomy of various East African bird species is discussed. Fourteen of the non- passerines and forty-eight of the passerines listed in Britton (1980) are considered, with reference to treatments by various subsequent authors. Twenty-three species splits are recommended from the treatment in Britton (op. cit.), and one lump, the inclusion of Jackson’s Hornbill Tockus jacksoni as a race of T. deckeni. Introduction With a revision of Britton (1980) now nearing completion, this is the first of two pa- pers highlighting the complexities that surround some East African bird species. All appear in Britton in one form or another, but since that landmark publication our knowledge of East African birds has increased considerably, and with the advances in DNA sequencing, our understanding of avian systematics and taxonomy is con- tinually moving forward. A tidal wave of phylogenetic studies in the last decade has revolutionized our understanding of the higher-level relationships of birds. Taxa pre- viously regarded as quite distantly related have been brought together in new clas- sifications and some major groups have been split asunder (Knox 2014). As a result we are seeing the familiar order of families and species in field guides and checklists plunged into turmoil. The speed at which molecular papers are being published continues at an unprec- edented rate. We must remember, however, that while many molecular results may indicate a relationship, they do not necessarily prove one.

  • Namibia & Botswana
    Namibia & Botswana: From the NAMIB to the OKAVANGO A Tropical Birding Set Departure September 5–20, 2015 Guide: Ken Behrens All photos taken by Ken Behrens during this trip TOUR SUMMARY Our Namibia and northern Botswana tour has long been one of our most popular, and for good reason. The Namib escarpment and desert hold a suite of endemic birds that is shared only with adjacent Angola. These include the handsome Hartlaub’s Francolin, taxonomic oddity Rockrunner, boldly pied White-tailed Shrike, and cryptic Dune Lark. Farther north and east, the Okavango system holds a great wealth of birds, including two of the continent’s most wanted species: White-backed Night-Heron and Pel’s Fishing-Owl. There is no better spot in Africa for these scarce and shy birds. Although they expect the special birds, birders are often also surprised by this tour’s richness of mammals. Etosha National Park is one of Africa’s great parks, and is at its best during the late dry season timing of this tour. The spectacle of thousands of big mammals crowding together for precious mouthfuls of water while trying to avoid the big predators that await in ambush, ranks among Earth’s great natural spectacles. And Etosha is just one of several sites on this trip that always have lots of mammals. But the real thing that makes tours in Namibia and Botswana special is not the specific birds and mammals that these countries hold, Namibia & Botswana September 5 – 20, 2015 but rather a magical quality to the landscapes of this part of the world.

  • Elgon Francolin Scleroptila Elgonensis Should Be Treated As a Species Distinct from Moorland Francolin S
    Elgon Francolin Scleroptila elgonensis should be treated as a species distinct from Moorland Francolin S. psilolaema Nigel Huntera, Michael Millsb,c and Callan Cohenb,c Le Francolin d’Elgon Scleroptila elgonensis devrait être traité comme une espèce distincte du Francolin montagnard S. psilolaema. Le Francolin montagnard Scleroptila psilolaema est généralement considéré comme comprenant quatre sous-espèces sur les haut-plateaux de l’Éthiopie, du Kenya et de l’est de l’Ouganda. Ce traitement est basé sur les préférences d’habitat partagées (landes afro-alpines) et les caractéristiques du plumage supposées similaires des quatre taxons, bien qu’avant 1963 ils n’étaient pas traités comme conspécifiques. Afin de déterminer si cette approche est acceptable, nous avons examiné les données vocales et morphologiques, ainsi que certaines données génétiques. Les données vocales en particulier montrent des différences qualitatives, les vocalisations du Francolin d’Elgon ressemblant plus à celles du Francolin de Shelley S. shelleyi et du Francolin d’Archer S. gutturalis qu’à celles du Francolin montagnard. Nous concluons que les oiseaux éthiopiens (‘Francolin montagnard’ S. psilolaema) et ceux du Kenya et de l’Ouganda (‘Francolin de l’Elgon’ S. elgonensis) devraient être traités comme des espèces distinctes. Summary. Moorland Francolin Scleroptila psilolaema is generally considered to comprise four subspecies in the highlands of Ethiopia, Kenya and eastern Uganda. This treatment is based on the shared habitat preferences (Afro-alpine moorland) and supposedly similar plumage characteristics of the four taxa, although prior to 1963 they were not treated as conspecific. To determine whether this approach is strongly supported, we examined vocal and morphological evidence, and reviewed the available genetic data.

Some species, such as the helmeted guineafowl (N. meleagris), Swainson’s spurfowl (P. swainsonii) and greywing francolin (S. africanus), thrive in moderate to heavily disturbed landscapes, mainly agriculture. In fact, hel- meted guineafowl and Swainson’s spurfowl increased both in abundance and range during the 20th century. Others, such as the redwing (S. levaillantii) and Orange River francolins (S. levaillantoides) are very sensitive to certain types of land use. These strikingly different responses to land use require equally diverse strategies in order to develop truly sustainable management strategies and policies.

  • New Francolin and Spurfowl Taxonomy
    TAXONOMY amebirds have been domest­ icated for food production and for ornamental aviculture Gfor centuries, yet they remain a mostly under­appreciated group of birds. This might be because they can be seen along roadsides, in open farmlands, urban fringes and even within towns and gardens. The gamebirds have rep­ resentatives on all continents except Antarctica and, together with the ducks and geese, form the basal group among the Neoaves. The Galliformes comprise nine major groups of terrestrial game­ birds: megapodes, cracids, guineafowls, grouse, turkeys, pheasants, partridges (including francolins and spurfowls), and Old World and New World quails. Studies combining the genetics and anatomy of living species and fossils JACQUES PITTELOUD suggested that pheasants, partridges, compared to the raucous crowing or above Plain-bellied Francolin Campocolinus quails, spurfowls and francolins are not cackling calls of spurfowls. hubbardi (male shown) has been elevated to natural evolutionary groups, but rather The African francolins are related to a full species. mosaics of evolutionarily unrelated the Asiatic francolins, the Junglefowl species.

Spotted Eagle-Owl Tour Summary The southern African sub-region has one of the highest number of endemic and near-endemic bird species on the continent. This, coupled with great infrastructure, makes South Africa a highly rewarding country to explore. Our first day was set to be an arrival day where everyone was met by their Rockjumper tour leader at our accommodation in South Africa’s largest city - Johannesburg.
