STATUS SURVEY of AFRICAN GREEN PIGEON (Treroncalvus STATUS SURVEY OF AFRICAN GREEN PIGEON (Treroncalvus, Temminck, 1808) IN EKITI STATE, NIGERIA BY OWOLABI, BIBITAYO AYOBAMI B. Wildlife Management (EWM/13/5440) A THESIS IN THE DEPARTMENT OF ECOTOURISM AND WILDLIFE MANAGEMENT, SUBMITTED TO THE SCHOOL OF POST GRADUATE STUDIES, THE FEDERAL UNIVERSITY OF TECHNOLOGY,AKURE, ONDO STATE. IN PARTIAL FULFILLMENT OF THE REQUIREMENT FOR THE AWARD OF THE DEGREE OF MASTER OF AGRICULTURAL TECHNOLOGY IN ECOTOURISM AND WILDLIFE MANAGEMENT. OCTOBER 2015. ABSTRACT The study focused on assessment and survey of thestatus survey of African Green Pigeon in EkitiState,Nigeria. Following the reconnaissance survey of the state, five sites were purposively selected, which represented areas where African Green Pigeon were commonly sighted. These areas were Counting station A (Aramoko/IjeroEkiti), Counting station B (IsanEkiti), Counting station C (IkogosiEkiti), Counting station D (Awo/IgedeEkiti) and Counting station E (IyemeroEkiti). The study area represents a typical rain forest ecosystem. Three methods were used for collecting data for the study (Point count method, direct observation and vegetation assessment technique). A meantotal of 97 birds were counted during the wet and dry season of the study, 46during the dry season and 51 counted during the wet season.Total mean number of bird in Counting Station A in the dry period was 10 and 9 in the wet season, accounting for a standard error of 3 ± 2.186birds sighted in the dry season and 3 ± 2.646in the wet season. Counting Station B forest patches, had a total of 29 birds, 9 sighted in the dry and 14 in the wet period, 3 ± 1.201 as standard error of birds sighted in the wet season and 3 ± 1.527 foe the dry season while counting Station C forest patches with 8 birds sighted in the dry and 12 birds recorded in the wet season, having a standard error of 3 ± 2.603 birds sighted in the dry and 3 ± 0.577 in the wet season. Counting Station D forest patches produces a total of 10 birds sighted in the dry and 8 birds seen in the wet season accounting for a 3 ± 0.882birds sighted during the dry period and 3 ± 1.201 in the wet period. A total of 9 birds in the dry and 8 birds in the wet season in station E were seen with standard mean of 3 ± 2.309in the dry and 3 ± 1.527in the wet season. Five (5) tree species were used by the African Green Pigeon for feeding during the research while others were used for other activities. The result of the 100% enumeration sampling of treesabove 10 meters in quadrant of 25 x 25 meters in the five counting stations revealed a total of 130 tree stands, 44 species and 29 families. Station A has103 trees species from 38 genus and CHAPTER ONE 1.0 INTRODUCTION Nigeria has about 940 out of about 1,850 species of bird in Africa, out of which 4 species are endemic, while 5 are rare or accidental species Lepage, (2006).Nigeria is a country of marked ecological diversity and climatic contrasts. According to the report of the FAO, the lowest point is the Atlantic Ocean at sea level while the highest point is the Chappal Waddi Mountain near the border of Cameroon, in the Gashaka-Gumpti National Park on the Mambilla Plateau in Taraba state at an elevation of 2,419m (7,936ft). Nigeria has diverse biophysical characteristics, ethnic nationalities, agro-ecological zones and socio-economic conditions (FAO 2010, FMEN 2001). Ecological diversity and climatic variation of the country, coupled with changes in composition of bird species are correlated with vegetation structure, topography, related physical and biological features varying along the altitudinal gradients Mallet-Rodrigues et al.,(2010). Birds are among the best known parts of the earth's biodiversity, but quantified knowledge is far from complete for most species and this leads to an obstacle in conservation of birds (Aerts et al., 2008; Mason et al., 2005). Birds play a vital role in floral biology and pollination of plants; about half of the plants communities are clearly adapted to bird pollination as well as indicates environmental health and they have been considered as indicator species of inhabited areas (Colwell, 2010, Rajashekara and Venkatesha, 2011). Newton, (2004) acknowledged the fact that, in the last 400 years, human actions alone eliminated about 127 of approximate 9,672 modern species of birds. Activities like fire wood collection, logging, agriculture, farming, drainage construction, filling of wetlands, human settlement, building of infrastructures, roads and industries among others have altered lots of habitats. Myer (1992) reported that, the loss of tropical ecosystem is of particular concern Full text of this document can be accessed by visiting the Post Graduate Research Unit of Albert Ilemobade Library, FUTA or contact the Reference Librarian via [email protected] .

  • Comments on the Ornithology of Nigeria, Including Amendments to the National List
    Robert J. Dowsett 154 Bull. B.O.C. 2015 135(2) Comments on the ornithology of Nigeria, including amendments to the national list by Robert J. Dowsett Received 16 December 2014 Summary.—This paper reviews the distribution of birds in Nigeria that were not treated in detail in the most recent national avifauna (Elgood et al. 1994). It clarifies certain range limits, and recommends the addition to the Nigerian list of four species (African Piculet Verreauxia africana, White-tailed Lark Mirafra albicauda, Western Black-headed Batis Batis erlangeri and Velvet-mantled Drongo Dicrurus modestus) and the deletion (in the absence of satisfactory documentation) of six others (Olive Ibis Bostrychia olivacea, Lesser Short-toed Lark Calandrella rufescens, Richard’s Pipit Anthus richardi, Little Grey Flycatcher Muscicapa epulata, Ussher’s Flycatcher M. ussheri and Rufous-winged Illadopsis Illadopsis rufescens). Recent research in West Africa has demonstrated the need to clarify the distributions of several bird species in Nigeria. I have re-examined much of the literature relating to the country, analysed the (largely unpublished) collection made by Boyd Alexander there in 1904–05 (in the Natural History Museum, Tring; NHMUK), and have reviewed the data available in the light of our own field work in Ghana (Dowsett-Lemaire & Dowsett 2014), Togo (Dowsett-Lemaire & Dowsett 2011a) and neighbouring Benin (Dowsett & Dowsett- Lemaire 2011, Dowsett-Lemaire & Dowsett 2009, 2010, 2011b). The northern or southern localities of species with limited ranges in Nigeria were not always detailed by Elgood et al. (1994), although such information is essential for understanding distribution patterns and future changes. For many Guineo-Congolian forest species their northern limit in West Africa lies on the escarpment of the Jos Plateau, especially Nindam Forest Reserve, Kagoro.

  • 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.

    Birding Tour to Ghana Specializing on Upper Guinea Forest 12–26 January 2018 Chocolate-backed Kingfisher, Ankasa Resource Reserve (Dan Casey photo) Participants: Jim Brown (Missoula, MT) Dan Casey (Billings and Somers, MT) Steve Feiner (Portland, OR) Bob & Carolyn Jones (Billings, MT) Diane Kook (Bend, OR) Judy Meredith (Bend, OR) Leaders: Paul Mensah, Jackson Owusu, & Jeff Marks Prepared by Jeff Marks Executive Director, Montana Bird Advocacy Birding Ghana, Montana Bird Advocacy, January 2018, Page 1 Tour Summary Our trip spanned latitudes from about 5° to 9.5°N and longitudes from about 3°W to the prime meridian. Weather was characterized by high cloud cover and haze, in part from Harmattan winds that blow from the northeast and carry particulates from the Sahara Desert. Temperatures were relatively pleasant as a result, and precipitation was almost nonexistent. Everyone stayed healthy, the AC on the bus functioned perfectly, the tropical fruits (i.e., bananas, mangos, papayas, and pineapples) that Paul and Jackson obtained from roadside sellers were exquisite and perfectly ripe, the meals and lodgings were passable, and the jokes from Jeff tolerable, for the most part. We detected 380 species of birds, including some that were heard but not seen. We did especially well with kingfishers, bee-eaters, greenbuls, and sunbirds. We observed 28 species of diurnal raptors, which is not a large number for this part of the world, but everyone was happy with the wonderful looks we obtained of species such as African Harrier-Hawk, African Cuckoo-Hawk, Hooded Vulture, White-headed Vulture, Bat Hawk (pair at nest!), Long-tailed Hawk, Red-chested Goshawk, Grasshopper Buzzard, African Hobby, and Lanner Falcon.

    Zambia and Zimbabwe 28 ovember – 6 December 2009 Guide: Josh Engel A Tropical Birding Custom Tour All photos taken by the guide on this tour. The Smoke that Thunders: looking down one end of the mile-long Victoria Falls. ITRODUCTIO We began this tour by seeing one of Africa’s most beautiful and sought after birds: African Pitta . After that, the rest was just details. But not really, considering we tacked on 260 more birds and loads of great mammals. We saw Zambia’s only endemic bird, Chaplin’s Barbet , as well as a number of miombo and broad-leaf specialties, including Miombo Rock-Thrush, Racket-tailed Roller, Southern Hyliota, Miombo Pied Barbet, Miombo Glossy Starling, Bradfield’s Hornbill, Pennant-winged ightjar, and Three-banded Courser. With the onset of the rainy season just before the tour, the entire area was beautifully green and was inundated with migrants, so we were able to rack up a great list of cuckoos and other migrants, including incredible looks at a male Kurrichane Buttonquail . Yet the Zambezi had not begun to rise, so Rock Pratincole still populated the river’s rocks, African Skimmer its sandbars, and Lesser Jacana and Allen’s Gallinule its grassy margins. Mammals are always a highlight of any Africa tour: this trip’s undoubted star was a leopard , while a very cooperative serval was also superb. Victoria Falls was incredible, as usual. We had no problems in Zimbabwe whatsoever, and our lodge there on the shores of the Zambezi River was absolutely stunning. The weather was perfect throughout the tour, with clouds often keeping the temperature down and occasional rains keeping bird activity high.

Rep. 77 (2011) The forests of eastern Ghana, with special reference to birds and conservation status by Françoise Dowsett-Lemaire & Robert J. Dowsett 1. INTRODUCTION Most of the dry forests of eastern Ghana are on hills and small plateaux at altitudes of 200-400 m, reaching 600-800 m on the highest ridges (as south of Kyabobo, and near Afadjato and Amedzofe). The highlands of eastern Ghana consist mostly of two long parallel ranges of hills stretching north-south, between 8°30'N (where they end in Ghana, but continue further north into Togo) and 6°35'N. South of 7°N only the eastern range remains, from the high ridges on the Togo border at Afadjato south-westwards towards the town of Ho at 6°35'N. The northern ranges are separated by a rather narrow valley passing through the towns of Nkwanta, Kadjebi, Jasikan to Hohoe. South of Ho, the coastal plain starts, and an interesting type of dry forest can be found in the Kalakpa floodplain in the wildlife reserve of that name. Most of the natural vegetation of eastern Ghana in the past must have consisted of transition wood - land and dry semi-evergreen rain forest (syn.

    MALAWI: MIOMBO MAGIC SEPTEMBER 1-18, 2020 ©2019 Sable Antelope © Dion Hobcroft Malawi: Miombo Magic, Page 2 This little-known country is emerging as one of the birding and wildlife gems of the amazing African continent. Best known for the great lake that dominates the east of the country, Malawi, with its low population and relatively large areas of varied habitats, ensures a spectacular list of many African birds difficult to see in more familiar African tourist destinations like South Africa, Uganda and Tanzania. Combined with some amazing conservation efforts and the development of superb accommodations and national park infrastructure the tourists are starting to arrive in numbers. It is a good opportunity to visit before this well-kept secret becomes widely known. On this tour we will visit the montane Nyika National Park, Dzalanyama Forest, the lush lowlands of Liwonde National Park, Lake Malawi itself in the region of Chintheche and both the Viphya Plateau and Zomba Massif. All of these locations offer different habitats from the famously bird rich Miombo and Mopane woodlands, cloud forest, stunning wetlands, floodplains and excellent rolling montane grasslands. Birding is outstanding and we expect a list of between 300-350 species including several Southern Rift endemics. Some of the special birds we will be searching for include Denham’s Bustard, Dickinson’s Kestrel, Boehm’s Bee-eater, Schalow’s Turaco, Pel’s Fishing-owl, Rwenzori Nightjar, Montane Blue Swallow, Babbling Starling, Boulder Chat, Yellow-throated Apalis, Red-tufted Sunbird, Locust Finch and Peter’s Twinspot to mention a few. Beyond the birds we can expect to see a good cross-section of mammals: African Elephant, Crayshaw’s Zebra, Eland, Roan and Sable Antelope, Waterbuck, Bushbuck, Klipspringer Grey Duiker, Cape Buffalo, Hippopotamus, Yellow Baboon, Samango Monkey, Thick-tailed Galago, Spotted Hyaena, Lion, Serval and leopard are all possible.

  • Resource Use in Indigenous Forests of the Eastern Cape, South Africa and Its Effects on Bird Communities
    Resource use in indigenous forests of the Eastern Cape, South Africa and its effects on bird communities by Jessica Leaver Dissertation presented for the degree of Doctor of Philosophy in the Faculty of Science at Stellenbosch University Promoter: Prof. M.I. Cherry March 2020 i Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this dissertation electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Copyright © 2020 Stellenbosch University All rights reserved ii Stellenbosch University https://scholar.sun.ac.za Abstract Indigenous forest represents South Africa’s most limited and fragmented biome, but supports disproportionality high levels of biodiversity. Furthermore, forests provide a range of resources for people, particularly the rural poor, and are thus of high socio-economic value. This is particularly true in the Eastern Cape, which harbours 46% of South Africa’s remaining indigenous forest cover, and some of the country’s most economically impoverished populace. Forest management in this region is thus required to balance the needs of resource users with the conservation of forest biodiversity through sustainable use. However, de facto open-access systems of resource use prevail, and there is concern that unregulated harvesting of forest products is driving forest degradation. Supporting this, a recent study found forest bird ranges to have declined in the region over the past 20 years, despite no loss of forest cover over the same time period.

MCTERNAN has been approved for the Program of Environmental Studies and the Voinovich School of Leadership and Public Affairs by Nancy J. Stevens Professor of Biomedical Sciences Mark Weinberg Dean, Voinovich School of Leadership and Public Affairs 3 ABSTRACT MCTERNAN, MICHAEL F., M.S., May 2019, Environmental Studies Conservation Potential of a Semi-Forested Agricultural Landscape: Diversity and Spatial Distribution of Birds within a Large-Scale Ugandan Coffee Farm Director of Thesis: Nancy J. Stevens Protected area conservation is not enough to stem increasing biodiversity loss. Therefore, it is important to consider private-owned lands when developing a long-term conservation strategy in a region. Agricultural lands, which cover more than 30 percent of the Earth’s terrestrial surface, are a good place to start. However, further research is needed to understand how species use the landscape, and what types of best practices should be encouraged to increase levels of biodiversity. This study was conducted on a 2500 ha semi-forested Ugandan Robusta coffee farm. The system is a hybrid of shade and full sun coffee production, with intense cultivation on production land and corridors of reserved indigenous forest.

  • Bird List for Gabon Mammal Watching Tour August 2019 (Taxonomy Follows the Clements Checklist of the Birds of the World)
    Bird List for Gabon Mammal Watching Tour August 2019 (Taxonomy follows the Clements Checklist of the Birds of the World) 147 species seen and three heard only This tour of Gabon, led by Fiona Reid, was focused primarily on the pursuit of mammals, but group members, also with an interest in birds (Debs Bradley, Laura Busby and Keith Millar) were able to record 150 species. While not a particularly high total for Gabon, no sound recordings were used and our total did include a number of sought-after species. Highlights included three hawk eagles (Crowned, Ayer’s and Cassin’s); a close encounter with a Long-tailed Hawk; four species of owl, each seen exceptionally well; six species of hornbill, Bates’s Nightjar, several African Finfoot, Forbes’s Plover, Grey Pratincole, Spot-breasted Ibis, Black and Rosy Bee- eaters, a good tally of kingfishers and the uncommon Olivaceous Flycatcher. Hearing Dja River Scrub Warbler, while tracking Western Lowland Gorilla was admittedly tantalizing, but a clear case of mammalian prioritisation! As mentioned in the main report, a key management goal in Lope National Park is to protect regionally-rare savannah ecosystems within the continuous rainforest block through the use of fire. We found these savannah areas virtually devoid of birds. More broadly, in echoing the observations of Kevin Bryan and Sjef Oilers, members of Jon Hall’s mammal watching tour group in August 2018, we too noted a (worrying) lack of those species (particularly smaller birds) with more catholic habitat preferences and pan-African distributions. Evidence is still circumstantial as to whether these populations are being negatively impacted and how, but, the absence of a number of species that one would reasonably expect to see during a visit to the right habitat was evident.
