Madagascar's BIRDS DESTINATIONS endemics, anyone? MADAGASCAR’S BIRDS TEXT MARTIN BENADIE Rated as one of 12 mega-diversity hot- spot countries in the world, Madagas- car seems to belong to neither Africa nor Asia, but exudes an atmosphere distinctly its own. For the first-time birder to the island, it abounds with lifers. Mesites, ground-rollers, couas, vangas, Malagasy warblers and a host of other species are found nowhere else on the planet. lthough an island – albeit the fourth larg- est in the world, with an extent of about 587 000 square kilometres – Madagascar Ais sometimes referred to as the earth’s eighth con- tinent because its wildlife is so unique. Among the several reasons for its extraordinary assem- blages of flora and fauna is a long period of iso- lation; the island split away from Africa about 165 million years ago and reached its current po- sition some 80 million years ago. Another con- tributing factor is the combination of random colonisation from Africa and speciation from a small population of founders. As a result, more than 80 per cent of the wildlife is endemic, in- cluding mammals such as lemurs and a host of MARTIN BENADIE fascinating reptiles and amphibians. > MAY/JUNE 2018 MADAGASCAR 47 represented by the newtonias and Ward’s Vanga. Overall, they take on roles occupied elsewhere by woodpeckers, woodhoopoes, shrikes, tits, treecreepers and nuthatches. The mesites of the family Mesi- tornithidae are rail-like terrestrial birds with short, rounded wings and long, constantly flicking tails. They can fly, but rarely do so and are usually found in vocal pairs or small groups on the forest floor. Also terrestrial are the ground- rollers of the family Brachypteraci- idae, but they are harder to see as they are secretive and elusive.

  • Madagascar, 1998
    A mammal, bird, reptile, orchid and people-watching trip to - Madagascar (and a very short stay in Mauritius) 18-10-98 to 21-11-98 Dave Siems and Steve Anyon-Smith “weird (verb) – Madagascar” ------------------------------------------------------------------------------------------------------------ When our first guide, Patrice Rabearisoa, asked us what we wanted to see, he went white (not easy) at our reply – “we want to see all the birds, mammals, reptiles, orchids and everything else of interest in the forest, in no particular order.” He showed us all these things and more in the paradise that was, and still is, in parts, Madagascar. Outline of Trip “Madagascar” I said to Dave, and his eyes lit up. Five weeks later we were looking at lemurs. Our advice was that there was no safe or even practical way to visit a country populated by thieves, thugs and other human detritus of the worst order. There was said to be no usable public transport and if the food or the locals didn’t kill you, the insects most definitely would. So Dave and I set out to test these propositions. Madagascar is renowned for its wildlife, political instability and not much else. Our mission was to see as much of the native fauna and flora as possible during a five-week stay. We used public transport at all times and hired local guides at every location (this is generally compulsory anyway). We scattered ourselves widely throughout the country as the habitats are extremely varied, boasting rainforest, semi-desert, the so-called spiny forest and anything in between. Our expectations for the trip were not high given that we had little prior information and fully expected to be roasted slowly over a kitchen fire somewhere if we had managed to avoid perishing in a traffic accident.

  • MADAGASCAR: the Wonders of the “8Th Continent” a Tropical Birding Custom Trip
    MADAGASCAR: The Wonders of the “8th Continent” A Tropical Birding Custom Trip October 20—November 6, 2016 Guide: Ken Behrens All photos taken during this trip by Ken Behrens Annotated bird list by Jerry Connolly TOUR SUMMARY Madagascar has long been a core destination for Tropical Birding, and with the opening of a satellite office in the country several years ago, we further solidified our expertise in the “Eighth Continent.” This custom trip followed an itinerary similar to that of our main set-departure tour. Although this trip had a definite bird bias, it was really a general natural history tour. We took our time in observing and photographing whatever we could find, from lemurs to chameleons to bizarre invertebrates. Madagascar is rich in wonderful birds, and we enjoyed these to the fullest. But its mammals, reptiles, amphibians, and insects are just as wondrous and accessible, and a trip that ignored them would be sorely missing out. We also took time to enjoy the cultural riches of Madagascar, the small villages full of smiling children, the zebu carts which seem straight out of the Middle Ages, and the ingeniously engineered rice paddies. If you want to come to Madagascar and see it all… come with Tropical Birding! Madagascar is well known to pose some logistical challenges, especially in the form of the national airline Air Madagascar, but we enjoyed perfectly smooth sailing on this tour. We stayed in the most comfortable hotels available at each stop on the itinerary, including some that have just recently opened, and savored some remarkably good food, which many people rank as the best Madagascar Custom Tour October 20-November 6, 2016 they have ever had on any birding tour.

  • Disaggregation of Bird Families Listed on Cms Appendix Ii
    Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1.

  • MADAGASCAR TRIP REPORT Aug.-‐Sept 2012 John Clark
    MADAGASCAR TRIP REPORT Aug.-Sept 2012 John Clark ([email protected]) Our London friends, Dick and Liz Turner, Mary Ward-Jackson and I spent almost 4 weeks in Madagascar. Our primary focus was Birds, But we were also interested in nature more Broadly and culture. The tour was excellently prepared By our guide, Fanomezantsoa Andrianirina (Fano) – who was a perfect guide as well as Being great fun to travel with. The trip was excellent and we ended up seeing 122 of the endemic (and endemic Breeding) Birds of Madagascar, plus 54 non-endemics. Fano was not only an excellent Bird-guide himself, But he had lined up local guides in most of the locations – most of whom were terrific (especially, perhaps, Jaqui in Ampijoroa). Fano is doing much to help develop these local guides as more experienced and confident bird-guides in their own right. The logistics and places to stay were excellent – well, as excellent as an inevitaBle dependence on Madagascar Air permits! (They don’t call it Mad. Air for nothing; it is quite the worst airline I have ever had to use!). Fano’s drivers were also terrific (and keen budding birders!) So our main advice, for those planning a birding (or indeed broader nature/wildlife) trip to Mad. is to use Fano if at all possible.

  • The Natural Choice for Wildlife Holidays Welcome
    HOLIDAYS WITH 100% FINANCIAL PROTECTION The natural choice for wildlife holidays Welcome After spending considerable time and effort reflecting, questioning what we do and how we do it, and scrutinising the processes within our office and the systems we use for support, I am delighted to say that we are imbued with a new vigour, undiminished enthusiasm, and greater optimism than ever. My own determination to continue building on the solid foundation of twenty years of experience in wildlife tourism, since we started from very humble beginnings – to offer what is simply the finest selection of high quality, good value, tailor-made wildlife holidays – remains undaunted, and is very much at the core of all we do. A physical move to high-tech office premises in the attractive city of Winchester leaves us much better connected to, and more closely integrated with, the outside world, and thus better able to receive visitors. Our team is leaner, tighter, more widely travelled and more knowledgeable than ever before, allowing us to focus on terrestrial, marine and – along with Dive Worldwide – submarine life without distraction. In planning this brochure we deliberately set out to whet the appetite, and make no mention of either dates or prices. As the vast majority of trips are tailored to our clients’ exact requirements – whether in terms of itinerary, duration, standard of accommodation or price – the itineraries herein serve merely as indications of what is possible. Thereafter, you can refine these suggestions in discussion with one of our experienced consultants to pin down your precise needs and wants, so we can together create the wildlife holiday of your dreams.

  • Discovery of a Relict Lineage and Monotypic Family of Passerine Birds
    Discovery of a relict lineage and monotypic family of passerine birds Based on a comprehensive molecular dataset of passerines birds we identified a branch with a single species, the Spotted Wren-babbler Spelaeornis formosus. We suggest that this represents a relict lineage, which we propose should be placed in its own family, Elachuridae. The scientific name Elachura formosa should be used. We analysed of one of the most comprehensive datasets to date of the largest passerine bird clade, Passerida, which comprises c. 36% of the World’s c. 10,500 bird species. We identified 10 primary branches in the tree. One of these primary branches was made up of a single species, the Spotted Wren-Babbler Spelaeornis formosus, which is a small Wren-like bird that occurs in mountains from the eastern Himalayas to southeast China. This species apparently represents an old branch in the large passerine tree, without any close living relatives. There have surely been other relatives on this branch, which have gone extinct. The fact that it resembles wren-babblers and wrens in appearance is either due to pure chance or to convergent evolution, which may result in similar appearances in unrelated species that live in similar environments. We proposed the new family name Elachuridae for this single species. We also suggested that the scientific name Elachura formosa should be used, and the English name be changed to Elachura, to highlight its distinctness. Timaliidae (56) Pellorneidae (69) Leiothrichidae (133) Zosteropidae (128) Sylviidae (70) Pnoepygidae

    MADAGASCAR: The Wonders of the “8th Continent” A Tropical Birding Set Departure November 3—28, 2013 Guide: Ken Behrens All photos taken during this trip. All photos by Ken Behrens unless noted otherwise. TOUR SUMMARY Madagascar has long been a core destination for Tropical Birding, and with last year’s opening of a satellite office in the country, we have further solidified our expertise in the “Eighth Continent.” This was another highly successful set-departure tour to this special island. It included both the Northwestern Endemics Pre-Trip at the start and the Helmet Vanga extension to the Masoala Peninsula at the end. Although Madagascar poses some logistical challenges, especially in the form of the national airline Air Madagascar, we had no problems on this tour, not even a single delayed flight! The birding was great, with 196 species recorded, including almost all of the island’s endemic birds. As usual, the highlight was seeing all five of the incredible ground-rollers, from the roadrunner-like Long-tailed of the spiny forest to the wonderful rainforest-dwelling Scaly. There was a strong cast of vangas, including Helmet, Bernier’s, and Sickle-billed. In fact, we saw every member of the family save the mysterious Red-tailed Newtonia which is only regularly seen in the far south. As normal, the couas were also a favorite. From the shy and beautiful Red-breasted of Madagascar Set Departure Tour Nov. 3-28, 2013 the eastern rainforest to the huge Giant Coua of the dry western forest, we were looking for and at couas virtually every day! The bizarre mesites form a Malagasy endemic family, and we had superb extended views of all three members of the family.

  • Trip Report BA048 Madagascar Nov2016.Pages
    ! Birding Africa Madagascar Tour 14 November - 5 December 2016 Tour Report by leader Michael Mills Photos by participants Don MacGillivray & Martin Painter (Helmet Vanga) www.birdingafrica.com Our comprehensive 2016 Madagascar Tour once again showcased Madagascar’s best birds and wildlife in just 16 days, with an optional five days spent at Masoala at the end. We enjoyed excellent views of all available endemic birds, making it our most successful tour of Madagascar to date. Among the 190 species logged were all five species of Ground Roller, all three Mesites, all species of Vanga, all ten Couas and all four Asity species. The most enjoyed birds of the trip were Rufous-headed Vanga and Crossley’s Vanga in tie ninth, Pitta-like Ground Roller and Giant Coua in tie seventh, Short-legged Ground Roller in sixth, Scaly Ground Roller in fifth, White-breasted Mesite in fourth, Long-tailed Ground Roller in third, and Velvet Asity in second, and the peerless Helmet Vanga took our top honours! We also recorded 25 lemur species and lots of other great critters. Deservedly called the eighth continent, Madagascar is simply one of the most unusual and spectacular wildlife destinations on the globe. With more than 120 bird endemics and several endemic bird families, plus all the unique mammals and habitats, we met up at our comfortable base hotel in Antananarivo, exhilarated at what the coming weeks held for us. A short stint of birding in the hotel gardens with Madagascar Nightjar on its day roost tickled our taste buds before we enjoyed our first of many scrumptious meals together.
