Birding Tour Comoros and Mayotte 30
BIRDING TOUR COMOROS AND MAYOTTE 30 SEPTEMBER – 10 OCTOBER 2020 Karthala Scops Owl is one of the targets – this one was photographed by Alan van Norman on our 2014 tour. www.birdingecotours.com [email protected] 2 | ITINERARY Comoros and Mayotte 2020 Our Birding Tour Comoros and Mayotte will visit all three islands of the Comoros as well as the island of Mayotte. Although Mayotte is a department and region of France, traditional Mayotte culture and ecology are most closely related to that of the neighboring Comoros islands, and biogeographically it is part of the Comoros. This tour allows a rare opportunity for any serious lister to hopefully connect with some of the rarest, most range-restricted, and/or endangered species on the planet. These include Karthala Scops Owl, Moheli Scops Owl, Anjouan Scops Owl (all three listed as Critically Endangered by IUCN), Mayotte Scops Owl, and many other birds, a large number of which are endemic to the Comoros with their respective subspecies being endemic to their specific island. Not only is the birding spectacular, but so too is the scenery and the variety in the fauna and flora that one picks up along the way. The trip, however, is quite strenuous, as the climbs are steep and the camping fairly basic. But the birds available soon make one forget about the lack of common luxuries. This tour will start on 30 September in consideration of those tour participants coming from our Birding Tour Madagascar: The Remote North, providing a two-day gap between tours because of rather unreliable flight connections from Antananarivo to the Comoros, where delays and even cancellations are common. -
Cyclones and Societies in the Mascarene Islands 17Th-20Th Centuries
American Journal of Climate Change, 2013, 2, 1-13 http://dx.doi.org/10.4236/ajcc.2013.21001 Published Online March 2013 (http://www.scirp.org/journal/ajcc) Cyclones and Societies in the Mascarene Islands 17th-20th Centuries Emmanuel Garnier1,2,3, Jérémy Desarthe3,4 1Churchill College, University of Cambridge, Cambridge, UK 2Institut Universitaire de France, Paris, France 3Centre de Recherche d’Histoire Quantitative (UMR CNRS), University of Caen, Caen, France 4Institute for Sustainable Development and International Relations, Sciences Po, Paris, France Email: [email protected] Received December 16, 2012; revised January 15, 2013; accepted January 22, 2013 ABSTRACT The recent IPCC-SREX report focuses on the impact of extreme weather events on societies and underlines the absence of reliable data to assert a solid link between them and the current global climate change. Thanks to the unpublished materials that are contained in historic archives, this article suggests studying the cyclones which affected the Mas- carene islands between 1654 and 2007 and which supply us with a catalog of hitherto unpublished events. Inspired by the Simpson-Saffir hurricanes Wind Scale, the research proposes a relative evaluation of the extremes of the region. It underlines the big fluctuations in the last three centuries and partially answers the current debate on the reliability of the data in relation to hurricanes and their link with the contemporary climate. The available archives show that this type of meteorological event has occurred frequently during the relevant historical period and that for that reason, has given rise to original strategies of adaptation on the part of the societies affected. -
Acridotheres Tristis Linnaeus, 1766 the Common Myna (Acridotheres Tristis) Is a Highly Commensal Passerine That Lives in Close Association with Humans
Acridotheres tristis Linnaeus, 1766 The common myna (Acridotheres tristis) is a highly commensal Passerine that lives in close association with humans. It competes with small mammals and birds for nesting hollows and on some islands, such as Hawaii and Fiji, it preys on other birds’ eggs and chicks. It presents a threat to indigenous biota, particularly parrots and other birdlife, in Australia and elsewhere. The common myna has been introduced to parts of South East Asia, New Zealand, eastern Australia and southern Africa and Madagascar. It is also present on many islands in the Atlantic Ocean (including the Canary Islands, St Helena and Ascension Island), Indian Ocean (including Réunion, Mauritius, Rodriguez north to Lacadive and Maldive Islands and east to Andaman and Solomon Islands, Samoa, Cook Islands, Society Islands and some otherNicobar French Islands) Polynesian and Pacific islands).

The Madagascar and Indian Ocean Islands Hotspot Ecosystem Profile Summary
The Madagascar and Indian Ocean Islands Hotspot Ecosystem Profile Summary 1 About CEPF Established in 2000, the Critical Ecosystem Partnership Fund (CEPF) is a global leader in enabling civil society to participate in and influence the conservation of some of the world’s most critical ecosystems. CEPF is a joint initiative of l’Agence Française de Développement (AFD), Conservation International, the European Union, the Global Environment Facility (GEF), the Government of Japan, the John D. and Catherine T. MacArthur Foundation and the World Bank. CEPF is unique among funding mechanisms in that it focuses on high-priority biological areas rather than political boundaries and examines conservation threats on a landscape scale. From this perspective, CEPF seeks to identify and support a regional, rather than a national, approach to achieving conservation outcomes and engages a wide range of public and private institutions to address conservation needs through coordinated regional efforts. CEPF’s first phase of investment in this hotspot ran from 2001 to 2006 and totaled US$4.25 million. A consolidation phase of US$1.4 million followed, though it was delayed due to the country’s political situation and ran from 2009 to 2012. CEPF’s investments achieved significant results, particularly by helping to establish more than 1 million hectares of new protected areas, improving the livelihoods of communities near several protected areas, and by developing a direct link between improving livelihoods and preserving biodiversity. CEPF’s support enabled the participation of a broad range of stakeholders—many of whom had never had the opportunity to operate independently—and also enabled more well-known organizations to take risks to undertake conservation efforts with uncertain outcomes. -

The Catalog of Fishes database (http://research.calacademy.org/ichthyology/catalog) on which this study is based, has been maintained for 25 years and includes information on more than 50,000 available species names of fishes, with more than 31,000 of them currently regarded as valid species. New marine species are being described at a rate of about 100–150 per year, with freshwater numbers slightly higher. In addition, over 10,000 generic names are available ones of which 3,118 are deemed valid for marine fishes (as of Feb. 19, 2010). This report concentrates on fishes with at least some stage of their life cycle in the sea. The number of valid marine species, about 16,764 (Feb. -
Indian Ocean Islands Comoros & Mayotte 12Th to 20Th October 2021 (9 Days)
Indian Ocean Islands Comoros & Mayotte 12th to 20th October 2021 (9 days) Mayotte Scops Owl by Daniel Keith Danckwerts Sprinkled on the tropical seas off East Africa are a series of islands where paradise is defined! On our exploration of these idyllic isles, we will search for birds in the most spectacular scenery, be it rugged, forest-clad volcanic peaks, verdant forest patches or white, shell-laden beaches, fringed by warm water and teeming coral reefs. Island wildlife is generally susceptible to extinction and the islands of this area are no exception, with birds like the unfortunate Dodo serving as stark reminders of Mans’ heavy hand in these sensitive environments. RBL Indian Ocean Islands – Comoros Itinerary 2 The Comoros form an archipelago of volcanic islands off the central-east African coast. They are divided between the Union of the Comoros, a sovereign nation formed by the three islands of Grande Comoro, Anjoua & Mohéli, and the French overseas department of Mayotte. The vast evergreen forests that once dominated these islands have largely been removed leaving a few remaining pockets of pristine habitat boasting roughly 24 endemic species (and likely to reach a staggering 40 with further research). The addition of incredible scenery, a series of easily approachable active volcanoes and particularly friendly locals have made these islands an enticing and rewarding experience. We welcome you to join us as we island-hop with binoculars in hand on our quest to find the birds of these heavenly Indian Ocean isles.

These small island images (© CNES, Distribution Airbus Defence and Space) acquired territories have very fragmented and diversified environments. Land cover and land-use mapping of between July 2013 and July 2014. such environments requires satellite images with high spatial resolution. Unfortunately, the land use products available so far were only at low resolutions (usually from 4 kilometers to 250 meters). We used a hierarchical object-based image analysis method, ® implemented in eCognition software. The object-oriented approach is 1. When studying the geography and ecology of vector-borne diseases in small islands, high spatial divided into two main stages, segmentation and classification. The resolution is also fundamental to measure the favorable or unfavorable conditions to the presence of segmentation consists in grouping the pixels with their neighbors to the vectors and pathogens or to characterize the physical environmental of the people who have create objects larger and bigger by respecting thresholds uniformity. -
Birding the Comoros and Mayotte - Conservation Tour
BIRDING THE COMOROS AND MAYOTTE - CONSERVATION TOUR 30 SEPTEMBER – 10 OCTOBER 2022 30 SEPTEMBER – 10 OCTOBER 2023 Karthala Scops Owl is one of our four owl targets on this tour (photo Alan van Norman). www.birdingecotours.com [email protected] 2 | ITINERARY Comoros and Mayotte During our Comoros and Mayotte birding adventure, we will visit all four islands of the Comoros archipelago. This tour allows a rare opportunity for any serious lister to connect with some of the rarest, most range-restricted, and/or endangered species on the planet. These include Karthala Scops Owl, Moheli Scops Owl, Anjouan Scops Owl (with all three being listed as Endangered by the IUCN), Mayotte Scops Owl, and many other fantastic species, a large number of which are endemic to the Comoros (with their respective subspecies being endemic to their specific island). Apart from the owls mentioned above, we will also target numerous other endemic birds of the Comoros/Mayotte, as well as some more widespread Malagasy/Indian Ocean Islands endemics. These include Comoros Green Pigeon, Comoros Blue Pigeon, several localized white-eyes, brush-warblers and drongos, the beautiful Comoros Fody and Red Fody, Malagasy Paradise Flycatcher, Lesser and Greater Vasa Parrots and lots of others (please see the details within the itinerary below). Crab-plover is another of our targets: although less range-restricted than the other species mentioned, it’s a charismatic, beautiful tropical wader/shorebird. Not only is the birding spectacular, but so too is the scenery and the variety of fauna and flora that one picks up along the way as a byproduct of the birding.
