Sierra Leone Rockfowl and Upper Guinea Specials 21St February to 7Th March 2022 (15 Days)
Sierra Leone Rockfowl and Upper Guinea Specials 21st February to 7th March 2022 (15 days) White-necked Rockfowl by Adam Riley RBL Sierra Leone Itinerary 2 Sierra Leone is a core West African destination, offering visitors a diverse range of exciting Upper Guinea forest birds and mammals. Rockjumper pioneered this tour during reconnaissance trips in 2005 and then led three successful tours in the course of 2006; these being the first-ever birding tours to the country. Sierra Leone’s biologically rich rainforests support no less than 15 of the 16 Upper Guinea endemic bird species, including the fabled White-necked Rockfowl that will form the basis of our tour. Forest specialties abound and we will focus on finding the rare Gola Malimbe, Sierra Leone Prinia, Black-headed Rufous Warbler, Hartlaub’s Duck, Brown-cheeked Hornbill, Sharpe’s Apalis, Kemp’s Longbill, White-breasted Guineafowl and Red-cheeked Wattle-eye; while the wooded savannas are home to the stunning Emerald Starling, Crimson Seedcracker and Turati’s Boubou, to name but a few.

Last updated on Jan. 15, 2019 Traveling to the White Continent Te Drake Passage is the body of water that separates Cape Horn, the last piece of land belonging to the American continent, and the South Shetland Islands, located in Antarctica. Tis is where the Antarctic, the Pacific and the Atlantic oceans meet, which makes this merging point one of the most turbulent waters on Earth. 3 The traditional way from Ushuaia: 4 days crossing the Drake Passage To reach the Antarctic Peninsula, travel operators sail the tempestuous Drake Passage. But this comes with inconvenience for the traveller. · At least 50 hours South to reach the Antarctic peninsula · At least 50 hours North to get back to South America · Usually through rough seas, potentially causing sea sickness Watch Drake Passage video Highlight: Watch how crossing the Drake Passage looks like here.

The Role of Thermal Physiology in Recent Declines of Birds in a Biodiversity Hotspot

Tel: +27 41 504 2421. Email: [email protected] We investigated whether observed avian range contractions and population declines in the Fynbos biome of South Africa were mechanistically linked to recent climate warming. We aimed to determine whether there were correlations between preferred temperature envelope, or changes in temperature within species’ ranges, and recent changes in range and popula- tion size, for 12 Fynbos-resident bird species, including six that are endemic to the biome. We then measured the physiological responses of each species at air temperatures ranging from 24 to 42°C to determine whether physiological thermal thresholds could provide a mechanistic explanation for observed population trends. Our data show that Fynbos-endemic species occu- pying the coolest regions experienced the greatest recent reductions in range and population size (>30% range reduction between 1991 and the present). -
BIRDS OBSERVED at SEA DURING the VOYAGE of HMS BLONDE to HAWAII [1824-1826) by Storrs L
ROVAL NAVAL BIRDWATCHING SOCIETY (1995) • Sea Swallow 44. BIRDS OBSERVED AT SEA DURING THE VOYAGE OF HMS BLONDE TO HAWAII [1824-1826) By Storrs L. Olson. It seems appropriate to put on record here some reports of birds observed at sea aboard a vessel of the Royal Navy that have remained unpublished for almost a century and three-quarters. In 1824 the 46-gun frigate Blonde departed England on a diplomatic mission to the Hawaiian Islands, under the command of George Anson, Lord Byron, who had succeeded to that title only a few months previously, upon the death of his cousin, the renowned poet. The Blonde crossed the Atlantic to Brazil by way of Madeira, sailed round Cape Horn, stopping in Chile, Peru, and the Galapagos, before arriving in Hawaii. She returned in 1826 via Maiden Island, Mauke [in the Cook group), Chile, and St. Helena. Aboard was a youthful and largely untrained naturalist, Andrew Bloxam, who prepared specimens and kept natural history notes during the voyage. Apart from a few observations incidentally included in a volume that appeared under Byron's name [Byron 1827] that was cobbled together by a compiler from several diaries, virtually nothing was published on the natural history of the voyage until I began my studies of Bloxam's manuscript natural history notes, which are housed at the British Museum [Natural History) [Olson 1986, in press a,b). These notes contain several references to landbirds observed at sea, as well as seabirds. There are several transcriptions of Bloxam's notes. The passages that follow are from a fair copy, with additional or variant information from rougher notes inserted in brackets [ ]. -

Management Plan for Antarctic Specially Protected Area No
Measure 2 (2005) Annex E Management Plan for Antarctic Specially Protected Area No. 120 POINTE-GÉOLOGIE ARCHIPELAGO, TERRE ADÉLIE Jean Rostand, Le Mauguen (former Alexis Carrel), Lamarck and Claude Bernard Islands, The Good Doctor’s Nunatak and breeding site of Emperor Penguins 1. Description of Values to be Protected In 1995, four islands, a nunatak and a breeding ground for emperor penguins were classified as an Antarctic Specially Protected Area (Measure 3 (1995), XIX ATCM, Seoul) because they were a representative example of terrestrial Antarctic ecosystems from a biological, geological and aesthetics perspective. A species of marine mammal, the Weddell seal (Leptonychotes weddelli) and various species of birds breed in the area: emperor penguin (Aptenodytes forsteri); Antarctic skua (Catharacta maccormicki); Adélie penguins (Pygoscelis adeliae); Wilson’s petrel (Oceanites oceanicus); giant petrel (Macronectes giganteus); snow petrel (Pagodrama nivea), cape petrel (Daption capense). Well-marked hills display asymmetrical transverse profiles with gently dipping northern slopes compared to the steeper southern ones. The terrain is affected by numerous cracks and fractures leading to very rough surfaces. The basement rocks consist mainly of sillimanite, cordierite and garnet-rich gneisses which are intruded by abundant dikes of pink anatexites. The lowest parts of the islands are covered by morainic boulders with a heterogenous granulometry (from a few cm to more than a m across). Long-term research and monitoring programs of birds and marine mammals have been going on for a long time already (since 1952 or 1964 according to the species). A database implemented in 1981 is directed by the Centre d'Etudes Biologiques de Chize (CEBC-CNRS). -

Guided by our ornithologist, Jim Wilson, our birders were first out, keen to find their target species, the Magellanic woodpecker. In this they were more than successful, spotting five, both males and females. Meanwhile, the rest of us boarded a catamaran and sailed the Beagle Channel towards the national park. En route we visited several small rocky islands, home to South American sea lions, imperial and rock cormorants (or shags), and South American terns. Disembarking in the national park at Lapataia Bay, we enjoyed lunch and walking trails through the southern beech forest with views of the Beagle Channel and Lago Roca before heading back to Ushuaia by bus. Awaiting us there was our home for the next few weeks, the Island Sky. Once settled in our cabins, we went out on deck to watch the lines being cast off and we sailed out into the Beagle Channel. Our Antarctic adventure had begun! Sunday, January 27 At Sea Our day at sea began with Jim introducing us to the birds of the Falkland Islands, and preparing us for our upcoming wildlife encounters.
