The keen birders were the first away, on their mission to the Tierra del Fuego National Park in search of the Magellanic woodpecker. They were rewarded with sightings of both male and female woodpeckers, Andean condors, flocks of Austral parakeets, and a wonderful view of an Austral pygmy owl, as well as a wide variety of other birds to check off their lists. The majority of our group went off on a catamaran tour of the Beagle Channel, where we saw South American sea lions on offshore islands before sailing on to the national park for a walk along the shore and an enjoyable Argentinian BBQ lunch. Others chose to hike in the deciduous beech forests of Reserva Natural Cerro Alarkén around the Arakur Resort & Spa. After only a few minutes of hiking, we saw an Andean condor soar above us and watched as a stunning red and black Magellanic woodpecker flew towards us and perched on the trunk of a nearby tree. -

Title, Antarctic Village – No Borders Author, Ann Marie Pena First published, The Hub Date, March 2007 Bandera Antártida Hacia el sur en el blanco profundo se fundieron los colores del mundo y el silencio se hizo voz y el amor se hizo agua, y el agua se hizo paz y belleza Antártida, Antártida, escuela de humildad de ciencias y,... ecoamistad. Antártida, Antártida, altar de hielo y luz, reserva de agua y paz. Manuscrito en una servilleta Hotel Savoy, Rosario 1992 Antarctica, the end of the world: boasting the most hostile climatic conditions, the coldest place on earth with temperatures reaching -80 °C in winter, the largest frozen desert in the world, continaing 90% of the world's ice (approximately 70% of the world's fresh water), no permanent human residents, and no indigenous population. Yet over 4,000 research scientists from 27 different nations are constantly monintering the ecoszone of this southernmost continent, not to mention the hundreds and thousands of new eco-tourists aboard the cruise ships navigating the Half Moon Island, Whalers Bay, Deception Island, Paradise Harbor, Port Lockroy, Petermann Island. “[…] Vowing one day to venture to these invariably far-flung and often wholly inhospitable lands. Antarctica's treacherous, spiny tendril was one such irresistible location […] Like the bristly tail of some giant, prehistoric sea creature, the Antarctic Peninsula thrusts out past the Antarctic Circle, lunging vainly toward its sibling, the Andes, across the infamous Drake Passage. I'm standing on the bow of a modern ice vessel watching hefty chunks of disintegrating pack ice thud against the hull as we pick our way gingerly through a narrow channel. -

An Arctic Expedition To
The Association of Former Students of Texas A&M EXPEDITION TO AN ARCTIC Aboard the Exclusively Chartered, Five-Star L’Austral Jan. 28 - Feb. 10, 2020 Howdy, Ags! “Everything wears an aspect of unreality,” Ernest Shackleton wrote. “Icebergs hang upside down in the sky; the land appears as layers of silvery or golden cloud. Cloud‑banks look like land, icebergs masquerade as islands...” Watch as normal human scales and reference points disappear amidst the grandeur of nature in its most pristine form, from extended sunrises that paint the icescape in soft shades of pink to the lingering golden light of the austral summer, where humpback whales, leopard seals and Adélie penguins swim among sparkling turquoise glaciers and glimmering icebergs. Be among the fortunate few to set foot on the continent of Antarctica, and see how its spectacular illuminations reveal the majesty and contrasts of this unique wilderness during your extraordinary 14‑day journey to the bottom of the world. Retrace the sea lanes navigated by storied explorers Shackleton, Amundsen and Scott, inspired to seek out the final frontier of “The White Continent.” Cruise for nine nights aboard the exclusively chartered, Five‑Star, ice‑class L’Austral, one of the finest vessels in Antarctic waters. With private balconies in 95 percent of its ocean‑view accommodations and encompassing state‑of‑the‑art ship design and technology, L’Austral sets the very highest standards in elegance and comfort. The onboard expedition team of naturalists will guide you on excursions aboard sturdy Zodiac craft to satisfy your appetite for exploration amid floating ice sculptures, intricate ecosystems and abundant wildlife, especially penguins and seals that exhibit little or no fear of humans. -
