2020 Conservation Outlook Assessment
IUCN World Heritage Outlook: https://worldheritageoutlook.iucn.org/ Vallée de Mai Nature Reserve - 2020 Conservation Outlook Assessment Vallée de Mai Nature Reserve 2020 Conservation Outlook Assessment SITE INFORMATION Country: Seychelles Inscribed in: 1983 Criteria: (vii) (viii) (ix) (x) In the heart of the small island of Praslin, the reserve has the vestiges of a natural palm forest preserved in almost its original state. The famouscoco de mer, from a palm-tree once believed to grow in the depths of the sea, is the largest seed in the plant kingdom. © UNESCO SUMMARY 2020 Conservation Outlook Finalised on 01 Dec 2020 GOOD WITH SOME CONCERNS The protection and management of Vallée de Mai Nature Reserve is generally effective and is supported by a national legal framework, although there is a lack of a national protected area system. The management authority is very competent and is effectively implementing science-based programs and outreach and education schemes. However, the future of the site’s key value, the coco de mer palm, is still under threat from illegal collection and over-exploitation for its nuts and kernel. The site's management has reduced both commercial harvesting and illegal collection of nuts based on scientific research, although the conservation impacts of these requires further assessment. The National Government and the managing agency are implementing targeted conservation measures and aim to tighten law and legislation to protect the species, which include an increase in penalty for poaching of coco de mer nuts. Current priorities for the Nature Reserve include continuation and expansion of the outreach and education programme; promoting an increase in the size and connectivity of Vallée de Mai within the Praslin Island landscape, with a legally designated buffer zone; increasing anti-poaching; and continuing to control the harvesting of coco de mer seeds while expanding a program of replanting seedlings. -

Seychelles Birding Trip Report
Seychelles birding trip report From December 26 (2008) to January 6 (2009) we spend our Christmas holidays on the Seychelles. Curiosity was the main driving force to visit this archipelago in the Indian ocean. Our goals were to see various islands, relax on the wonderful beaches, enjoy the local cuisine, snorkel the coral reefs, and last but not least do some birdwatching. We tried to see and photograph as many as possible endemics and tropical sea birds. December or January is definitely not the best time to visit the Seychelles because it’s the rainy season, and it’s outside the breeding season, making it hard to see some bird species or good numbers. Indeed we had a few days with a lot of rain and other days with very cloudy skies and wind. About half of the time we had marvelous sunny beach weather. Day time temperature usually was around 30°C. With regard to birding the preparation consisted of reading a number of trip reports from internet (see: www.travellingbirder.com) and the ‘Birds of the Seychelles’ by Skerrett et al. (2001). To see all endemics of the northern island of the Seychelles (the so-called granitic group) at least 4 islands need to be visit: Mahe, Praslin, La Digue, and Cousin. The first three island can be visited at any time. Tourist day trips to Cousin are usually organized on Tuesdays and Fridays and departure from Praslin, but as it turned out not on January 2, the day we were planning to go there. A fisherman was willing to take us to Cousin on another date in his small boat for 175 Euro. -

Three Rare Parrots Added to Appendix I of CITES !
PsittaScene In this Issue: Three Rare Parrots Added To Appendix I of CITES ! Truly stunning displays PPsittasitta By JAMIE GILARDI In mid-October I had the pleasure of visiting Bolivia with a group of avid parrot enthusiasts. My goal was to get some first-hand impressions of two very threatened parrots: the Red-fronted Macaw (Ara rubrogenys) and the Blue-throated Macaw (Ara SceneScene glaucogularis). We have published very little about the Red-fronted Macaw in PsittaScene,a species that is globally Endangered, and lives in the foothills of the Andes in central Bolivia. I had been told that these birds were beautiful in flight, but that Editor didn't prepare me for the truly stunning displays of colour we encountered nearly every time we saw these birds. We spent three days in their mountain home, watching them Rosemary Low, fly through the valleys, drink from the river, and eat from the trees and cornfields.

Calcium Metabolism in Grey Parrots: the Effects of Husbandry
This watermark does not appear in the registered version - http://www.clicktoconvert.com Calcium metabolism in grey parrots: the effects of husbandry. Thesis submitted in accordance with the requirements of The Royal College of Veterinary Surgeons for the Diploma of Fellowship by Michael David Stanford. August 2005 1 This watermark does not appear in the registered version - http://www.clicktoconvert.com Abstract Hypocalcaemia is a commonly presented pathological condition in the grey parrot (Psittacus e. erithacus) although rarely reported in other psittacine birds. Signs in the adult birds are neurological ranging from mild ataxia to seizures responding rapidly to treatment with calcium or vitamin D3. Captive bred grey parrot chicks suffering from calcium metabolism disorders present as juvenile osteodystrophy with characteristic bowing of the long bones and pathological fractures in severe cases. The condition is comparable to rickets in poultry. This 3 year longitudinal study reports the effects of husbandry changes on the plasma ionised calcium, 25 hydroxycholecalciferol and parathyroid hormone concentrations in two groups of 20 sexually mature healthy grey parrots. The provision of a pellet diet with an increased vitamin D3 and calcium content significantly increased the plasma concentration of ionised calcium and 25 hydroxycholecalciferol over a seed fed control group. The provision of 12 hours daily artificial ultraviolet radiation (UVB 315-285nm spectrum) significantly increased the plasma ionised calcium concentration independent of the diet fed. In the seed group plasma 25 hydroxycholecalciferol concentrations significantly increased after the provision of UVB radiation but not in the pellet group. In a separate study with South American parrots (Pionus spp.) UVB radiation did not have a significant effect on vitamin D3 metabolism. -

Oooh man I was right! The trip started in paradisiacal surroundings on the island of Mahe, the largest of all islands that together form the Seychelles. Before embarking the Silver Discoverer , we planned some pre-tour birding. In the afternoon we made an outing to find the rare Seychelles White-eye, Seychelles Blue-Pigeon, and Seychelles Sunbird. Rapidly they were found, and good looks were enjoyed by all. In the evening after dinner we went out for probably the rarest and most difficult bird of the entire tour, the Seychelles Scops-Owl. For a long time we heard no response, but just before we decided to leave the designated spot we heard one quick rasping call. Soon after, we found the bird in full delight—just amazing! The enchanting Seychelles Sunbird has a very restricted range (photo M.Valkenburg) Our journey would take us from several Seychellois islands to Madagascar, visiting the world-famous Aldabra Atoll on the way, ending the trip with visits to Reunion and Mauritius. This adventure was one-of- a-kind, with our program visiting so many difficult to reach places where we had the chance of finding many of the world’s most hard-to-get endangered species. -
