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).

Two species in this group—the European starling Sturnus vulgaris and the common Myna Acridotheres tristis—now occur on continents and islands around the world following human-mediated introductions, and the entire clade is generally notable for being highly social and dispersive, as most of its species breed colonially or move in large flocks as they track ephemeral insect or plant resources, and for associating with humans in urban or agricultural land- scapes. Our reconstructions were based on substantial mtDNA (4 kb) and nuclear intron (4 loci, 3 kb total) sequences from 16 species, augmented by mtDNA NDII gene sequences (1 kb) for the remaining 10 taxa for which DNAs were available only from museum skin samples.

  • 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.

  • Myna Matters - Notes on Introduced Passerines in Western Samoa
    SHORT NOTE More myna matters - notes on introduced passerines in Western Samoa We visited Western Samoa at the following times: 26 July to 15 August 1991 (BJG), 9 August to 21 September 1991 (JRH and TGL) and 2 1 March to 4 April 1992 (TGL). Among the abundant Jungle Mynas (Acrrdotheresfuscus) in Apia we saw a few Common Mynas (A. tristis), as had Beichle (1989), and we made some counts of the relative abundance of the two species. During our visits we travelled along all the main roads of both islands. We mapped the sites at which we saw Jungle Mynas and Red-vented Bulbuls (Pycnonotus cafer), as a bench-mark for future observations. A review of previous records of mynas in Western Samoa has disclosed a report (Green 1965) that establishes an earlier date of introduction than was noted by Beichle (1989). Jungle Myna Mynas were first reported in Western Samoa by Green (1965) as "Introduced Mynah Acridotheres tristis?", and Dhondt (1976) as A. tristis. However, these birds were almost certainly Jungle Mynas because only Jungle Mynas were seen by Beichle during extensive field work from 1977 to 1984 (Beichle 1989) and by Watling in January 1978 (Watling 1978b). The increase of the Jungle Myna in Western Samoa may be traced chronologically as follows: July 1957. Not recorded by Keith (1957) who spent three days on 'Upolu. Not mentioned in the review by Ashrnole (1963). May-June 1965. Green (1965) often saw mynas in Apia but not beyond the town area. September 1970. Not recorded by DuPont (1972) and two companions, who made a point of recording species not previously reported.

We flew from Delhi to Guwahati, located in the far northeast of India. A long drive later through the hectic traffic of this enjoyable country, we arrived at our lodge in the evening. (Photo by tour participant Robert Warren) We enjoyed three full days of the wildlife and avifauna spectacles of the famous Kaziranga National Park. This park is one of the last easily accessible places to find the endangered Indian One-horned Rhinoceros together with a healthy population of Asian Elephant and Asiatic Wild Buffalo. We saw plenty individuals of all species; the rhino especially made an impression on all of us. It is such an impressive piece of evolution, a serious armored “tank”! On two mornings we loved the elephant rides provided by the park; on the back of these attractive animals we came very close to the rhinos. The fertile flood plains of the park consist of alluvial silts, exposed sandbars, and riverine flood-formed lakes called Beels. This open habitat is not only good for mammals but definitely a true gem for some great birds. Interesting but common birds included Bar-headed Goose, Red Junglefowl, Woolly-necked Stork, and Lesser Adjutant, while the endangered Greater Adjutant and Black-necked Stork were good hits in the stork section.

  • Hand-Raising and Rehabilitation of Mynas
    Hand-raising and rehabilitation of mynas Corina Gardner Hill mynas David Lim Introduction Mynas are average sized (about 22-28 cms) passerine birds which belong to the family of starlings, Sturnidea. The term ‘myna’ is commonly used to refer to starlings in India. Mynas are commonly distributed throughout Southern and Eastern Asia. These birds have duller plumage and are more terrestrial compared to other members of the starling family. 1 Rehabber’s Den © 2012 Hand-raising and rehabilitation of mynas Common myna Acridotheres tristis The common myna is widely distributed throughout India and Asia and has also been introduced to many parts of the world. The species lives in woodlands and near human habitations. They have brown plumage, a black head, throat and breast, while the bill and legs are yellow. They also have a distinctive yellow patch behind the eyes. They are omnivorous birds and will scavenge for just about anything including discarded scraps, insects, seeds, grain and fruit. They roost in large trees and build their nests in walls and rooftops of buildings. Common myna Tris Jungle myna Acridotheres fuscus Jungle mynas are found in and around the Indian subcontinent. They have brownish grey plumage, a tuft of feathers on their heads, white patches on their 2 Rehabber’s Den © 2012 Hand-raising and rehabilitation of mynas primaries and a white tipped tail.

  • 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.

ABSTRACT.--Fromour reviewof articlespublished on diurnal and nocturnal birds of prey occurringin Africa and the western Indian Ocean islands,we found most of the information on their breeding biology comesfrom subtropicalsouthern Africa. The number of published papers from the eastAfrican tropics declined after 1980 while those from subtropicalsouthern Africa increased.Based on our KnoM- edge Rating Scale (KRS), only 6.3% of breeding raptorsin the eastAfrican tropicsand 13.6% of the raptorsof the Indian Ocean islandscan be consideredWell Known,while the majority,60.8% in main- land east Africa and 72.7% in the Indian Ocean islands, are rated Unknown. Human-caused habitat alteration resultingfrom overgrazingby livestockand impactsof cultivationare the main threatsfacing raptors in the east African tropics, while clearing of foreststhrough slash-and-burnmethods is most important in the Indian Ocean islands.We describeconservation recommendations, list priorityspecies for study,and list areasof ecologicalunderstanding that need to be improved.
