The plight of indigenous birds on oceanic archipelagoes often makes depressing reading, as the author points out in his forthcoming book, Naturalized Mammals of the World. Habitat destruction by domestic stock and predation by accidentally introduced rats and mice are the major causes. In Bermuda this discouraging trend has been reversed by the successful rehabilitation of two species within the space of a quarter of a century.

This research project works to analyze and diminish the major threats to the Golden Eagle species through developing efficient and effective conservation techniques and introducing these advancements into the Kingston, Ontario habitat. We propose a partnership with the Kingston Field Naturalists (KFN), a community group with an active mandate in the preservation and conservation of wildlife and natural habitats. Many of their current projects involve at-risk bird species, and they are well equipped to aid in the successful development and implementation of this initiative. There are a few factors that affect the livelihood of Golden Eagles. Wind turbines, pesticides and power lines are some parts of an urban setting that cause disturbance to these creatures. Other vulnerabilities include habitat destruction, limited food availability and human killings to prevent preying on livestock. Some conservation techniques that are successful in managing Golden Eagle populations around the world include the use of bird sensitivity maps and the implementation of adaptive-management frameworks during community planning. Sensitivity maps are formulated taking into account foraging range, collision risk and sensitivity to disturbance (Bright et al., 2008), while adaptive-management frameworks limit recreational activities near known nesting areas (Fackler et al., 2010). By implementing and adapting strategies put in place in countries like Ireland and around the world we hope to reintroduce a sustainable population of Golden Eagles in Ontario, specifically within the Kingston area. This can be achieved through donation of Golden Eagle chicks from areas in Canada in which this bird is common.

In pantomime the Dame and comics, and to a lesser extent the immortals, are positioned between the world of the audience and the world of the story, interacting with both, forming a link between the two, and constantly altering the distance thus created between audience and performance. This position allows these characters to exist both within and without the story, to comment on the story, and reflexively to draw attention to the theatricality of the pantomime event. In this article, Millie Taylor concludes that reflexivity and framing allow the pantomime to represent itself as unique, original, anarchic, and fun, and that these devices are significant in the identification of British pantomime as distinct from other types of performance. Millie Taylor worked for many years as a freelance musical director in repertory and commercial theatre and in pantomime. She is now Senior Lecturer in Performing Arts and Music Theatre at the University of Winchester. An earlier version of this article was presented at the Conference on Arts and Humanities in Hawaii (2005), and an extended version will appear in her forthcoming book on British pantomime. Her research has received financial support from the British Academy.

Abstract The red-billed quelea is a small weaver bird native to sub-Saharan Africa and renowned for its attacks on small-grain crops within Africa. It is the most numerous bird species in the world, with peak post-breeding population estimated at 1,500,000,000. The red-billed quelea is mainly granivorous, except when feeding its chicks insects or when eating insects prior to migration or breeding, and it relies on a supply of grass seeds to survive. When unable to find grass seeds or when opportunities arise, quelea will attack crops. It is a major pest throughout much of sub-Saharan Africa and can cause significant economical losses.

Bagmati River is considered as a potential conservation area in terms of the bio-diversity conservation due to its unique and diversified habitat distribution. Due to various causes, the river is being polluted and hence habitat degradation rate is increasing. As a consequence, the direct effect is seen on birds inhabiting there. Aiming the assessment of bird's diversity, one year survey was conducted in Bagmati River from Tilganga Bridge to chobhar Gorge Bridge (here after termed as Bagmati river corridor) by applying the point count method .In the total enumeration, 100 of birds species were recorded among which 7 are listed in CITES appendix. The bird species that are regarded as globally threatened are not recorded in the study area. In this report, some potential patches in the study area, are described as hot spots, considering the higher probability of recording maximum number of birds species. The public voice is also collected to find out the public perception on the present status of birds of Bagmati river corridor using the questionaire method. Some causes of habitat destruction and some potential conservation measures are also mentioned.

SummaryThe declining-population paradigm holds that small populations are particularly vulnerable to anthropogenic influences such as habitat destruction, pollution and species introductions. While the effects of particular stressors, such as parasitism, may be unimportant in a large, healthy population, they can be serious and even devastating in situations characterised by a restricted geographic range, or by fragmented or reduced population sizes. We apply this idea to nest parasitism of threatened Neotropical bird species that exist in small populations, focusing on dipteran nest parasites in the genusPhilornis. We review the literature onPhilornisparasitism exerting negative pressure on bird populations that have become small and isolated due to human actions and present a new case ofPhilornisparasitism of a threatened hummingbird species. Our aim is to raise awareness about the exacerbating effect that nest parasites can have on small and declining bird populations; especially when biological information is scarce. The five reviewed cases involve two species of Darwin’s Finches in the Galápagos Islands attacked by the invasiveP. downsi, two species of hawks on islands in the Caribbean attacked by the nativeP. piciandP. obscura, and the Yellow CardinalGubernatrix cristatain southern South America attacked by an unknownPhilornisspecies. We also present new documentation of parasitism of a threatened hummingbird species in mainland Ecuador by an unidentifiedPhilornisspecies. We recommend more field studies to determine the presence of nest parasites in bird populations worldwide to improve understanding how nest parasites affect bird fitness and population viability and to allow time to act in advance if needed. Parasitism byPhilornismay represent a severe mortality factor in most already threatened bird species, putting them at greater risk of extinction. Therefore, parasitism management should be included in all threatened species recovery plans.

Few foreign visitors have known the United States as well as Michel Crozier. For that matter, few Americans do. When he speaks about “the trouble with America” it behooves us to listen and to mark his words. The Washington Post announced his forthcoming book with a two-column headline, “America, An Adult Nation Can’t Afford Your Illusions,” and that seems to be a fair synopsis. “This is now the time” writes Crozier, “for America to learn again, to forget its dreams of innocence and superiority, to become humble enough to accept that there are lessons to learn from the rest of the world and from the facts” (Crozier, 1984, 5). America, it appears, is a retarded adolescent.

Coasts were one of the main places of residence for human beings through the history. From the emergence of civilization to now, the human beings used coastal zone as a best place for residence. However, in early 21 century, almost two-third of people in the world (i.e. 3/7 billion people) lived in the 60 km of sea sideline. Therefore, some problems threaten human communities, includes soil erosion, changes in coastline, coastal habitat destruction, drying or polluting underground waters, and creating dangerous situation for hygiene and health in order to lack of insufficient repulsing waste and sewage. Thus, according to these problems, the integrated coastal zone management (ICZM) was considered as a main way for solving the environmental problems. This chapter follows the goal that is related to the ICZM, particularly in Iran, after investigating the problems in the coastal region.

Illness tends to affect function in frail elderly patients, and these patients have limited capacity to spontaneous physical recovery. This chapter argues that rehabilitation should be firmly integrated into health services for elderly people and not separated from conventional medical treatment. Further, we argue that these two aspects should be handled simultaneously. Rehabilitation is goal-based, and setting goals in cooperation with patients is a crucial condition for successful rehabilitation, and for its evaluation, clinically as well as scientifically. The World Health Organization International Classification of Functioning, Disability, and Health (ICF) is recommended as a conceptual framework for assessment, goal setting, and evaluation in rehabilitation. Rehabilitation can be considered an iterative rather than a linear process, with regular evaluations and renegotiation of goals playing a crucial role in the efficacy of such a process.

This study documents aquatic and terrestrial/riparian biodiversity in an anthropogenically disturbed Ramsar site, the Ghodaghodi Lake complex, in the Western Nepal surveyed during the summer season (March-April) of 2007. The study site comprises three major interconnected lakes: Ghodaghodi (138 ha), Nakharodi (70 ha), and Bainshwa (10 ha). Five transect lines for aquatic macrophytes and three transect lines and 37 sampling plots were laid to sample terrestrial/riparian plants, birds, and animals. Five sample plots were established for fish and aquatic bird. A total of 45 species of aquatic macrophytes, 54 species of terrestrial/riparian vegetation, 19 fish species, 41 bird species, 17 mammals (endangered and vulnerable), and 5 reptiles (critically endangered, vulnerable, and near threatened) were recorded at the lake complex. Local people have used most of the aquatic and terrestrial plants for different purposes while many of the potential medicinal plant species were still untapped. Persistent anthropogenic threats, like excessive harvesting and poaching, habitat destruction—population pressure, forest fragmentation, siltation, fertilizer and pesticide seepage, water pollution, overgrazing, and unmanaged irrigation system found over the lake complex, endangered the existing biodiversity. The suggested remedial measures are further exploration of medicinal potential, prioritization of in situ biodiversity conservation strategies, and implementation of awareness program at local level against anthropogenic threats.
