The main objectives of the Nepal National Bird Red Data Book were to provide comprehensive and up-to-date accounts of all the bird species found in Nepal, assess their status applying the IUCN Guidelines at Regional Levels, identify threats to all bird species and recommend the most practical measures for their conservation.  It is hoped that the Bird RDB will help Nepal achieve the Convention on Biological Diversity target of preventing the extinction of known threatened species and improving their conservation status.  As population changes of Nepal’s birds have been studied for only a few species, assessments of species’ national status were mainly made by assessing changes in distribution.  Species distribution maps were produced for all of Nepal’s bird species except vagrants and compared to maps that were produced in 1991 using the same mapping system.  Of the 878 bird species recorded, 168 species (19%) were assessed as nationally threatened. These comprise 68 (40%) Critically Endangered species, 38 (23%) Endangered species and 62 (37%) Vulnerable species.  A total of 62 species was considered Near Threatened and 22 species Data Deficient.  Over 55% of the threatened birds are lowland grassland specialists, 25% are wetland birds and 24% tropical and sub-tropical broadleaved forest birds.  Larger birds appear to be more threatened than smaller birds with 98 (25%) non-passerine species threatened and 67 (14%) passerine species.  Habitat loss, degradation and fragmentation are the most important threats.  Other threats include chemical poisoning, over-exploitation, climate change, hydropower, invasive species, intensification of agriculture, disturbance, and limited conservation measures and research.  Measures to address these threats are described.  It was also concluded that re-assessments of the status of certain bird groups carried out every five years and the setting up of a national online system for storing and reporting bird sightings would be useful.

This paper aimed to fulfil the knowledge gap on the status of vagrants and rare birds of Nepal. Records of all Nepal’s bird species that were previously considered vagrants by the National Red List of Nepal’s Birds (2016) were collated and detailed with localities, dates and observers. Species recorded since 2016, including vagrant species, were also covered. A total of 92 species was assessed to determine if they were vagrants, that is species that had a total of 10 or less records. It was concluded that six species are no longer vagrant and we recommend these for national red list assessment. Nepal currently has a total of 71 vagrant species. In addition, four vagrant species have still to be accepted by the Nepal Rare Birds Committee before they can be officially included on the Nepal bird list. Nine species have so far only been recorded in the 19th century. Red-faced liocichla Liocichla phoenicea, was previously one of these, but was re-found In Nepal after the National Red List was published in 2016; it is a very rare and very local resident. Himalayan grasshopper-warbler Locustella kashmirensis is a recent split and now considered a full species (instead of a subspecies); it is probably an altitudinal migrant in Nepal. Despite great advances in our ornithological knowledge of Nepal, there is still high potential to find new species, especially of passerine birds and in the less explored parts of the country.

This paper is a review of the potential impacts of agriculture on Nepal birds. It includes an overview of agriculture in Nepal and the changes that have taken place between the early 1950s and 2007. Agricultural development has been sluggish, and has failed to keep pace with population growth. In recent years the yields of major food crops in Nepal have been lower than other South Asian countries and Nepal is now dependent on food imports. Land holding size per family and field sizes have both decreased markedly during the period. If hill regions are considered independently, all cereal crops yields have stagnated in the last 30 years and gains in production that have been made, have been due to increases in area of cultivation, at the expense of natural habitats: forests, wetlands and grasslands. Crop productivity in the hills has declined due to land degradation. Of the 28% of Nepal land that is degraded, 10% is poorly managed sloping agriculture terraces. As yields and production of cereal crops have fallen, many farmers have shifted to growing cash crops, to meet the demands of the increasing urban population and encouraged by government agricultural policies. Cultivation area, production and yields of some cash crops have significantly increased since 1964/65. Nepal’s livestock population is one of the highest in Asia and nearly every rural household keeps domestic animals resulting in widespread and serious problems of livestock overgrazing. The importance of agricultural habitats for Nepal birds is reviewed: 21% of bird species recorded in Nepal utilizes agricultural habitats for foraging at some season. The many ecological benefits of birds to agriculture and the damage caused by birds to agriculture are described: the former far outweigh the latter. Changes in agricultural practices (including changes in crops and crop production, impacts of livestock overgrazing) are having major and far-reaching impacts on natural habitats - grasslands wetlands and forests and their bird species; these changes and impacts are detailed and analysed. The increasing use of pesticides in Nepal, which is especially high on vegetable cash crops, the serious impacts of pesticides on birds and the environment and alternatives to pesticides are reviewed. Fertilizer use in Nepal and the damaging impacts of fertilizer over-use on birds and the environment are also reviewed. Recommendations to improve farming methods for the benefit of the environment are given. These include government measures to promote organic agriculture; government measures to expand the System of Rice Intensification and to encourage further use of Effective Microorganisms, both of which have significant benefits for environment, birds and farmers; field surveys to monitor bird populations and bird distribution on agricultural lands, and outreach and awareness-raising for farmers to apply best practice for sustainable environmentally friendly farming.DOI: 10.3126/on.v8i1.4339

Sukla Phanta Wildlife Reserve lies in the southwest corner of Nepal. It has been listed as an important bird area and a number of bird studies have been conducted here. The reserve is an important refuge especially for many grassland birds, several of which are globally threatened. The high, total of 15 globally threatened and 13 near-threatened bird species occur in Sukla Phanta. Some of the bird species reach their world limit of distribution at Sukla Phanta. Of all the habitats found in Sukla Phanta, grassland is the most important. Conservation and management of grasslands that are sympathetic to bird populations are urgent at Sukla Phanta.
