  • Bird collisions with glass are a substantial source of human-caused avian mortality. It has been estimated that between 100 million and 1 billion birds die in collisions with windows every year, and bird-window collisions can have a particularly serious impact on populations because glass is dangerous for strong, healthy, breeding adults. The purpose of this study are to address the bird-window collision issue and to provide suggestions for bird-safe development by reviewing precedent studies on bird collision and analyzing bird-friendly design guidelines. Typically reflections of the sky, clouds or trees on glass, green plants in lobbies, and lights attract and confuse both migrating and resident birds. Therefore birds fatally fly into the glass because they do not recognize that reflections are false and that glass is a barrier. Many cities such as Toronto, Chicago and New York have made efforts on reducing the bird collision by encouraging the creation of environmentally conscious and bird-safe buildings. The USGBC also introduced a bird-safety credit as part of its environmental certification process, called LEED. The results of the study presented that architects and builders can help reduce or prevent bird from collisions in both new construction and existing structures with creative use of design elements. The measures to reduce bird collisions include using glass with an embedded pattern, opaque or translucent films, decals, dot patterns, awnings, louvers, and grilles. Turning off lights after midnight during the spring and fall migrations can be part of the solution as well. In order to reduce bird mortality, the most important thing is to generate awareness of the issue among designers, builders, as well as the public. Also local governments need to develop bird-friendly design guidelines and planning mechanisms to encourage bird-safe development and building operation.

  • This study was conducted to clarified the relationship between bird community and forest structure and present the counterplan for protection and management of bird community from February 1993 to July 1995 at deciduous and coniferous forest within Mt. Nam area, Seoul, Korea. DBH distribution has not significant differences in each study site. Deciduous forest had more foliage coverage in all layers than coniferous forest. Total 41 species of birds, which were 16 species of resident, 14 species of summer visitor, 4 species of winter visitor, and 7 species of passage migrant were recrded in two study sites. Leaf use rate of birds was increased the increase of coverage. The number of breeding species and pairs, breeding density, and diversity index were greater in deciduous forest than coniferous forest. The number of species and pairs on bush-nesting and foraging guild were greater than other guilds. And the nuber of species and pairs on hole nesting guild were the fewest in nesting guild. Use rate of artificial nests for improvement of habitat quality was greater in coniferous forest than deciduous forest. Maintenance of bush layer, increase of coverage and leaf layer diversity, supply of artificial nests, management of large trees, and control of natural enemy were necessary for protection and management of bird community in Mt. nam area.

  • Bird species (BS) of the Nakdong River estuary (NRE) were selected to suggest conservation and management strategies, taking habitats and major threats into consideration. Five BS (Cygnus spp., Calidris alpina, Sterna albifrons, Fulica atra, and Anser fabalis) were selected following analysis of their dominance, national importance, seasonality, taxonomic group, and distribution within the NRE. The BS comprise two winter birds, one summer, one passage bird, and one resident bird. They can also be classified into four taxonomic groups: two under ducks and geese (Anatidae), and one each under gulls (Laridae), shorebirds (Scolopacidae), and diving birds (Rallidae). The results show that BS could be a useful tool in guiding estuary management because their habitats are clearly distinct, and include important areas of the NRE. A reduction of feeding and resting places-such as tidal flats, Scirpus planiculmis habitat, and agricultural farmland-and climate change are major threats to BS, therefore countermeasures to such threats should be considered in future estuary management plans.

  • The theory of island biogeography has influenced strongly on the conservation and management issues of species diversity in the islands. The theory has not limited to islands in the ocean, but expanded to isolated and fragmented areas in the forests and urban. This study has a rare opportunity to explore the species diversity and abundance of birds in the islands of Korea. A total of 151 islands in the west and south areas in the Korean peninsula were examined. The number of species and the area of islands were highly significant (P<0.000) and the number of species and the distance from the mainland showed not so strong relationship. This indicated that bird species diversity has more influenced by the size of the islands not the distance. This can be from the study species of birds that can fly long distance, and also natural characteristics of migratory and resident status. Species-area curve showed that the z-value was 0.21 indicating the area and the bird species are strongly correlated. The long-term monitoring of bird species presence in the islands should be followed for a proper management plan.

  • We have conducted a verification test of correlation between bird community indices and bird sound recording results in order to use the equipment which deals with the automatic sound collecting system, the song meter. The study areas include four sites which are Gombaeryoung and Zochimryoung in Jeombongsan Mountain and Jookryoung and Gochiryoung in Sobaeksan National Park. We collected the bird sound data five times using a sound recorder and field survey results in the same place of the study site. As a result of the sound recording from the field survey, the species recorded by three researchers of sound analyst include common resident species or species which have a relatively conspicuous call and song. On the contrary, the species recorded by only one researcher are a relatively rare or inconspicuous species or was familiar with the personal experiences of each researcher. The number of species recorded by only one researcher totaled fourteen species (36.8 %), and that of two researchers totaled twelve species (31.6 %), and that of three researchers totaled twelve species (31.6 %). The correlations of the number of species among three researchers was not significant in some results, but the sum or maximum count of the number of species was useful to estimate a significant correlation between the result of researchers and the indices of field surveys. As a result of correlation analysis by using sound recordings, the maximum number of species among the three researchers significantly correlated with the number of species, the species diversity index and the species abundance index in the field survey at the same site, however it did not correlate with the number of individuals and species evenness index. As a result of sound analysis collected from the stationary sound recording system; song meter, the number of frequencies in bird songs and calls correlated with the number of species in the field survey at the same site. The number of calls and songs decreased as time went by. Finally, we could test the active time range and change the activity strength by using a sound recording system. In particular, that sound recording system is able to collect data in same time and site, so it is expected so that the equipment not only replenish a shortage of researchers and survey periods in field research in a short term monitoring survey, but also be able to acquire statistical objectivity.

  • For this paper, a study targeting 9 forest patches in Dangjin to suggest for the wild birds, was conducted. The correlation between the emergence of wild birds and the forest vegetation was analyzed, and the patterns of forest vegetation for the improvement of species diversity were suggested by classifying wild birds and foraging guild by the type of forest vegetation. As for the characteristics of the wild birds emerged, more species and bigger population appeared in the vegetation type of mixed stand forest where the natural deciduous broadleaf trees and evergreen needleleaf trees coexisted in the large scale vegetation area. Thus, it was known that the advent of summer migratory birds and resident birds were affected the most by forest patches and vegetation types. As for foraging guild, the larger the forest paches the more the species and the population of the wild birds inhabiting in shrubs and bushes.

  • Wetlands are very critical for the conservation of aquatic ecosystems, while also serving as the breeding/ nesting/ resting grounds for water birds. Generally, wetlands support both resident and migratory birds, thus serving as connecting dots in the global flyways. The Rajasthan state of India has two Ramsar sites (Keoladeo National Park and Sambhar Lake) and many other water bodies/wetlands. However, most of these areas are segregated in the eastern, southeastern, southern, and northern parts. In the western part of Rajasthan, where lies the Great Indian or Thar desert, there are no such reported prominent wetlands drawing attention towards a substantial number of resident and migratory water birds. The author is an Indian Forest Service officer, who was posted in the Thar Desert region and during that time had identified a hidden wetland in the desert landscape. This study deliberates on the wetland location and its faunal diversity with prospects of developing the area as a proper wetland conservation zone. India is a signatory to the Central Asian Flyway of migratory species and serves as an important member in terms of having significant wetlands and reported migratory birds count. The need of preserving and bring the arid zone's hidden wetlands to the forefront can serve as an important tool to conserve water birds and comply with worldwide bird migration conservation efforts.
