Preserve birds in their natural NZ habitat and save their “Wild Musick”.

The Wild Musick framework has been created to support the Ministry of Business, Innovation and Employment (Tourism) NZ, Department of Conservation, Ministry of Conservation, and Ministry of Youth Development. It works to encourage the youth, and families in saving birds and conserving the biodiversity of New Zealand avian population. The solution offers the following direct use cases : 1. Ministry of Business, Innovation and Employment (Tourism) a. Creation of new walking trails along areas of high bird density. b. Promoting bird watching and bird sounding trips. c. Aligning the tourism season with bird migration and seasonal population variation of birds. d. Promoting bird watching as a sport. e. Family trips encouraged to record bird sounds and feeding them to the Wild Musick web service. 2. Ministry of Conservation (Bio Conservation) a. Pest population has an inverse relationship to the bird population in a geographic area. The Wild Musick framework can assist in decreasing the pest population in an area supporting other programs working in conjunction with saving birds. b. Saving the avian population leads to the maintenance of the ecological balance in the Aotearoa region. c. Identification of unusual birds migration in specific areas. d. Identification of bird songs from bird calls and identifying the breeding season and perhaps preventing human intervention during the season. e. Identifying bird’s behaviour based on their songs/calls. f. Identify the population density of the endangered birds species. 3. Ministry of Youth Development a. Identify the bird sounds in the wild on youth trips. b. Respond to a bird call for help, if we can isolate the bird sound c. Gamify the application and ask the youth (children as well as youth) when they go wit

Simulating anthropogenic impacts to bird communities in tropical rain forests

We used an aggregated modelling approach to simulate the impacts ofanthropogenic disturbances on the long-term dynamics of faunal diversityin tropical rain forests. We restricted our study to bird communities eventhough the approach is more general. We developed a model calledBIODIV which simulated the establishment of hypothetical bird speciesin a forest. Our model was based on the results of a simple matrix modelwhich calculated the spatio-temporal dynamics of a tropical rain forest inMalaysia. We analysed the establishment of bird species in a secondaryforest succession and the impacts of 60 different logging scenarios on thediversity of the bird community. Of the three logging parameters(cycle length, method, intensity), logging intensity had the most servereimpact on the bird community. In the worst case the number of bird specieswas reduced to 23% of the species richness found in a primary forest

Seasonal changes in avian communities living in an extensively used farmland of Western Poland

To study the seasonal changes in avian communities, we collected data in an extensively used farmland in Western Poland during 2006-2013. Generalized additive mixed models were used in order to study the effects of seasonality and protected areas on the overall bird species richness. A similarity percentage analysis was also conducted in order to identify the species that contribute most strongly to dissimilarity among each bird according to the phenological season. Furthermore, the differences in bird communities were investigated applying the decomposition of the species richness in season, trend, and remainder components. Each season showed significant differences in bird species richness (seasonality effect). The effect of the protected areas was slightly positive on the overall species richness for all seasons. However, an overall negative trend was detected for the entire period of eight years. The bird community composition was different among seasons, showing differences in terms of dominant species. Greater differences were found between breeding and wintering seasons, in particular, the spatial pattern of sites with higher bird richness (hotspots) were different between breeding and wintering seasons. Our findings showed a negative trend in bird species richness verified in the Polish farmlands from 2006. This result mirrors the same negative trend already highlighted for Western Europe. The role of protected areas, even if slightly positive, was not enough to mitigate this decline process. Therefore, to effectively protect farmland birds, it is necessary to also consider inter-seasons variation, and for this, we suggest the use of medium-term temporal studies on bird communities’ trends

A Theoretical Framework for the Analysis of the West Nile Virus Epidemic

We present a model for the growth of West Nile virus in mosquito and bird populations based on observations of the initial epidemic in the U.S. Increase of bird mortality as a result of infection, which is a feature of the epidemic, is found to yield an effect which is observable in principle, viz., periodic variations in the extent of infection. The vast difference between mosquito and bird lifespans, another peculiarity of the system, is shown to lead to interesting consequences regarding delay in the onset of the steady-state infection. An outline of a framework is provided to treat mosquito diffusion and bird migration.Comment: 12 pages, 9 postscript figure

Urbanization, environmental stabilization and temporal persistence of bird species: A view from Latin America

Background. A scarcely studied consequence of urbanization is the effect of temporal stabilization of the environment on bird communities. This alteration is thought to dampen environmental variations between day and night, seasons and years, promoting a temporal persistence of bird composition in urban areas. The aim of this study was to review current evidence of temporal stabilization of biotic and abiotic factors in urban environments and the potential effects of such stabilization on temporal variation of bird species presence at different temporal scales. Methods. I selected the literature by searching published articles and book chapters using Scopus and Google scholar. I only included articles that compared the temporal variation of bird composition or resources between different levels of urbanization. Results. In general, there is evidence of temporal stabilization of abiotic and biotic factors at the three time scales considered. At the diurnal scale, the main factor considered was artificial light in the context of light pollution. At the seasonal and interannual scales, several case studies found a smaller temporal variation of primary productivity in urban than in natural and rural areas. Bird species composition showed more stabilization in urban environments at the three temporal scales: (1) several case studies reported bird activity at night, associated with artificial light; (2) studies in urban parks and along urbanization gradients showed smaller seasonal variation of bird composition in the more urbanized areas; and (3) in general, case studies along urbanization gradients showed smaller interannual variation of bird composition in the more urbanized areas, although some studies showed no relationships or opposite trends than expected. Discussion. The published evidence suggests that urban areas dampen the natural cycles at several temporal scales. The stabilization of biotic and abiotic factors, such as light, temperature, food and habitat structure, is desynchronized from natural diurnal, seasonal and interannual cycles. However, there is a dearth of long-term comparisons of bird composition and studies that simultaneously analyze the relationship between resources and bird composition stabilization at the seasonal and interannual scales. More research is needed in the Southern hemisphere, where there is a lack of studies dealing with the seasonal and interannual variations of primary productivity along urbanization gradients and nocturnal activity of bird species. A future research agenda should include differentiation of spatial and temporal homogenization of avifaunas.Fil: Leveau, Lucas Matias. Consejo Nacional de Investigaciones Científicas y Técnicas.

PRELIMINARY BASELINE SURVEY OF AVIFAUNAL DIVERSITY IN JIMMA ZONE, SOUTH-WESTERN ETHIOPIA

Multidimensional poverty, which is deeply-rooted within least-developed African countries like Ethiopia, is forcing local people to heavily rely on natural resources for their subsistent livelihoods. As a result, remaining wilderness areas in tropical Africa which support huge but little known biological diversity, are subject to extensive habitat loss, fragmentation and degradation in turn causing loss of plant and animal species and ecosystem services provided by them. Coffee forest fragment within the Jimma Zone of Ethiopia cannot be expected to be an exception to such scenario. Taking this persistent problem into consideration, we carried out a preliminary survey of bird biodiversity in selected areas of Jimma Zone during a short term bird ringing training held from Sept. 30 to Oct. 20, 2008. The main objective of the survey was to identify and document bird species of Jimma Zone, Southwestern Ethiopia, for further in-debth ornithological studies. Survey data were collected through exhaustive observations in and around 10 coffee forest fragments in Garuke, one fragment in Eladale, one urban area site in Jimma town and in scrubland vegetation around Gilgel Ghibe hydropower reservoir, Jimma Zone, Southwestern Ethiopia. In addition, five mist-nets were employed to capture understory forest birds in two purposively selected coffee forest fragments. Mist nets were opened at 5:50 A.M. and checked every 30 minutes until they were closed at 12:00 A.M. Over 196 bird species were identified during this survey and of these, 41 individuals belonging to 20 species were captured in Garuke and 23 individuals of 9 bird species in Eladale. Montane white-eye (Zosterops poliogastrus) followed by Olive sunbird (Nectarinia olivacea), Abyssinian slaty-flycatcher (Melaenornis chocolatinus) and Rupell’s robinchat (Cossypha semirufa) were the most frequently captured bird species. Of the sites surveyed, Gilgel Ghibe hydropower reservoir had strikingly highest bird species diversity. We approached the reservoir almost in a constant site near Bulbul Kebele (the smallest administrative unit in Ethiopia) and recorded over 115 bird species within about 300 meters distance! We learnt that this area was an important and most appropriate site to see a number of migrant and resident species as well as to undertake future bird ringing activities. We believe that the result of this survey will contribute much for the preparation of a comprehensive bird species checklist for Jimma Zone that could serve as important baseline information for more focused future ornithological investigations in the area so as to promote bird conservation through ecotourism activities and improve the livelihood of local people
