Abstract:

1. Colombia with 1941 known recorded bird species is one of the most species rich countries in the world. Efforts are necessary to conserve, study and promote sustainable use of this important taxonomic group throughout Colombia's vast territory.2. In an ideal world, informed decisions that are based on sound scientific information should be likelier to have successful outcomes. Nevertheless, there are barriers that make it difficult to access and use information in a timely fashion. Those same barriers impede the study, conservation, and sustainable use of birds in Colombia. On the other hand

Abstract:

A challenging problem in the field of avian ecology is deriving information on bird population movement trends. This necessitates the regular counting of birds which is usually not an easily-achievable task. A promising attempt towards solving the bird counting problem in a more consistent and fast way is to predict the number of birds in different regions from their photos. For this purpose, we exploit the ability of computers to learn from past data through deep learning which has been a leading sub-field of AI for image understanding. Our data source is a collection of on-ground photos take

Abstract:

Land-use change from a rubber plantation into the ITERA campus area causes an ecological transition. The components of ecology affected are vegetation and wildlife (bird). Geographic information systems can be used to assess the condition of vegetation and its relation to the ecological component. This study analyses bird diversity, vegetation condition through the NDVI value distribution, and then analyses the bird distribution based on vegetation condition. Observation in transect is the method for collecting bird distribution data. Analyses of vegetation condition was carried out based on N

Abstract Wetland bird species have been declining in population size worldwide as climate warming and land-use change affect their suitable habitats. We used species distribution models (SDMs) to predict changes in range dynamics for 64 non-passerine wetland birds breeding in Europe, including range size, position of centroid, and margins. We fitted the SDMs with data collected for the first European Breeding Bird Atlas and climate and land-use data to predict distributional changes over a century (the 1970s–2070s). The predicted annual changes were then compared to observed annual changes in

During variable distance point counts a stationary observer records the species and distance for all birds detected during a fixed time interval. Such counts, repeated throughout the area of interest, can be used to estimate bird density so long as the following assumptions are made: (1) the distribution of birds is unaffected by the observer; (2) observers are certain of detecting near birds; (3) there is no error in measurement or estimation of distances; and (4) birds are stationary. Data collected during the present study indicated that at least two of these assumptions are not satisfied:

Human land-use effects on species populations are minimized in protected areas and population changes can thus be more directly linked with changes in climate. In this study, bird population changes in 96 protected areas in Finland were compared using quantitative bird census data, between two time slices, 1981–1999 and 2000–2009, with the mean time span being 14 years. Bird species were categorized by distribution pattern and migratory strategy. Our results showed that northern bird species had declined by 21 per cent and southern species increased by 29 per cent in boreal protected areas dur

Abstract:

The island of Puerto Rico supports a diverse assemblage of breeding birds, including 16 endemic species (Raffaele et al. 1998), and provides critical wintering habitat for many North American migratory birds (Wunderle and Waide 1994). Despite being a hotspot of avian biodiversity, spatially extensive data on the distribution and abundance of birds on the island are scarce. Breeding-bird assemblages were sampled by the North American Breeding Bird Survey from 1997–2007 (Sauer et al. 2013), but comparable primary data are not available for bird assemblages present during the boreal winter.

This research aims to determine the use of canopy strata for birds and determine bird activity based on the use of canopy strata in Lorulun Village, Wertamrian District, Tanimbar Islands Regency. Bird watching in Lorulun Village uses the point count method which is made in five plots. To collect vegetation structure data vertically, namely using a canopy stratification approach, the technical implementation is by recording the types of birds found. The data obtained in this research was then analyzed descriptively qualitatively and quantitatively. The results of the research carried out were t

Birds are the biological indicators in an environment since the birds belong to the top level of the food chain in an ecosystem. Ecological changes cause changes in a number of breeding and wintering of bird populations. Bird habitat and many bird species are inseparable and helpful to mankind in various ways and their presence is very essential to restore local biodiversity. The present study on avifauna was carried out around Kotwal reservoir, Morena district of Madhya Pradesh, India. A total of 104 species were found belonging to 17 Orders and 40 families.

The sustainability of birds is also influenced by the dynamics that occur in nature. Conditions like this can be studied by looking at various patterns and habits such as distribution patterns, activities, and other habits. In a habitat type, the same species can fill different vertical spaces. This is also related to the components that support bird life, starting from shelter, cover, feed, and other habitat components. UB Forest as a bird habitat is managed by Universitas Brawijaya.

Current data show that Ethiopia has 18 endemic bird species. Some of these species are distributed in different regions of Ethiopia (Yellow-fronted Parrot, Abyssinian Longclaw, Wattled Ibis, Blue-winged Goose, Abyssinian Catbird). In contrast, some species are restricted in a few areas (Red-billed Pytilia, Yellow-throated Serin, Salvadori’s Serin). The assemblages of endemic birds diminish over time du
