Résumé :

An information system (IS) BIRDS2 has been developed for storing and analyzing data obtained by monitoring the behavior of birds on the territory of wind power plants (WPPs) using the route accounting method. The program code is compiled on the basis of Windows Forms technology in the Microsoft Visual Studio Community 2019 software development environment. The operation of the program was tested by comparing the results of monitoring bird migration on the territory of the Primorsk-1 wind farm with known literature data. The sample size of registered birds used for analysis consisted of 8927 bi

Résumé :

Flight is a unique adaptation at the core of many behaviours in most bird species, whether it be foraging, migration or breeding. Birds have developed a wide diversity of flight modes (e.g. flapping, gliding, soaring, hovering) which involves very specialized behaviours. A key issue when studying flight behaviours is to understand how they develop through all the ontogenetic stages of birds, from the embryo to the flying adult. This question typically involves classical debates on animal behaviour about the importance of maturation and experience. Here, we review the literature available on th

Résumé :

The development of photovoltaic (PV) utility-scale solar energy (USSE) in the desert Southwest has the potential to negatively affect birds through collision mortality. Based on early patterns in fatality monitoring data, the lake effect hypothesis (LEH) was developed and suggested that birds misinterpret PV solar panels for water. As the LEH was only recently defined and inference beyond bird mortality is limited, our research objective was to examine the species composition, abundance, and distribution of live and dead aquatic habitat birds at five PV solar facilities and paired reference ar

Bird skeletons exhibit remarkable modifications that allow for flight. The most distinguishable features are the fusion of the bones in the hand, feet, and pelvis into composite rigid and bony structures.

Here, we describe an Early Cretaceous bird (120 Mya) that has fully fused alular-major metacarpals and pelvis.

Although nowhere stated in the expedition account, the aim appears to have been to acclimatise the birds to a German environment for the purpose of falconry. Five birds were captured and transported to Germany, four juveniles from a nest near Godhavn and an adult bird from near Uummannaq. After a brief sojourn at Riddagshausen the birds were transferred t

Résumé :

AbstractBiodiversity indicators are essential for monitoring the impacts of pressures on the state of nature, determining the effectiveness of policy responses, and tracking progress towards biodiversity targets and sustainable development goals. Indicators based on trends in the abundance of birds are widely used for these purposes in Europe and have been identified as priorities for development elsewhere. To facilitate this we established bird population monitoring schemes in three African countries, based on citizen science approaches used in Europe, aiming to monitor population trends in c

Résumé :

AbstractAbstract This review covers research linking foraging habitat quality for birds to livestock management in lowland farmland. Based on this research we propose a framework for predicting the value of grazing systems to birds. This predictive framework is needed to guide the development of agri-environment measures to address farmland bird declines in pastoral areas. We show that the exacting requirements of declining granivorous birds pose the greatest challenges, while the needs of soil invertebrate feeding species are more easily met.

Abstract. City development changes the landscape and has been claimed to pose threat to the survival of birds that heavily relies on healthy forest ecosystem. As such, this study assessed the effect of land-use land-cover (LULC) changes due to sub-urbanisation on birds’ community using geostatistical method. In this study, geostatistical analyses, namely Kernel Density and Ordinary Least Square (OLS), were executed to identify the dominant factors that affected the birds’ community in the Johor Bahru region.

Résumé :

The bird nest adoption program in Jatimulyo is one of the activities to protect birds from extinction. This activity is carried out by keeping birds that are breeding in nests in community forest habitats. The development of this concept was expected to protect the birds and increase the economic value of the community-owned forest from the non-timber sector that supported environmental sustainability. However, the program is not yet implemented in the whole area of Jatimulyo Village. This study aimed to determine the strategy for developing the bird nest adoption program in Jatimulyo Village.

Abstract Inter-annual variations in the total number of birds in floodplains of rivers are mainly associated with their flooding. The minimum population density during the nesting period was in a year with high and prolonged spring floods. The restoration and maximum development of shrubs took place with a significant simultaneous increase in the abundance of birds in subsequent years. Drying and simplification of vegetation cover were noted in all floodplain bird habitats during low-water periods. This process was accompanied by a decline in the number of birds.

After a long period of decline, the number of forest birds has increased in Sweden in recent decades. Whether this trend is due to an increase in forested area, forest quality, climate change, or a combination of these factors, remains unclear. Here, we compared forest bird data from a local winter point count route around Storuman in Swedish Lapland between 1986 and 2017, with the development of regional forest composition and local weather conditions. We suggest that rather than changes in average annual, winter, or summer local temperatures or precipitation, the main drivers behind increasi

Caucasian hogweeds, mainly the Sosnowsky’s hogweed Heracleum sosnowskyi and the giant hogweed Heracleum mantegazzianum, create one of the most problematic plant invasions in the world. Due to their large size (weeds reaching 4–5 meters in height), they seem to be herbaceous plants that can threaten birds living in forest stands. This research quantified the structure and diversity of the forest birds’ community in forests with varying areas of invasive hogweeds located in south-eastern Poland. Changes in the accompanying non-forest birds’ community were also assessed. The study addressed the f

The vaccinę virus replicates well in CEF giving a titer of up to107.5 TCID50 per ml. In spite of its pathogenicity for CEF, the vaccine has no pathogenicity for chickens as shown by the absence of gross and histopathological lesions in the bursa of Fabricius (BF) of birds infe
