The general objective of this work was to analyze changes in bird species richness, diversity, and composition in parks located in the urban a...

Since the 19th century, the flamingo has been a regular visitor to wetlands in Bulgaria. In the last decade, the species has been a year-round resident of Lake Atanasovo near the city of Burgas on the Black Sea coast. In 2023, the birds in the lake began to nest for the first time, but did not lay eggs. On 16 June 2024, three 5-7-day-old flamingos...

Communal roosts are essential stopover sites for migratory birds. Monitoring the diurnal activity patterns of birds in communal roosts (DAPBCR) is crucial for understanding their migratory behavior and ecological needs. This information is crucial for guiding habitat conservation and management strategies and assessing the impact of environmental c...

Mixed-species flocks (MSF) represent an important form of social organisation in bird communities worldwide. Despite its likely importance in flock formation and cohesion, the role of vocal communication in the formation and maintenance of MSF in birds is hitherto understudied. In this study, we examine if a species' centrality within a mixed-speci...

The Pallid Harrier Circus macrourus is a long-distance migratory species whose westward expansion into Europe began in the early 21st century. Although historically rare in Croatia, an increase in observations since 2016 has led to its recognition as an irregular species, particularly during spring and autumn migration. Most recorded sightings are...

The Common Tern Sterna hirundo nests colonially in both marine and freshwater habitats with incubation and chick rearing being shared parental responsibilities.

Seed dispersal of plants affects the spatial structure and population dynamics, contributing to ecosystem functioning. Birds are among the most important seed dispersers. Preferences of birds in fruit and berry consumption are potentially significant selective pressures on the evolution of fruit traits that affect plant fitness. European ivy (Heder...

Introduction: The "win-stay, lose-switch" (WSLS) strategy used by birds involves decisions to maintain or alter the characteristics of the subsequent nest according to the outcome of the previous one. In salt marshes, nest failure occurs due to flooding, predation, or tipping, creating a trade-off for nest placement: it should be low enough to avoi...

Before rice became widely known in its current form, sago was the staple food of Indonesian people. Sago is eaten in the form of papeda, a type of porridge, or other preparations. Sago is unique as a source of carbohydrates because it is produced in wetlands, a natural habitat for straw. This condition has benefits for the environment but is less e...

The distribution–abundance relationship (DAR) is a well‐established macroecological pattern, where more locally abundant species are also more widespread across landscapes. However, it is not clear whether this relationship is temporally invariant, or how destabilization may manifest. Here, we examine the DAR at the landscape level in a unique but...

The spatial configuration and management of agricultural and other land-use practices can affect ecological assemblages, but how resident and migratory species respond to land uses is not well known, hindering our understanding of the effects of land use on biodiversity. Here, we compare alpha and beta diversity and ecosystem functioning for reside...

Birds are among the most charismatic animals on our planet. Worldwide, there are about 11,000 different avian species. BirdLife International (2024) has listed 1,211 bird species that occur in India, demonstrating its immense diversity. Of these species, the majority (about 80%) are restricted to the Himalayas. To contribute to our knowledge on avi...

The migration and wintering of the Mistle Thrush (Turdus viscivorus) is the least known of the other common nesting thrushes in Europe. It is also an understudied species in Hungary, detailed studies having been carried out nearly 50 years ago. The aim of the present study was to summarise the data on migration and wintering of this species that ha...

Occupancy prediction has garnered increasing attention in recent years for its comprehensive fine-grained environmental representation and strong generalization to open-set objects. However, cumbersome voxel features and 3D convolution operations inevitably introduce large overheads in both memory and computation, obstructing the deployment of occu...

Urban habitats are rapidly changing, making the conservation and management of species adapted to these environments challenging.

Avian pathogenic Escherichia coli (APEC) causes colibacillosis in poultry; this type of bacteria is an extraintestinal pathogen E. coli. Unlike other E. coli pathogen groups, the characteristics of APECs cannot be identified by a single group. Serotyping and biotyping are frequently performed for isolates found in colibacillosis infections. The est...

In the mid-fourteenth century, the Jochid ulus went through a phase of extreme political turbulence. Following the death of the last Batuid khan Berdibek (r. 1357–1359), during the next two decades, circa 1360–1380, a high number of power contenders rose at both the central and the local levels of the ulus .
