The global occurrence of green spaces has observed continuous decline over the last decades and at the same time, agriculture-based regions are increasingly scrambling to find alternative sources of revenue. The study utilized the satellite images of Landsat and Sentinel sensors in different intervals in order to show how remote sensing, geographic...

Az antimikrobiális rezisztencia (AMR) globális egészségügyi probléma, amelynek széleskörű tanulmányozása aktuális feladat. Tanulmányukban a szerzők áttekintették az AMR vadon élő madarakban való jelenlétével kapcsolatos jelenlegi szakirodalmat. A legtöbb tanulmány az elmúlt évtizedben jelent meg (312 cikk 76,9%-a) és a WHO által prioritásként kezel...

Hooded Crow (Corvus cornix), originally native to agricultural areas, has become widespread in urban areas in recent decades. However, this process has negative consequences on urban animals and humans. Due to these problems, the control of urban crow populations is needed. Crows also cause significant damage to wildlife management, and are constan...

Introduction: Urbanization has led to a recent surge of interest in urban biodiversity, and wildlife responses to urban environments have become a hot topic in environmental sciences and biodiversity conservation. However, adaptations to urbanization and the factors driving them are less understood. Methodology: We studied possible morphological...

Study the breeding biology of Hooded crow using drone

Vancomycin resistant enterococci (VRE) are high priority nosocomial bacteria with a potential for zoonotic transmission. Thus, its emergence outside health establishments is a major concern. In order to study the prevalence of VRE in wildlife, we collected 221 faecal samples from free-ranging Hooded Crow (Corvus cornix) from urban and rural habitat...

In recent years, the Hooded crow (Corvus cornix) has become one of the most successful wild bird species in urban environments across Europe. Hooded crows can cause several problems in cities, including trash scattering, noise disturbance, and aggressive behavior toward humans or pets, and they can be potential vectors of pathogens. To find effecti...

During winter, a large number of rooks gather and defecate at the park of a university clinic. We investigated the prevalence of extended-spectrum beta-lactamase (ESBL)–producing Escherichia coli in these birds and compared recovered isolates with contemporary human isolates. In 2016, fecal samples were collected from 112 trap-captured rooks and in...

Urbanization is one of the most prevalent drivers of biodiversity loss, yet few taxonomic groups are remarkably successful at adapting to urban environments. We systematically surveyed the global literature on the effects of urbanization on species of family Corvidae (crows, choughs, jackdaws, jays, magpies, nutcrackers, ravens, rooks, treepies) to...

The Woodpigeon (Columba palumbus) is a species typically known for its successful colonization of urban habitats across Europe in the last century. However, this is a comparably new phenomenon for Belarus because active colonization of towns and cities by the urban Woodpigeon only started within this country in the late 2000s. The spread of the urb...

Abstract Crows have successfully colonized many cities, and urban zoos have been important in this process. To evaluate why zoos attract crows, we quantified crow numbers and behavior in three zoos in Europe (Debrecen, Edinburgh, Vienna) and one in Asia (Sapporo). Data were collected in 445 surveys over 297 days in summer 2014 and winter 2014–2015....

Corvids, mainly Hooded Crows (Corvus cornix L.) and Rooks (Corvus frugilegus L.) have colonised and spread in many European cities in recent decades. They are often considered as pests due to their noise, littering, aggression to humans and pets, and predation on birds of urban environments. Consequently, the control and/or management of corvids ma...

A Debreceni Egyetem Mezőgazdaság-, Élelmiszertudományi és Környezetgazdálkodási Kar Természetvédelmi Állattani és Vadgazdálkodási Tanszéke 2006 óta foglalkozik városi környezetben előforduló varjúfélékkel, kiemelt figyelmet fordítva a dolmányos varjúra (Corvus cornix L. 1758), amely jelentős állománynövekedése számos problémát okoz mind a városi ma...

Urbanization is an important ecological factor that modifies the living conditions of species at multiple levels. Urbanization is also influenced by human-animal relationships. We studied the effects of human-related factors on nest site selection of the Eurasian Magpie (Pica pica) by using both historical and contemporary data on the nest sites of...

In 2014, 7.2 % of Germany’s territory was used for the cultivation of maize. Several studies have shown that maize fields are of minor importance for breeding bird species. The value of maize fields as a habitat for birds has rarely been investigated during summer and autumn. Mist-net data were obtained using 15 nets in a maize field near Gießen, G...

The common raven (Corvus corax) is an abundant generalist of the northern hemisphere, known to congregate and roost near human-related food sources. Due to a growing human-footprint and associated anthropogenic food subsidies, raven populations have increased dramatically over the past several years throughout the USA. The sub-arctic region has als...

In the past decade Hooded Crows showed a significant growth in Debrecen. The aim of this study was to become acquainted with Hooded Crows nest-site selection in urban circumstances. The research revealed that Hooded Crows are not choosy when it comes to selecting the species of the trees, but we noticed differences regarding nesting height - Hooded...

The Hooded Crow (CorvuscornixL.) have moved in several Hungarian cities in the last few decades. It is breeding in Debrecen since 1959, and nowdays it’s presence can be detected at all points of the city, it is an permanent breeding species of the bird fauna. Our knowledge about the nature of urban races, including motion patterns, area fidelity is...

In the past decade, the population of the Hooded Crow has shown significant growth in Debrecen, Hungary. The aim of this study was to become acquainted with the nest-site selection behavior of Hooded Crows in urban spaces. While our research revealed that the Hooded Crow is not particular when it comes to selecting among tree species for nesting, w...
