Abstract:
... We present the first report of Greater Flamingo Phoenicopterus roseus in Brazil, an individual at Araruama, Rio de Janeiro state, in late November 2021 until at least early April 2022, and discuss hypotheses to explain its appearance so far from the species' normal distribution. We believe that it was either an escapee from a captivity or a genuine vagrant that reached Brazil due to bad weather. W ...

Abstract:
... Campylobacter hepaticus causes Spotty Liver Disease (SLD) in layer hens, resulting in mortality and productivity losses. Like other Campylobacter species, C. hepaticus is a fastidious organism that requires microaerobic conditions to grow and efficiently replicate. Despite its apparent vulnerability to environmental conditions, it is suspected that there are environmental sources of C. hepaticus t ...

Abstract:
... A total of 26 Gram-negative, motile, gently curved, and rod-shaped isolates were recovered, during a study to determine the faeco-prevalence of Helicobacter spp. in urban wild birds. Pairwise comparisons of the 16S rRNA gene sequences indicated that these isolates belonged to the genus Helicobacter and phylogenetic analysis based on the 16S rRNA gene sequences showed that the isolates were separat ...

Abstract:
... Highly pathogenic avian influenza (HPAI, Gs/Gd lineage) was introduced to Europe in 2005 and has since caused numerous outbreaks in birds. The 2020–2021 season was the hitherto most devastating when considering bird numbers and duration in Europe. Surveillance data, virologic results and epidemiologic investigations from the 2020–2021 outbreaks in Sweden were analysed. Subtypes H5N8 and H5N5 were ...

Abstract:
... Inhibitory control is one of several cognitive mechanisms required for self-regulation, decision making and attention towards tasks. Inhibitory control is expected to influence behavioural plasticity in animals, for example in the context of foraging, social interaction or responses to sudden changes in the environment. One widely used inhibitory control assay is the ‘detour task’ where subjects m ...

Abstract:
... Wild and feral birds are known to be involved in the maintenance and dissemination of clinically-important antimicrobial-resistant pathogens, such as extended-spectrum β-lactamase (ESBL) and carbapenemase-producing Enterobacteriaceae. The aim of our study was to evaluate the presence of ESBL- and carbapenemase-producing Escherichia coli among wild and feral birds from Greece and to describe their ...
... Trichomonas gallinae is the causative protozoan parasite of avian trichomonosis, an infectious disease of wild bird species. Since an outbreak in the UK in 2005, avian trichomonosis has resulted in mass mortality events in greenfinch (Chloris chloris) and chaffinch (Fringillia coelebs) populations. Given its proximity to the UK, it is important to monitor the emergence of T. gallinae in Ireland. T ...

Abstract:
... Avian influenza (AI) is a contagious disease of birds with zoonotic potential. AI virus (AIV) can infect most bird species, but clinical signs and mortality vary. Assessing the distribution and factors affecting AI presence can direct targeted surveillance to areas at risk of disease outbreaks, or help identify disease hotspots or areas with inadequate surveillance. Using virus surveillance data f ...

Abstract:
... Parasites have developed many strategies to ensure their development, multiplication, and dissemination, including the use of reservoir hosts that are often nondomesticated species. Despite drastic reductions in their populations, wild birds remain widespread worldwide and could constitute some of these reservoirs. We focused on the identification of wild bird species harboring parasite stages in ...
... We determine the exposure of wild birds to pesticides via consumption of fludioxonil-treated winter wheat seeds following autumn drilling. We recorded the density of seeds left on the soil surface, bird density, and consumption of pesticide-treated seed by birds using camera traps. We calculated the dose ingested by each bird species in a single feeding bout and if they ate treated seeds exclusive ...
... Avian orthoavulavirus 13 (AOAV-13), formerly known as Avian paramyxovirus 13 (APMV-13), is found scatteredly in wild birds around the world. Although four complete genome sequences of AOAV-13 had been identified since the first discovery in Japan in 2003, the information available on the genetic variation and biological characteristics of AOAV-13 is still limited. In the present study, we isolated ...

Abstract:
... Highly pathogenic avian influenza (HPAI) outbreaks have become increasingly frequent in wild bird populations and have caused mass mortality in many wild bird species. The 2020/2021 epizootic was the largest and most deadly ever reported in Europe, and many new bird species tested positive for HPAI virus for the first time. This study investigated the tropism of HPAI virus in wild birds. We tested ...

Abstract:
... West Nile Virus (WNV) is maintained in nature in a bird-mosquito cycle and human infections follow a seasonal pattern, favored by climatic conditions. Peloponnese Region, located in Southern Greece, initiated an active WNV surveillance program to protect public health during 2019–2020. The project included monitoring of avian hosts and mosquito vectors, while sampling locations were prioritized af ...

Abstract:
... Since the emergence of the Goose/Guangdong H5 lineage in 1996 and spillover of highly pathogenic avian influenza (HPAI) from poultry to wild birds, outbreaks have become increasingly frequent in wild birds. The latest outbreak in the Netherlands occurred in the fall-winter of 2020–2021 and was linked to incursions of HPAI H5N8 virus. During the larger national outbreak, wild birds in rehabilitatio ...
... Mycoplasma spp. are important pathogens in poultry and cause high economic losses for poultry industry worldwide. In other bird species (e.g. white storks, birds of prey, and several waterfowl species), Mycoplasma spp. are regularly found in healthy individuals, hence, considered apathogenic or part of the microbiota of the upper respiratory tract. However, as Mycoplasma spp. are absent in healthy ...

Abstract:
... Raptors are some of the most at-risk groups of birds in the world and saving these top predators is essential for maintaining the health of many ecosystems. After hospitalization, raptors are often released when muscular recovery is still unfitting when they are unable to hunt efficiently and are at risk of dying from starvation within a few days. On the other hand, if a convalescent bird is train ...
... The Sardinian partridge is a monogamous wild bird species of least concern according to IUCN list at present, though formerly accounted among threatened species for decades. The creation of couples is crucial in captivity, because forced pairing in cages can lead to poor welfare of birds, specially of females. This study investigated the impact of single versus couple caging of Sardinian partridge ...

Abstract:
... Worldwide, wild birds are frequently suspected to be involved in the occurrence of outbreaks of different diseases in captive‐bred birds although proofs are lacking and most of the dedicated studies are insufficiently conclusive to confirm or characterize the roles of wild birds in such outbreaks. The aim of this study was to assess and compare, for the most abundant peridomestic wild birds, the d ...
... Moellerella wisconsensis is an Enterobacteriaceae with unclarified dispersion and pathogenicity. During an ongoing investigation about antimicrobial resistance in Greece, the occurrence of M. wisconsensis was evaluated among wild birds and humans. A total of 445 wild bird and 2000 human fecal samples were collected and screened for the presence of the organism. Subsequently, all M. wisconsensis st ...

... Recent foodborne illness outbreaks have heightened pressures on growers to deter wildlife from farms, jeopardizing conservation efforts. However, it remains unclear which species, particularly birds, pose the greatest risk to food safety. Using >11,000 pathogen tests and 1565 bird surveys covering 139 bird species from across the western United States, we examined the importance of 11 traits in me ...
