We recorded bird species by using point counts and fixed-route monitoring. At Rajdhani Jalashay, a total of 73 species were recorded, of which 15 species were winter visitors. Two species were in the Near-threatened category: Ferruginous Duck (Aythya nyroca) and Alexandrine Parakeet (Psittacula eupatria), while the others were of least concern. At Mustafapur wetland, 67 species were recorded with 11 species as winter visitors. Simpson’s species diversity index was 0.78 at Rajdhani Jalashay, and 0.81 at Mustafapur wetland. The number of species of waders was 17 at Mustafapur wetland and 11 at Rajdhani Jalashay. The total number of Lesser Whistling-duck (Dendrocygna javanica), a resident bird was almost double (526) at Mustafapur wetland than that at Rajdhani Jalashay (234). The nitrate level was twice higher and the phosphate level was four times higher at Mustafapur wetland than those at Rajdhani Jalashay. The difference in species number and composition between the two wetlands may be attributed to the eutrophication resulting from high nitrate and phosphate levels at Mustafapur wetland. Unfortunately, the Mustafapur wetland is under threat due to human influences. The protection and sustainable management of natural wetlands is required for saving the biodiversity of the area.","PeriodicalId":35966,"journal":{"name":"Ornis Hungarica","volume":" 3","pages":"13 - 28"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138618547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, they have not been studied in Nepal, although there are increasing sightings of these deformities. Injuries, genetic mutations, environmental factors, infections, radiation, and other factors can cause deformities. In our study, we collected data from numerous field trips, conversations with bird watchers and experts, and social media posts in Nepal. We reported 24 cases of avian deformities in 16 different bird species across 12 districts in Nepal, suggesting that certain abnormalities persist in a high proportion of previously unstudied birds. We discovered different types of color abnormalities (6 cases of leucism, 3 albinism, 4 partial leucism, 1 brown mutation, 1 melanism, and 3 unidentified color aberration), 5 cases of avian keratin disorder (AKD), and 1 case of both leucism and AKD. The majority of these cases affected corvids and other birds frequently living and nesting near human settlements, indicating that causative agents such as anthropogenic toxicants and environmental degradation could be important contributors. There is a scarcity of research on avian deformities and diseases in Nepal, thus more research on avian abnormalities, such as the pathophysiology of AKD and genetic studies, should be performed.","PeriodicalId":35966,"journal":{"name":"Ornis Hungarica","volume":" 7","pages":"151 - 164"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138615089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CES program tracks breeding bird populations with standard methods. The studied species breeding in Hungary were from genera Sylvia, Curruca, and Phylloscopus. Among these species, the trends of some forest birds, like Eurasian Blackcap (Sylvia atricapilla), Lesser Whitethroat (Curruca curruca), Common Chiffchaff (Phylloscopus collybita) and Willow Warbler (Ph. trochilus) showed no substantial changes, and one of the open-habitat species, the Barred Warbler (Curruca nisoria) – a long distant migrant – showed decreasing trends. The Garden Warbler (Sylvia borin) – a trans-Saharan migrant but forest dweller – also experienced population declines. Short-distance migrants maintained stable populations. Common Whitethroat productivity displayed an increasing trend to compensate for population decline. Upon examining the Eurasian Blackcap, this study detected a strong relationship between the number of adult birds, productivity, and the number of adults captured the following year.","PeriodicalId":35966,"journal":{"name":"Ornis Hungarica","volume":" 1","pages":"74 - 88"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138615423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conservation actions regarding Falco vespertinus led to a great increase in its presence in the area. This rise was believed to coincide with an increase in the prevalence of hematophagous ectoparasites breeding in the nests, with a potential negative impact on the attractiveness of the breeding site. Ectoparasites collected from the nestlings’ bodies almost entirely belonged to a single species, Diptera Carnus hemapterus, with a quite variable prevalence in different years. Maximum ectoparasite load was consistently linked to younger than two weeks old chicks. Carnus hemapterus may pose a threat to less resilient specimens of Falco vespertinus because it feeds on live tissues, increases metabolic expenditure, and can introduce blood parasites. Nonetheless, this species is part of the ecosystem shared with the falcon and might have a conservational value itself. We propose that higher occurrence of this ectoparasite might be linked to diet parameters, especially the availability of small mammals and the lingering of prey remnants in the nests, as well as to the age of the parasitized nestlings. These findings might have important implications for the conservation of this rare Falco species.","PeriodicalId":35966,"journal":{"name":"Ornis Hungarica","volume":" 8","pages":"138 - 150"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138619883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Linear infrastructure development, such as roads, railways, pipelines, canals, and power lines, is expanding rapidly, causing the degradation and fragmentation of habitats, and leading to the loss of biodiversity. Unfortunately, the impacts of linear infrastructure on bird populations in India have not been adequately studied, resulting in limited understanding and few measures to mitigate these impacts.

The howl of a Gray Wolf was recorded in the frequency range from 300 to 1,100 Hz. Red Fox barking was recorded in the frequency range from 750 to 1,000 Hz. Barking of domestic dogs was recorded in the frequency range from 250 to 1,500 Hz. The vocalization of the Eurasian Eagle-Owl had an independent character inherent in the biology of the species. The Eurasian Eagle-Owl, with its cries, involuntarily provoked the entry of canines into joint vocal interaction, which can be explained by the high social activity of the latter. Co-vocalizations of the Eurasian Eagle-Owl and canines were noted in winter, spring and autumn, but mainly in spring (50%). The increased use of autonomous voice recorders, which record spontaneous vocalizations emitted by animals over long periods, will allow us to better document and study the importance of such interspecific interactions.","PeriodicalId":35966,"journal":{"name":"Ornis Hungarica","volume":" 94","pages":"61 - 73"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138613555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The landscape structure of their hunting range, therefore, affects the composition of their prey, knowledge of which can be a good starting point for estimating the size of their hunting range. Our goal was to estimate whether owls catch most of their prey within a circle with radius of 1, 2, 3, 4 or even 5 kilometres. In this study, we used five pellet samples of different size, collected between 2015 and 2019 from a settlement near the Drava River (Péterhida, Hungary). Our results showed that the annual distribution, diversity, and evenness of small mammal species detected from the samples was similar regardless of the sample size. The distribution of small mammal functional groups preferring urban, open, forest and wetland habitats was also similar. For this reason, the pellet samples were merged. Our results suggest that Western Barn Owls catch a significant part of their prey within a circle of 2-kilometre radius around its breeding or roosting site in the landscape, which consists of patches of habitat with a mosaic distribution. In a hunting range of this size, the proportion of small mammal functional groups preferring different habitats obtained from the pellets overlapped with the proportion of their preferred habitats.","PeriodicalId":35966,"journal":{"name":"Ornis Hungarica","volume":"227 2","pages":"192 - 202"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138621269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on these data, it can be observed that the crane was never a frequent nesting species in Hungary. It probably nested regularly until the early 19th century, then occasionally until the 1910s, after which, apart from two occasional reports, no nesting data were available until 2015. From this year onwards, it started nesting again in the Transdanubian region. In the examined period, 55.6% of the nests (n=25) originated from the Transdanubian region, 37.0% from the Tiszántúl region, and 7.4% from the Duna-Tisza area. The observations recorded during the nesting period showed a strong correlation with the spatial distribution of confirmed nests. 82.6% of the observations recorded (n=23) were from the Transdanubian region, 13.0% from the Tiszántúl region, and 4.3% from the Duna-Tisza region. The distribution of nesting data between regions varies not only spatially but also temporally. The nesting data from the Duna-Tisza area and Tiszántúl region date back to the 19th century, with the exception of one report, while the most recent nesting data are from the Transdanubian region (Vas and Veszprém counties).","PeriodicalId":35966,"journal":{"name":"Ornis Hungarica","volume":"45 10","pages":"99 - 109"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138626561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
