Öğe Breeding Biology of the Yellow-legged Gull (Larus michahellis, Naumann, 1840): a Small Island Population in Southwestern Türkiye(ABADER (Adıyaman Bilimsel Arastırmalar Dernegi), 2022) Karaardiç, Hakan; Köse, Feyyaz; Ozturk, YaseminUrbanization and fisheries affected a rapid increase in seagull populations in western Mediterranean populations of the yellow-legged gull. The main reason is the increased food resources such as fisheries, big ports, and dumps. In this study, we aimed to understand and to compare the breeding biology of the yellow-legged gull in eastern Mediterranean. We studied on the small island in southwestern Türkiye between 2013 and 2015. All nesting sites were determined, marked, and monitored once a week. The breeding season has started in late February, nesting and laying eggs have started at the beginning of March, and they left the island in the second half of June after fledging. The incubation period is 29.17±2.85 days, only one clutch in a season and 2 or 3 eggs were laid in the nests. There was a slight increase in the number of pairs and nests between years but there is no significant difference in all parameters such as laying date, clutch size, hatching and fledging success in Pırasalı Island population and the rate of both hatching and fledging success are lower than western Mediterranean populations. While predation is the weakest factor for lower breeding success, intraspecific predation may be the factor but the main effect is the lower food abundance for the hatchlings. © 2022, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).

This contour canal system and marsh areas encompass water and land habitats that attract a diverse bird species. After nine years of observations, we identified a total of 234 species of avifauna belonging to 21 orders and 53 families. Passeriformes had the most diversity with 94 species, followed by Charadriiformes (49 species), Anseriformes (17 species), Accipitriformes (15 species), Pelecaniformes (12 species), and the remaining 16 orders had the least diversity. A total of 65 species were identified as residents, 71 as summer visitors, 43 as winters visitors, and 55 as passage migrants. Researchers determined that 55 species of marsh fauna breed in the area. Furthermore, 23 species were found to be probable breeders in the marsh, while 10 species were likely to breed, and the remaining 146 species were not breeding. There are 217 species categorized as Least Concern (LC), nine species categorized as Near Threatened (NT), four species categorized as Vulnerable (VU), and two species categorized as Endangered (EN). This study provides basic information on the avifauna diversity and status of Hürmetçi Marsh for future management and conservation strategies and offers solutions for the sustainable use and conservation of the area. © 2024 Iranian Society of Ichthyology.Öğe FEATHER MITES (ACARIFORMES: ASTIGMATA) FROM THE BIRDS RINGED AT THE KARPAZ BIRD RINGING STATION (İSKELE, NORTH CYPRUS)(University of Tyumen, 2025) Eren, Gökhan; Kızılkaya, Esat; Karaardiç, Hakan; Bukan, Mustafa Güray; Karaca, MehmetFeather mites (Astigmata: Analgoidea and Pterolichoidea) examined in this study were collected from live birds captured and ringed in the autumn of 2024 at the Karpaz Bird Ringing Station. A total of 17 feather mite species from the families Proctophyllodidae (Dolichodectes—1, Joubertophyllodes—1, Monojoubertia—1, Proctophyllodes—10 species) and Trouessartiidae (Trouessartia—4 species) have been detected during the study. All of these are new records for the fauna of Cyprus. Males and females of all recorded species are illustrated in the provided photos. © Acarina 2025.Öğe First Ringing Station in Cyprus, Karpaz Bird Ringing Station: Results of Autumn Migration Season in 2024(Adiyaman University, 2025) Karaardiç, Hakan; Kızılkaya, Esat; Bukan, Mustafa GürayCyprus is one of the important islands in the Western Palearctic for bird migration routes, especially on the eastern Mediterranean route. In contrast to Western Europe, research on bird migrations in Eastern Europe and the Eastern Mediterranean remains limited. Due to its geographical location and surface area, Cyprus hosts millions of migratory birds in the Eastern Mediterranean region during the Eastern European bird migrations. The Karpaz Bird Ringing Station, established in Northern Cyprus, has the potential to fill many gaps. Regular ringing activities started in the autumn season of 2024 at the station, a total of 157 meters of mist nets were used, and 1,436 birds from 39 species were ringed. The most frequently ringed species were the Eurasian blackcap, common chiffchaff, European robin, Sardinian warbler, willow warbler, song thrush, stonechat, Spanish sparrow, black redstart, and common redstart. According to the results, the long-distance migrants, such as willow warblers, common redstarts, and blackcap individuals, have higher fat scores. These preliminary data reveal the importance of the role of Cyprus in bird migrations. Although there is only one control bird (Hungarian control), increasing the recapture data (especially between Israel, Türkiye and Cyprus) will significantly contribute to the determination of migration dynamics (migration phenology, stopover ecology, migration routes, individual physiological changes and more) in the Eastern Mediterranean part of bird migrations under the western Palearctic migration route. © 2025, Adiyaman University.

But, there is scarce information about their distribution in these regions. In this work, Peregrine falcon (Falco peregrinus), Eleonora’s falcon (Falco eleonorae), Merlin (Falco columbarius) and Eurasian Hobby (Falco subbuteo) were identified in the studied area. The study was conducted around Adrasan bay on the coast line of southern Turkey from April to October during 2013-2018. The Eleonora’s falcon and the Peregrine falcon have successfully bred in this region, regularly. A large breeding colony of the Alpine swift (Apus melba) is located close to cliffs in the study area. Both falcon species had many successful attacks on Alpine swifts in the sea. This food abundance may be effective with the safety nesting areas for both Peregrine falcon and Eleonora’s falcon. © 2020, Adiyaman University. All rights reserved.
