Abstract:

 The aim of this study is to investigate the breeding biology of Collared pratincole, a migratory bird species in AntalyaBoğazkent Turkey. There are a lot of habitat types in research area of 200 ha. This speciality serves great biodiversity. Field work was carried out from March to October between 2016 and 2017. 35 individuals and 16 nests were found in the first year and 25 individuals and eight nests in the next year. The egg volume has been calculated according to the formulation V0.51 X L X W2 while egg index has been figured with regard to EI100xWL formulation. According to the hatchling size, the breeding success of the species was 86.7 in 2016 and 85.7 in 2017.Considering the fledgling size, the figures were 46.4 in 2016 and 66.7 in 2017 respectively. Many factors affecting the breeding success of the species were specified in the region. Hooded crows Corvus cornix, for example, was detected as being the natural predator of the species. Furthermore, the invasion of the breeding areas by humans and human-related activities such as construction, tourism and agriculture also harmfully affects the breeding success. According to our study AntalyaBoğazkent is a very important bird area in Turkey.

 Bu çalışmanın amacı AntalyaBoğazkentte göçmen bir kuş türü olan Bataklık Kırlangıcı Glareola pratincolanın üreme biyolojisinin incelenmesidir. Yaklaşık 200 hektarlık araştırma alanında, pek çok farklı habitat tipi vardır. Bu özelliği geniş bir biyoçeşitlilik sunmaktadır. Arazi çalışmaları 2016-2017 yıllarında Marttan Ekime kadar gerçekleştirilmiştir. İlk yıl alanda 35 birey ve 16 yuva, sonraki yıl ise 25 birey ve 8 yuva bulunmuştur. Yumurta hacmi V0.51 X L X W2 formülüne göre, yumurta indeksi EI100xWL formülüne göre hesaplanmıştır. Türün üreme başarısı, açılan yumurta sayısına göre, 2016 yılında 86.7 ve 2017 yılında 85.7, juvenil yavru sayısına göre 2016da  46.4, 2017de  66.7dir. Bölgede türün üreme başarısını etkileyen pek çok faktör tespit edilmiştir. Örneğin, Leş kargası Corvus cornix, türün doğal predatörü olarak belirlenmiştir. Aynı zamanda üreme alanlarının insanlar tarafından işgal edilmesi, yapılaşma, turizm ve tarımsal aktiviteler de üreme başarısını olumsuz yönde etkilemektedir. Çalışmamıza göre AntalyaBoğazkent, Türkiyedeki çok önemli bir kuş alanıdır.
