Abstract

Studies on the feeding biology of Lesser Kestrel (Falco naumanni) have limited in Turkey. The aim of this study was to contribute to the knowledge of its feeding ecology in arid areas. In this study, pellet compositions of Lesser Kestrel were examined. Compositions of 17 pellets of Falco naumanni were used in the study. 182 preys which belong to 8 different taxa were found in the diet composition. Insecta (f= 59.34%) and Arachnida (f= 37.36%) taxa were the main preys in the diet composition of Falco naumanni. Solpugidae (Arachnida) (f= 35.16%) had the high prey rate in the dietary composition. The significant ratio of members of Solpugidae was similar to the results of the other semi-arid and arid areas.

Aralık, Iğdır (Doğu Anadolu Türkiye)'da küçük kerkenez (Falco naumanni Fleischer) diyeti hakkında ön veri

Abstract

Türkiye'de Küçük Kerkenez’in (Falco naumanni) beslenme biyolojisi ile ilgili sınırlı sayıda çalışma vardır. Bu çalışmanın amacı, bu türün kurak alanlardaki beslenme ekolojisine yönelik bilimsel değerlendirmelere katkıda bulunmaktır. Bu çalışmada Küçük kerkenezin pelet içerikleri incelenmiştir. Çalışmada türe ait 17 peletin içeriği değerlendirilmiştir. Diyet bileşiminde 8 farklı taksona ait 182 av tespit edilmiştir. Falco naumanni'nin diyet bileşimindeki ana avlar; Insecta (f= %59,34) ve Arachnida (f= 37,36%) taksonlarıdır. Arachnida’dan Solpugidae familyası (f= %35,16), diyet bileşiminde yüksek av oranına sahiptir. Solpugidae üyelerinin bu belirgin oranı, diğer yarı kurak ve kurak alanların sonuçları ile benzerlik göstermektedir.
