Abstract

Abstract

 In Belgrad Forest near Istanbul-Turkey we surveyed the Tawny Owl’s distribution, population density and habitat preferences. The study area was divided into 18 sample areas, which are 2x2 km. We located a total of 93 tawny owls (Strix aluco L. 1758): 34 pairs, 14 single males, 6 single females and 5 juveniles. Tawny Owls preferred deciduous old forest stands near streams and dams in Belgrad Forest. Also, their diet consisted mainly of Rodentia (93%) and a small percentage of birds, amphibian and insects (7%).

 Keywords: Tawny owl, Strix aluco, Belgrad Forest, population, Istanbul, vocalization.

Kısa Özet

 Bu çalışma Belgrad Ormanı’nda yaşayan Alaca Baykuş (Strix aluco L. 1758)’ların yayılış alanları, habitat tercihleri ve populasyon yoğunluğunun tespit edilmesi amacıyla yapılmıştır. Çalışma alanında 2x2 km’lik 18 örnek alan belirlenmiştir. Belgrad Ormanı’nda 34 çift olmak üzere, 14 yalnız erkek, 6 yalnız dişi ve 5 genç birey toplam olarak 93 alaca baykuşun yaşadığı tespit edilmiştir. Alaca baykuşların, Belgrat ormanındaki gölet ve dere kenarlarındaki yaşlı meşcerelerde etrafında yoğunlaştıkları saptanmıştır. Ayrıca besinlerinin büyük çoğunluğunu (%93) kemirgenler (Rodentia), küçük bir kısmını ise kuşlar, kurbağalar ve böcekler (%7) teşkil etmektedir.
