Habitat and Nest Site Selection of the European Rollers in the Northern Anatolia
Gökkuzgunların Kuzey Anadolu’daki Habitat ve Yuva Yeri Seçimi

Necmiye ŞAHİN ARSLAN [1] , Gönül ARSLAN AKVERAN [2]


In this study, habitat preferences of the European Rollers (Coracias garrulus) in the Northern Anatolia was investigated, in 2014 breeding season. Total of 31 breeding pairs in 4 certain roller sites were located. The average distance between the breeding territories was 1.2 km in one of the roller sites with 17 pairs. Both solitary and colonial breeding pairs were recorded. Overall,  8, 2 and 2 nests (total of 12 nests) were located on sand quarries, concrete buildings and abandoned magpie nests on electrical poles, respectively. The habitat preferences were determined within a radius of 300 m and 1000 m around the nest site for the breeding and foraging habitats, respectively. We conducted the spatial analysis in ArcGIS 10.5 using Corine Land Cover 2012 database. Agricultural areas were the major land cover types where the European Rollers breed in our study. Use of unfavorable habitats and other nest sites including magpie nests necessitated a conservation program for the European Rollers in the study area.

Bu çalışmada, gökkuzgunların 2014 yılı üreme döneminde Kuzey Anadolu’daki habitat tercihleri değerlendirilmiştir. 4 ayrı üreme bölgesinde toplam 31 adet çift tespit edilmiştir. 17 çiftin bulunduğu üreme alanında yuvalar arasındaki ortalama mesafenin 1.2 km olduğu belirlenmiştir. Çalışma alanı içinde hem soliter çiftler hem de koloniyal halde üreyen çiftler kaydedilmiştir. 8 tanesi toprak yarlarda, 2 tanesi beton binalardaki oyuklarda, 2 tanesi de elektrik direklerinde bulunan saksağan yuvalarında olmak üzere toplam 12 adet aktif yuva yeri tespit edilmiştir. Gökkuzgunların üreme ve beslenme habitatı tercihleri sırasıyla 300 ve 1000 m yarıçaplı alanlarda değerlendirilmiş ve alansal analizler ArcGIS 10.5 programında Corine Land Cover 2012 veri tabanı kullanılarak gerçekleştirilmiştir. Tarım arazilerinin, çalışma alanı içindeki gökkuzgunların ürediği alanlarda en önemli arazi örtüsü tiplerini oluşturduğu belirlenmiştir. Gökkuzgunların saksağan yuvaları gibi uygun olmayan yuva yerlerini ve uygun olmayan habitatları kullanmaları çalışma alanında bu türe yönelik bir koruma programının gerekliliğini ortaya koymaktadır.
