Abstract

Cinereous vulture is a threatened species. The second largest population of species in Western Palearctic region is found in Anatolia. Türkmenbaba mountain has one of the largest breeding colonies in Turkey. Detailed studies on Cinereous vulture colony in Türkmenbaba mountain was conducted between 2001-2005. Since then, there is no updated information on the population in the region. The aim of this study is to present current data regarding the population of the species in the area. Data on breeding pairs and fledglings number of Cinereous vulture were determined in the region. It was found that 28 pairs breed in Türkmenbaba mountain in 2016. Four nests out of the 28 which were detected as active in the beginning of breeding season were deserted three of them in the incubation and one of them in the nestling period . Breeding success ratio of Cinereous vulture colony was 85%. Additionally, it was determined that, 10 nests which were initially found during the 2001-2005 monitoring period, used by individuals in 2016 breeding season. The breeding pair numbers that were detected in this study was the highest ever recorded for the Türkmenbaba mountain vulture breeding colony. In order to obtain more detailed information on the population of species in the region, monitoring studies for a longer period should be conducted

Türkiye’nin en büyük Kara akbaba Aegypius monachus L. üreme alanlarından birine sahip olan Türkmenbaba populasyonuna yönelik güncel bir değerlendirme

Abstract

Kara akbaba tehlike altında olan bir türdür. Türün Batı Palearktik bölgede en büyük ikinci populasyonu Anadolu’da bulunmaktadır. Türkmenbaba dağı türün en büyük üreme kolonisinden birine sahiptir. Türkmenbaba dağı Kara akbaba kolonisine yönelik olarak 2001-2005 yılları arasında detaylı çalışmalar gerçekleştirilmiştir. Ancak türün populasyonunun bölgedeki durumu ile ilgili güncel veriler bulunmamaktadır. Bu çalışmanın amacı, Türkmenbaba dağında üreyen Kara akbaba kolonisi hakkında veri toplamaktır. Bu amaçla üreyen çift sayısı ve uçma başarısına ulaşan yavru sayısını belirlemeye yönelik olarak çalışmalar gerçekleştirilmiştir. Elde edilen verilere göre bölgede 28 çiftin ürediği tespit edilmiştir. Üreme dönemi başlangıcında aktif olarak belirlenen yuvalardan 4 tanesi terk edilmiştir 3 yuva kuluçka döneminde, 1 yuva ise yavru yumurtadan çıktıktan sonraki dönemde . Koloninin 2016 yılı için üreme başarısı %85’dir. Ayrıca 2001-2005 yılları arasında tespit edilen yuvalardan 10 tanesinin 2016 üreme döneminde de kullanıldığı görülmüştür. Bu çalışmada elde edilen Kara akbaba üreyen çift sayısı Türkmenbaba dağı için tespit edilen en yüksek sayıdır. Ancak populasyonun durumu hakkında kesin verilere ulaşmak için uzun yılları kapsayan takip çalışmalarının yapılması zorunludur
