Arap Bülbülü’nde (Pycnonotus xanthopygos) Bazı Seslerin Fiziksel Özellikleri ve İşlevsel Anlamı

Öz

Çalışmada, Arap bülbülü, Pycnonotus xanthopygos'un üreme mevsimlerinde kullandığı bazı ötüşlerin fiziksel özellikleri, bu ötüşlerin hangi durumlarda kullanıldığı ve ne anlama geldiğinin belirlenmesi amaçlanmıştır. Sıklıkla sergilenen ötüşlerin teritoryal, lokalizasyon, alarm, yiyecek arama, selamlama ve dinlenme süreçlerinde 6 farklı sinyal şeklinde kullanıldığı belirlenmiştir. Sinyallerin taşıyıcı frekansı 1,27 (min) ile 5,35 (maks) kHz arasında değişmekte ve sinyaller arasında olduğu kadar şekil, hece sayısı ve elementler arasında da farklılıklar olduğu tespit edilmiştir. Arap Bülbülü’nün sergilemiş olduğu iletişim sistemi hakkında bilgi elde etmenin yanısıra, yerleşim alanlarında yayılış göstermesi ve dolayısıyla insana alışık olması itibariyle hem akustik hem de davranışsal konuları incelemek için iyi bir model tür olabileceği sonucuna varılmıştır.
