Abstract

It is known that roads have an ecological effect on wildlife, not only in negative but also in positive ways. Few studies provide information about the effect that roads have on bird population levels. In this study, we investigate the effect of roads on the breeding success, nest tree, and nest characteristics of the Eurasian Magpie (Pica pica). We compared the magpie breeding success of nesting along a paved highway with those along a dirt road. In addition, the nest and nest tree characteristics were measured for the two road types. We found that breeding success is significantly higher near highway than dirt road and that nests were wider and larger near dirt road than those near highway. According to our results, the magpie is positively affected by the highway. This may be explained by food supply and, more likely, by lower predator pressure.

Özet

Yolun doğal yaşam üzerine hem olumlu hem de olumsuz yönde etkisi olduğu bilinmektedir. Bununla birlikte kuş populasyonları üzerine yolun etkisi ile ilgili olarak az sayıda çalışma olduğu görülmektedir. Bu çalışmada yolun saksağan (Pica pica)’ların üreme başarısı ve yuva özelliği üzerine etkisi araştırılmıştır. Üreme başarısı üzerine yol etkisinin belirlenebilmesi için saksağan bireylerinin tali yol ile bölünmüş otoyol kenarına yaptığı yuvalardaki üreme başarıları karşılaştırılmıştır. Aynı zamanda iki yol kenarında bulunan yuvaların yuva özelliklerinin belirlenmesine yönelik ölçümler gerçekleştirilmiştir. Elde edilen verilere göre bölünmüş otoyol kenarında yuvalanan saksağan bireylerinin üreme başarılarının belirgin bir biçimde fazla olduğu tespit edilmiştir. Ayrıca yuva çapının ve yuva hacminin tali yol kenarındaki yuvalarda daha fazla olduğu belirlenmiştir. Çalışmalar sonucunda saksağan bireylerinin yol varlığından olumlu yönde etkilendiği söylenebilmektedir. Bu durum bölünmüş otoyollardaki daha fazla besin kaynağı ve düşük avcı baskısı ile açıklanabilir.
