A Preliminary Investigation on Ticks (Acari: Ixodidae) Infesting Birds in Kizilirmak Delta, Turkey

Abstract

Ticks are mandatory blood-feeding ectoparasites of mammals, birds, reptiles, and even amphibians. Turkey has a rich bird fauna and is located on the main migration route for many birds. However, information on ticks infesting birds is very limited. In the present study, we aimed to determine ticks infesting birds in Kizilirmak Delta, Turkey. In 2014 autumn bird migration season, a total of 7,452 birds belonging to 79 species, 52 genera, 35 families, and 14 orders were examined for tick infestation. In total, 287 (234 larvae, 47 nymphs, 6 female) ticks were collected from 54 passerine birds (prevalence = 0.72%) belonging to 12 species. Ticks were identified as Amblyomma sp., Dermacentor marginatus (Sulzer), Haemaphysalis concinna Koch, Haemaphysalis punctata Canestrini and Fanzago, Hyalomma sp., Ixodes frontalis (Panzer), and Ixodes ricinus (L). The most common tick species were I. frontalis (223 larvae, 23 nymphs, 6 female) followed by I. ricinus (3 larvae, 12 nymphs) and H. concinna (4 larvae, 6 nymphs). Based on our results, it can be said that Erithacus rubecula (L.) is the main host of immature I. frontalis, whereas Turdus merula L. is the most important carrier of immature stages of some ticks in Kizilirmak Delta, Turkey. To the best of our knowledge, most of the tick-host associations found in this study have never been documented in the literature.
