Abstract

This study analyzes the prevalence and mean intensity of infestation of ticks on birds captured in ESEC-Pirapitinga (180 20’S e 450 17’WGr), in Três Marias, Minas Gerais, Brazil. Of a total of 1.295 birds captured, distributed in nine orders, 28 families and 92 species, 165 (12.7%) individuals were parasitized by ticks. Of these 160 (97%) belonged to the order Passeriformes and only 5 (3%) belonged to the grouping of non-passerines. We identified five tick species: Amblyomma longirostre (n = 274) was the most common species followed by Amblyomma parvum (n = 43), Amblyomma nodosum (n = 39), Amblyomma ovale (n = 24) and Rhipicephalus sanguineus (n = 7). The average infestation was 2.7 ticks by bird. Only 16 (10%) birds were infected with more than 5 ticks, while 97 (58.8%), birds were infected with a single tick. Also present in this study, some new records of A. longirostre. A. parvum, A. nodosum, A. ovale and R. sanguineus parasitizing birdscn
