Ticks on birds from Cerrado forest patches along the Uberabinha river in the Triângulo Mineiro region of Minas Gerais, Brazil

We herein describe ticks parasitizing birds in forest fragments along the Uberabinha River, a major watercourse that cuts through patches of remnants of Brazilian savannah in Uberlândia, Minas Gerais, Brazil. Overall 352 birds from 62 species, overwhelmingly, Passeriformes, were captured with mist-nets. The most abundant bird species was Basileuterus hypoleucus (n=36), followed by Lanio penicillata (n=24) and Thalurania furcata (n=23). Thirty one birds, all Passeriformes, were found infested with 56 ticks from which 12 were larvae and 44 nymphs, all from the Amblyomma genus. Highest infestation prevalence was found on Taraba major (66.6%), Thamnophilus pelzeni (60%) and Saltator maximus (50%). The mean intensity of tick infestation was low (1.8 tick per infested bird) with most of the parasites located on the neck (60%) of birds, followed by the head (20%). All larvae were attached to the skin around the eyes of birds. Amblyomma nodosum was the most numerous tick species found attached to birds (n=23 nymphs, 52.3% of nymphs) followed by Amblyomma longirostre (n=5, 11.4% of nymphs).
