Occurrence of gastrointestinal and renal helminths in Zenaida auriculata (Des Murs, 1847) trap-captured from Brazil. 
This study aimed to determine the prevalence of gastrointestinal and renal helminths from naturally infected Zenaida auriculata captured in Londrina, Paraná State.  Two hundred and one Eared doves were trapped and the gastrointestinal and renal helminths were collected and identified according to morphological structures.  One hundred and sixteen (57.71%) doves were parasitized by helminths with specific prevalences for Ornithostrongylus quadriradiatus in 50 doves (24.88%), Ascaridia columbae in 47 (23.38%), Paratanaisia bragai and P. confusa in 34 (16.92%), Tetrameres fissispina in 17 (8.46%), Synhimantus nasuta in 14 (6.47%), Brachylaima mazzantii in 4 (1.99%) and Raillietina allomyodes in 2 doves (1.00%).  Seventy four/201 (37.00%) birds were infected with only one species, and 96/201 (48.00%) pigeons were infected with nematodes.  The association between different classes of helminths occurred in 40/201 (20.00%) animals.  The results showed statistically differences between the presence of nematode (p = 0.00001) and trematode species (p ≤ 0.05) in the doves, and there was an association between the local of capture and the presence of trematodes and A. columbae (p ≤ 0.05).  This study is the first to report the infection of Z. auriculata from Brazil with O. quadriradiatus, A. columbae, T. fissispina, S. nasuta, R. allomyodes, P. bragai and P. confusa.
