Abstract
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.

Summary
Zenaida auriculata (Des Murs, 1847) (Aves: Columbiforme) is endemic to an area ranging from Antilles to Tierra del Fuego, passing through Brazil. This dove is popularly known as the eared dove (CÂNDIDO et al, 2008; SHIBATTA et al, 2009) and is found in fields, farms and urban areas (CÂNDIDO et al, 2008), where it can cause damage and potentially transmit pathogens (SHIBATTA et al, 2009). Little is known of the species of gastrointestinal parasites that infect these birds (MARQUES et al, 2007). The only study on the prevalence of helminths in Z. auriculata was conducted in Chile by González et al (2004); these authors encountered Killigrewia delafondi (9.4%), Raillietina sp. (1.7%), Heterakis gallinarum (0.4%) and Echinostomum sp. (0.9%)
