We describe the first predation record of an undescribed adult male tarantula from the genus Euathlus in a juvenile austral thrush (Turdus falcklandii Quoy and Gaimard, 1824) (Aves: Turdidae) in central Chile. The precise moment of predation was not observed; it could have been an opportunistic event or active hunting. In support of the later alternative, this undescribed species of Euathlus has been relatively frequently seen walking on tree trunks. These incidental observations raise the question of how important Euathlus is as a predator of juvenile birds.
