Abstract

HERRERA R., Jorge Moisés  and  APARICIO U., Karla. Report of attack of a Boa constrictor (Serpentes: Boidae) on Tyto furcata (Birds: Tytonidae) in Pacora, Panama. Huitzil [online]. 2019, vol.20, n.2, e519.  Epub Mar 10, 2019. ISSN 1870-7459.  http://dx.doi.org/10.28947/hrmo.2019.20.2.403.

Small birds constitute a significant portion of the Boa constrictor diet. There are few reports on the consumption of larger birds, even fewer of intraguild predation (among top predators). We report the unusual finding of a barn owl, Tyto furcata, depredated by an approximately 220 cm Boa constrictor on January 25, 2017. The discovery was made on the grounds of the Comisión Panamá - Estados Unidos para la Erradicación y Prevención del Gusano Barrenador del Ganado (COPEG) (coordinates 09°05’16.7” N, 79°17’10.8” W), in the community of Pacora, Panama. This report contributes to the understanding of ecological relationships between two rarely documented predators.

Keywords : intraguild predation; opportunist; passerines; diet; ecological relationships.
