First record of predation of the paper nautilus <i>Argonauta nouryi</i> (Cephalopoda: Argonautidae) by the Common Black Hawk <i>Buteogallus anthracinus</i> (Accipitriformes: Accipitridae)
Abstract
Predation of cephalopods by non-marine birds is rare, especially within the Order Accipotriformes. Observations took place in situ and identification of Argonauta nouryi was entirely based on the shell form. The predation of the paper nautilus, A. nouryi, by the Common Black Hawk, Buteogallus anthracinus, is reported for the first time at the Murciélago Sector of the Santa Rosa National Park, Guanacaste, Costa Rica. This represents the first known bird predator of this species within the country.Downloads
