SP Myers 1974 03 Oreopholus ruficollis Tower Ulanos, Estancia Medeland, 35 Km S of Juandolo by road, Pinto de Medaniaga, Pucia de Bs Aires, Argentina 26 April cont'd Another words, the feeding behaviour is: stand peck Zonibyx, on the other hand, more typically does not run after the peering place, bending over directly to peck. Nor does it really stretch its neck that far while standing. I suggest that Oreopholus is searching over a wider radius than does Zonibyx (i.e. wider from the standing pt to the actual food being predated) and predict that Oreopholus will also be taking bigger food, if for no other reason than the bigger food will be more obvious than the little insect...
