Male azure-winged magpies emit distinctive songs to court females, but these vocalizations also draw et predatory wasps that prey on the magpies'eggs. Researchers Sofia Moreno and Carlos Hernandez speculated whether the songs alone were enough for wasps to find the magpies or if the wasps also relied ceon visual cues from the birds . similar to how some predators use sight in addition to sound to locate their prey. In their study, Moreno and Hernandez placed two decoy nests in a magpie nesting area. One decoy emitted magpie songs, and the other displayed visual magpie cues alongside the songs. Their investigation led them to conclude that visual cues do not act as an additional attractant for the egg- predatory wasps. Which outcome from their experiment, if verified, would most convincingly affirm Moreno and Hernandez's assertion? A. Few wasps were attracted to both decoys, though a slightly higher number were observed at the decoy that combined songs with visual cues. B.Wasps approached the decoy combining songs and visual cues only during times when visual cues were prominently displayed. C. A higher number of wasps were drawn to the decoy that solely played magpie songs than to the decoy that combined songs with visual cues. D. The decoy that combined magpie songs with visual cues attracteddfewer wasps at times of minimal visual display but more wasps when the visual cues A were more obvious.
