Call for 'Approach and Scan for Danger' (AUDIO)
Caption
Dr. Suzuki and colleagues could demonstrate that ABC calls signifies 'scan for danger', for example when encountering a perched predator, whereas D calls signify "come here," for example when discovering a new food source, or to recruit the partner to their nest box. Tits often combine these two calls into ABC-D calls such as when approaching and deterring predators. When these two calls are played together in the naturally occurring order (ABC-D), then birds both approach and scan for danger. However, when the call ordering is artificially reversed (D-ABC), birds do not respond.
