The blue-crowned motmot (Momotus momota) is a large, omnivorous, Neotropical bird. Momotus momota demonstrates a variety of life history traits that could make the bird more vulnerable to ambush predators as well as adaptations to signal to, and deter attack by, ambush predators. Like other motmots, M. momota performs an exaggerated tail-wagging motion when presented with a visual predatory stimulus. I studied the different reactions elicited by four treatments to examine the importance of the signal receiver as a predator that had been visually located by the motmot. I presented either an avian model or an avian call played back to motmots and observed reactions. Motmots were significantly more likely to wag-display (p = 0.0009) upo...
