Pacific Black Duck - Taronga Zoo, Sydney Australia AIMG 8022

Turquiose browed motmot. AIMG_0471 Males apparently use their tail as a sexual signal, as males with longer tails have greater pairing success and reproductive success. In addition to this function, the tail is used by both sexes in a wag-display, whereby the tail is moved back-and-forth in a pendulous fashion. The wag-display is performed in a context unrelated to mating: both sexes perform the wag-display in the presence of a predator, and the display is thought to confer naturally selected benefits by communicating to the predator that it has been seen and that pursuit will not result in capture. This form of interspecific communication is referred to as a pursuit-deterrent signal. From en.wikipedia.org/wiki/Turquoise-browed_Motmot
