Abstract:We present the first report of reverse mounting in the Bearded Vulture (Gypaetus barbatus). The reverse mounting, which occurred in the Pyrenees of northeastern Spain, took place between the female and the alpha male in a polyandrous trio. The function of reverse mountings is discussed in relation to the previously reported high frequency of male-male mountings in this raptor species.
