Reaching of the trunk to the genitals of a female, putting the trunk fingers inside her genitalia and making audible sucking sounds.
A female with assymetrical tusks is coming into estrus and is being followed by a medium sized male who is testing her Trunk-to-Genitals. While we have often observed a male put the tip of his trunk inside a female's genitals we have not documented a male so actively do so with such an audible sucking sound. After doing this several times the male stands engaged in Trunk-Suction and then gives a vigorous spray - as if emptying all that he had sucked into his trunk from the female's genitalia.
