We try to understand what the meaning of all this is, why a Hirex would waste time and energy and expose himself to predators by singing such a loud

Weissman and his team recorded the songs of male hyraxes during mating season and they analyzed their structure.

We found in fact that the song is actually an advertisement for the male quality.

And in this song, the rarest and most interesting element is a snort.

It sounds like this, that's just like a snort.
