At last Riko as finally asserted her dominance after ensuring to :
Thoroughly mark her chosen mates territory - check
Observe and approve of your chosen mates reproductive potential - check
Learn to forage and feed her mate - check
See off other males trying to approach her - check
Fend off potential other females from chosen mate - check
*in Attenborough's voice* The female here is the dominate in the relationship though is very picky over her chosen mate as they mate for life. She goes through a long and laborious mating procedure in order to first choose her mate from the selected breeding potential and then has several rituals she needs to perform before she fully commits, such as appearing aloof and disinterested one moment and clingy the next. Whoa betide any other female though that dares to approach her chosen mate once she has selected him as she will then fiercely defend her "property".
In up coming episodes we will finally be able to see her mating ritual which will cover several episodes.
