Giant panda Fu Ni has a massive crush on Wang Wang and he can hardly bear to be away from her.
Unlike the human dance of attraction, flirting in the panda world is relatively black and white.
Fu Ni has been bumping and grinding as she marks her scent around the enclosure at Adelaide Zoo while Wang Wang is ‘rutting’ -- power-walking to build strength and energy.
Peeping over the enclosure is a team of panda sexperts who are watching and listening.
“The building has also come alive with panda chatter -- Fu Ni has been chirping and bleating away, even when Wang Wang is not around, while Wang Wang has started his first bleats of the season,” acting senior panda keeper Lucy Catt said.
“These vocalisations, used between pandas in the lead up to the breeding season, will continue to increase over the coming days before the building becomes eerily quiet just prior to ovulation.”
Fu Ni’s period of fertility will last just 36 hours and the team is checking her urine and cell samples to make sure they don't miss it.
If Wang Wang doesn't make a move naturally, the artificial insemination team will swoop in.
