The big cats rubbed, sniffed, pawed, and otherwise thoroughly enjoyed the designer cologne.
"Calvin Klein Obsession for Men clearly passes the sniff test among the WCS Bronx Zoo's big cat population," said Thomas. "More importantly, this work is a great example of how The Wildlife Conservation Society's Living Institutions and Global Conservation Programs work together to save wildlife and wild places."
As predicted, the cologne is doing a great job at attracting jaguars to the hidden camera setup.
The images show individual jaguars lingering around a cloth treated with the cologne and repeatedly sniffing it. One pair of jaguars even shows some very rarely seen mating behavior, so the smell seems to turn these animals on.
"Jaguars are highly elusive creatures and for years WCS researchers struggled to develop more effective methods for estimating how many jaguars were in the forest, hidden amongst the ancient Maya temples," said Roan McNab, WCS Guatemala Country Director. "Now, due to the fact that jaguars love Obsession for Men, WCS field conservationists are getting more precise estimates of jaguar populations."
