That Time CIA Used Tiger Droppings as a Covert Tracking Device

#InternationalTigerDay
#GlobalTigerDay
There are only approx 3,900 wild tigers left in the world today. However, during the Vietnam War the Indochinese tiger population was healthy & thriving, providing us a creative way to covertly track movement of North Vietnamese & Viet Cong.

#GlobalTigerDay
During the war, the US needed to monitor opposition location & movement.
CIA scientists invented a seismic intruder detection device: 1.usa.gov/1KyESWn
It could be strategically placed to monitor movements up to 300 meters away.
That’s where tigers came in.
#GlobalTigerDay
Our scientists had to disguise the tech so it would blend into the natural habitat & not be disturbed.

As tigers are native to Vietnam & were found in larger numbers 50 years ago, they were ideal cover.

Detection device was designed to look like tiger droppings.
#GlobalTigerDay
Fueled by tiny power cells & with a built-in antenna, device tracked movement by detecting & counting vibrations from passing people, vehicles, & animals. Data would be relayed via coded pulses

#Khashoggi Case Thread: I am going to ‘pin’ this post to use it as an ‘Info Thread’ on the #Khashoggi Case. I am in #Turkey. I’ve been following the case closely and with access to sources & experts here. This is a very ‘sensitive’ criminal case due to ‘Diplomatic Booby Traps’!!!
The Evidence Obtained Outside Cameras will not show any evidence of ‘tempering’ but other than license plates of dozens of diplomatic cars (Many with tinted windows-large trunks) with related time stamp, drivers Info, model/year: Nothing.
#Turkish Intel-Investigative Bodies also have the list of all Diplomatic & Private Saudi & “other significant’ Planes in #Turkey for the period of ‘interest.’ Many of the Target airports have their own security cameras & related evidence.

Sadly, of the large carnivore species, more than 60% of them are threatened. Of the 17 showing widespread population declines, they now live in only 47% of their historical ranges. The tiger, for example, could have lost 95% of its historical range science.sciencemag.org/content/343/61…
There are fewer than 3,900 tigers left in the world today due to widespread habitat loss, historic overhunting (thanks to us Brits), #humanwildlifeconflict and, more recently, #illegalwildlifetrade. Sadly, tigers are desired for their skins as rugs & their parts for medicine
Tigers continue to decline in many parts of south-east Asia but their population seems to be fairing better in India due to strictly enforced protected areas & efforts from the Global Tiger Forum 🐯hindustantimes.com/environment/ti…
