In April 2016, researchers set up 10 of these water stations on the ground and up in the trees on a large piece of land with a sizable population of koalas. They also installed a surveillance system to see how much the koalas were using the Blinky Drinkers.
What they found was really surprising: The koalas drank a lot, even waking up during the day, when they normally sleep, to go drink water from the stations on the ground. All of the Blinky Drinkers were visited - 193 times total. And this was in the fall and winter seasons, when the heat isn't so severe.
