During the heat of the day, grey kangaroos (Macropus giganteus) prefer to loll around in the shade. They're not silly. They rest in the cool of the forest until the sun starts to go down and then they emerge to feed among the long shadows.
When the weather is mild, they come out much earlier. And where they are used to people they may also be active at any time of the day. (At Anglesea golf club, they swarm all over the fairways and interrupt play.)
I spotted this mob near the You Yangs, SW of Melbourne. They were vigilant but not obviously upset by me and/or the camera. No one was playing golf nearby.
