Hi @RodDeb, probably a fair indication that his molars are getting quite worn down! In their last few years, kangaroos eat madly because their molars aren't busting open many plant cells, so grass keeps goes through them without providing as much nutrition as a younger adult can obtain. Some of them spend a few weeks living in someone's backyard (if there is no dog, and they are left alone) because the plants are softer, more nutritious and less heavily grazed there, before moving on.
It is a classic demonstration of 'predation sensitive foraging' and the 'landscape of fear', in that the animals that venture closest to the danger are the ones in declining condition. So the predators get to eat mainly the animals of intermediate fatness between those in good condition and those that have died of starvation.
