Australia's worst drought in a hundred years is driving its kangaroos into cities in search of food and water, experts say.
In Canberra, referred to as the Bush Capital for its pockets of parklands scattered throughout the city, residents encounter the common sight of eastern gray kangaroos on the streets.

After several years of dry conditions, vegetation has been grazed down to nothing—leading to the unusual spectacle of kangaroos hopping around the lush grounds of the lakeside home of Australia's Governor General, Sir Michael Jeffery.
Canberra's urban kangaroo sightings have been complemented by reports of greater numbers of kangaroos in other cities and towns in the southeast of Australia, apparently driven there in search of food. (See a map of Australia.)

Brendan Mackey, director of of the Australian National University's WildCountry research unit, says it is "quite logical" to see more kangaroos moving into urban areas seeking sustenance.
"The kangaroo's biology is geared to take advantage of the good times," Mackey said. "So when times are good they reproduce and are very fecund. When the signals turn negative they stop."
Droughts cause a competition for scarce resources, so when times start to get tough, kangaroos compete with sheep and cattle for food and water, Mackey said.
The outskirts of Canberra and other major cities such as Sydney and Melbourne still have relatively plentiful resources—without the other competitors that are usually found in the bush.
"Because Australia naturally has a boom and bust environment, you have large droughts and flooding rains. From year to year rainfall is quite unreliable. In order for an animal to live in this environment they have to have a strategy to survive," Mackey said.
