Marsupial

The Western Grey Kangaroo is one of the largest kangaroos. Breeding occurs throughout the year, peaking in summer. Gestation takes about 36 days. The joey leaves the pouch at about 11 months. The joey sucks from the mother until about 18 months.

The Red Kangaroo is the largest living marsupial. Adult males often fight each other in the breeding season, boxing with their front paws and kicking with their back legs. Females are sexually mature at about 18 months, males at about two years. A single joey is born at a time. The joey remains in the pouch for five to six months. The joey gradually spends time away from the pouch. Joeys are usually weaned at about one. Females can have three young with her at the same time - one as an embryo, one in the pouch and another out of the pouch still suckling.

Nocturnal. Shelters (sometimes in groups) in a grass nest they make in hollow logs or under grass tussocks, rocks or logs. Their flexible breeding pattern means they can breed quickly anytime between late winter to late summer when there is enough food. Dunnarts can have 2 to 3 litters per season with up to 10 young per litter. The young are weaned at 10 weeks. Dunnarts have short sharp teeth suited to crunching insects and spiders. Their scats have visible insect remains. The use of agricultural pesticides could affect their survival.

Active mostly from dusk to dawn, in small or large groups (mobs). Shelters under trees or shrubs. Can breed at any time of the year but mostly in summer. Gestation takes about 36 days. The joey leaves the pouch at about 11 months of age but suckles from the mother until about 18 months old, and by then another young may be in the pouch. Kangaroos can co-exist with sheep and cattle (except for times of drought or overstocking) as they prefer different plant foods.

Active at night. Can breed throughout the year, but mostly between July to November. Pregnancy lasts just 12 days, so they can produce up to five litters of young per year, with an average litter size of two. Can breed after 4 months of age. Average lifespan is 18 months to 2 years. Males need 13-20 hectares while females need 2-3 hectares.

Similar to Fat-tailed Dunnart. Shelters in hollow logs or under grass tussocks or rocks. Sometimes shelters in groups overnight and in winter. Female may live to breed a second year but the male usually dies after mating. This species appears to benefit from periodic burning of its habitat.

Nocturnal. Sleeps in tree hollows or similar protected places, including ceilings of buildings. The most abundant Australian possum, often living with humans. Can live for 11 years in the wild. Starts breeding at 1 year of age, with usually a single young born. The mother needs to take care of the young for at least 7 months.
