ANTECHINUS

The Antechinus, although resembling the feral mouse, has distinct differences. Unlike mice, Antechinus lacks pungent odours and enlarged incisor teeth. They have canine-like teeth and are not known for gnawing cables or consuming stored food. As carnivores, they prefer insects and small lizards.

In Northern NSW, three species of Antechinus exist: the Brown Antechinus, Dusky Antechinus, and Yellow-footed Antechinus. All three species share a similar breeding pattern, with mating occurring in September. During this time, males exhibit aggressive behavior while searching for females.

Mating sessions can last up to six hours, repeated over a two-week period with multiple females. After mating, no male survives due to stress and the exhaustive mating ritual.

An interesting fact about Antechinus: They are known as the most sexually active animals in the world.

Approximately one month after mating, the female Antechinus gives birth to around 7-10 tiny babies. These babies cling to the mother’s nipples within an open pouch as she carries on with her activities, often dragging them on the ground for 5-8 weeks, depending on the species. It’s intriguing to consider how they manage to survive during this early stage of life. As they grow larger, they cannot travel with the mother anymore. Instead, they are left in a nest made of dry plant material, concealed in a hollow log or similar protected spot. At three months of age, they are weaned and begin traveling with their mother through the summer months. As winter approaches, they become solitary and venture their separate ways. Sexual maturity occurs at 11 months of age.

The Dusky Antechinus is found in mountainous areas with dense undergrowth of ferns and shrubs along the east coast of Australia and Tasmania. It utilizes its long claws and powerful limbs to dig for invertebrates, occasionally consuming fruits like blackberries. Currently, the Dusky Antechinus is not considered threatened; however, local populations in certain regions have declined due to habitat destruction caused by burning.

When dealing with mice in your home, please exercise caution, as you may unintentionally harm protected native wildlife. These creatures play a vital role in maintaining the delicate balance of biodiversity within our local forests.
