The zebra finch occurs in two geographical races across most of the Australian continent and on some of the Lesser Sundra Islands. Originally, it inhabited open grasslands with individual bushes and trees, but it has secondarily settled in a variety of habitats, including human-made environments such as gardens, pastures, and agricultural landscapes, as a cultural follower. The birds have adapted in various ways in their physiology and behaviors to the fluctuating climate. Many characteristics of their lifestyle, such as the constant pairing of mates, early breeding maturity, and year-round breeding readiness – they take advantage of the most favorable temperature and rainfall conditions for breeding in each area – are of great biological significance and contribute to the preservation of the species. To cope with the diverse dangers that the birds face in the form of...
