Magpie Goose (Anseranas semipalmata) Fact Sheet: Distribution & Habitat

Distribution

Geographic areas

(BirdLife International 2016, except as noted)

  • Australia
    • Mainly northern and eastern Australia
      • Northern Australian contains the major breeding and dry season refuge areas (Peter Bayliss, personal communication, 2018)
    • Southern Australia
      • Resident population west of Melbourne
      • Reintroduced to several locations in southern and southeastern Australia (Nye et al. 2007)
        • Nearly disappeared from southern regions
          • See “Historic distribution,” below
    • Reported outside usual range, especially during extended dry seasons in northern Australia (Carboneras and Kirwan 2017)
      • Tasmania (Johnsgard 1965; Frith 1967; Carboneras and Kirwan 2017)
  • Southern New Guinea (Indonesia and Papua New Guinea)

Proximity to coast

  • Usually found within 300 km (186 mi) of the coast (Frith 1967; Carboneras and Kirwan 2017)
  • Occasionally occurs in more inland, arid regions (Frith and Davies 1961; Heron 1973; Kingsford and Porter 1993)
    • Flood events fill ephemeral lakes in central Australia (Kingsford and Porter 1993)
      • Breeding can occur if rainfall is sufficient (Frith 1967)
        • High gosling mortality when water disappears too early

Historic distribution

  • Abundant in southeastern Australia prior to European settlement (Nye et al. 2007; Olsen 2010)
    • Included breeding colonies (Frith 1967)
    • Locally extinct in this region by 1920, due to:
      • Wetland damage and drainage
      • Overhunting
    • Sightings on east coast in late 1970s and early 1980s
  • Historically, more abundant in northern than southeastern Australia (Nye et al. 2007)
  • Records as far south as Tasmania (Nye et al. 2007)
    • No evidence of breeding in Tasmania
  • Also see Frith and Davies (1961) for discussion

Habitat

General

  • Often live near water (Frith 1967)
    • Spend relatively little time with body in water
      • Walk on exposed ground and over vegetation
      • Swim or wade in shallow water
  • Amount of suitable habitat varies greatly from year to year (Delaney et al. 2009)
    • Dependent on rainfall

Floodplains of tropical rivers

(Johnsgard 1978)

  • Marshes (Wilson 1997; Carboneras and Kirwan 2017)
    • Use mud habitat more often to grub for water chestnut bulbs when tall sedge vegetation dies back during dry conditions
  • Open water (Wilson 1997)
    • Permanent lagoons
    • Dams
  • Grasses (Carboneras and Kirwan 2017)
    • Forage in higher areas of a floodplain (Frith 1967; Johnsgard 1978)
  • Trees (e.g., tea tree [Melaleuca], Eucalyptus, mangroves) (Frith and Davies 1961; Marchant and Higgins 1990)
    • Used for roosting (Frith and Davies 1961)
    • Perch up high, often on slim branches (Delacour 1954)
  • Agricultural habitats
    • Pasture and rice fields (Marchant and Higgins [1990] citing Gowland [1988])
    • Used when food on irrigated lands better than in degraded habitats or during drought (Wilson 1997)
      • Prefer sites close to permanent water sources

Preferred habitat

  • Shallow, semi-permanent wetlands (Marchant and Higgins 1990; Carboneras and Kirwan 2017)
  • Areas with dense tall spike-rush (Eleocharis sphacelata), water chestnut (E. dulcis) and abundant grasses (Frith 1967)
    • Spike-rush and wild rice (Orzya) are this bird’s primary breeding habitat (Johnsgard 1978)
