Freckled Duck (Stictonetta naevosa) Fact Sheet: Population & Conservation Status

Population estimates

• 11,000-26,000 individuals (Birdlife International 2016)
  • 7,300-17,000 mature individuals (Birdlife International 2016)
• Widely distributed but not abundant (Frith 1967)
  • Largest populations supported by a small number of permanent marshes (Frith 1967)
• Population trend (Birdlife International 2016 citing Wetland International – China Office 2006; Carboneras and Kirwan 2018; Kingsford, Wong, et al. 1999)
  • Considered relatively stable but probably declining over time; not globally threatened (Richard Kingsford, personal communication, 2019)
    • Abundance appears to fluctuate in response to El Niño/La Niña event oscillations (Southern Oscillation Index)
  • Declines in recent decades in regions where freshwater habitats are modified or destroyed for human activities
• See “Conservation status by Australian state,” below

IUCN

• Least Concern (2016 assessment) (Birdlife International 2016)
• Previous assessments (Birdlife International 2016)
  • 2012: Least Concern
  • 2009: Least Concern
  • 2008: Least Concern
  • 2004: Least Concern
  • 2000: Least Concern
  • 1996: Vulnerable
  • 1994: Vulnerable
  • 1988: Threatened

CITES

• Not listed (UNEP 2019)

Conservation status by Australian state

• Considered threatened in some Australian states (Grossek 2000; Carboneras and Kirwan 2018; Birdlife Australia 2018, and as noted)
  • New South Wales: Vulnerable
    • Also see Smith et al. (1994)
  • South Australia: Vulnerable
  • Victoria: Endangered (Game Management Authority 2016)

Government laws and regulations

• Protected throughout Australia (Grossek 2000; Carboneras and Kirwan 2018)
  • Environment Protection and Biodiversity Conservation Act of 1999
• Historically hunted as a game bird (Frith 1967)
  • Last open season in Victoria in 1975
    • Protected by Wildlife Act of 1975

Loss of freshwater habitat

• Greatest threat to Freckled Duck (Birdlife International 2016)
• Water extraction and draining wetlands (Birdlife International 2016)
  • Affects flooding of important inland wetlands
• Clearing of native vegetation (Smith et al. 1994)
• Climate change
  • Drought and rising salinities (due to saltwater intrusion) may affect this species (Smith et al. 1994; Chambers et al. 2005; Smith et al. 2009)
• Pollution of watersheds (Smith et al. 1994)
• Disturbance by humans in areas used for human recreation (Carboneras and Kirwan 2018)

Illegal hunting

• Freckled Duck protected but still likely to be shot by duck hunters (Corrick 1982; Norman and Norris 1982; Loyn 1991)
• Mistakenly shot due to similar appearance as game species (Birdlife International 2016)
  • Hunters now required to pass Waterfowl Identification Test (see below)
• Easy to shoot because of concentrations near water, especially during drought, and their low, circling flight (Marchant and Higgins 1990; Carboneras and Kirwan 2018)

Population monitoring

• Abundance counts conducted prior to hunting season (Carboneras and Kirwan 2018)
  • Began in Victoria in 1987
• Surveyed regularly across a third of the Australian continent each year and also during a national survey (e.g., Kingsford and Porter 2009; Kingsford et al. 2012)
• Community groups encouraged to report sightings (Grossek 2000)
• Also see this news story and the Eastern Australian Waterbird Survey

Area closures

• Australian Ministry can temporarily close wetlands to limit Freckled Duck’s exposure to illegal hunting (Loyn 1991; Grossek 2000)
  • More information: Game Management Authority of Victoria

Waterfowl Identification Test

• Licensed hunters must be able to correctly identify Freckled Duck on video (Loyn 1991; Grossek 2000; Carboneras and Kirwan 2018)
  • Mandatory, as of 1990 (Grossek 2000)

The Freckled Duck is the rarest duck in Australia.

The main threats to the Freckled Duck are the loss of freshwater habitat, and illegal and accidental hunting.
