Effects of the Recent World Invasion by Ring-Necked Parakeets Psittacula krameri

Droppings by ring-necked parakeets may alter the herbaceous vegetation under the roost but direct cause–effect relationships for this phenomenon are hard to assess if no data about floral composition before the time of invasion is available

Scholarcy highlights

  • Droppings by ring-necked parakeets may alter the herbaceous vegetation under the roost but direct cause–effect relationships for this phenomenon are hard to assess if no data about floral composition before the time of invasion is available
  • Ring-necked parakeets may have economic impacts, being responsible for crop damage, as well as societal impacts; three bird strikes with airplanes involved this species in England
  • The ring-necked parakeet is a potential reservoir of a plethora of diseases transmittable to humans and wildlife
  • No data concerning ecosystem recovery after the removal of ring-necked parakeets is available, as eradication and numerical control programmes are often hampered by the emotional affiliation which links humans to these bright birds
  • BOU proceedings, the impacts of non-native species
