a species has a picture drawback when the overwhelming majority of scientific papers overlaying it embody the phrase “invasive” of their title. Such is the destiny of the Rose-ringed Parakeet (paper title adopted by an excerpt or spotlight):
Biology and impacts of Pacific Island invasive species. 15. Psittacula krameri, the rose–ringed parakeet (Psittaciformes: Psittacidae) (“RRP are seed predators and barely seed dispersers; their flock-foraging conduct can lead to extreme injury to orchard and discipline agricultural crops together with tropical fruit and corn”)
Nesting improvements permit inhabitants development in an invasive inhabitants of rose–ringed parakeets (describing how the parakeets, as a substitute of counting on pure cavities, dig their very own tree cavities or use the stick nests of one other species)
World invasion success of the rose–ringed parakeet (“The common presence of Rose-ringed Parakeets in city parks and gardens could change into so regular to our youngsters … that parakeets change into no extra thrilling than a typical pigeon”)
Seasonal results on the thermoregulation of invasive rose–ringed parakeets (Psittacula krameri) (“Our outcomes recommend that this species is physiologically and behaviorally geared up to deal with a variety of climatic conditions and this partly explains their international success as an invader species”)
Improved surveillance for early detection of a possible invasive species: the alien Rose–ringed parakeet Psittacula krameri in Australia (“In Australia, it’s categorised as an ‘excessive menace’, but captive people ceaselessly escape into the wild.”)
Essential assessment of potential management instruments for decreasing injury by the invasive rose–ringed parakeet (Psittacula krameri) on the Hawaiian Islands (“We advocate an built-in pest administration technique together with deadly and non-lethal instruments”)
Diets of Kauai’s invasive rose–ringed parakeet (Psittacula krameri): proof of seed predation and dispersal in a human-altered panorama (“land managers in agricultural, city, and pure areas must be involved with the present enlargement of those invasive birds on Kauai and elsewhere”)
And lots of the papers not containing the phrase “invasive” of their titles aren’t optimistic both:
An estimation of Rose–ringed Parakeet (Psittacula krameri) depredations on citrus, guava and mango in orchard fruit farm (“Reliance on the standard and efficient pest administration strategies has no efficient impression to scale back parakeet depredations”)
Data of deadly assaults by Rose–ringed Parakeets Psittacula krameri on native avifauna, which in its summary describes “six deadly assaults by Rose-ringed Parakeets Psittacula krameri, probably the most profitable invasive avian species in Europe, on Home Sparrows Passer domesticus and Blue Tits Cyanistes caeruleus in Barcelona, Catalonia, Spain. Sparrows and tits have been attacked via a 1.5-cm mesh while trapped inside funnel traps. Assaults have been carried out by a couple of Rose-ringed Parakeets. An osteological examination of the Home Sparrow skeletons revealed that a lot of the accidents have been brought on by the drilling and crushing of cranium bones.”
Rose–ringed parakeet nesting in Hawaii: A possible agricultural menace (advice within the paper: “Efforts be made by the correct State authorities to seize or eradicate all Rose-ringed Parakeets within the wild in Hawai’i.”
Rose–ringed Parakeets (Psittacula krameri, Scopoli, 1769) in Turkey: is the menace rising sooner or later? which argues for “the necessity for long-term administration, notably in coastal cities the place already-established populations are rising in measurement”.
In fact, the lobbying group of Rose-ringed Parakeets, in frequent posts on their social community “Rose Social”, highlights the few optimistic papers resembling
Alien rose–ringed parakeets (Psittacula krameri) assault black rats (Rattus rattus) generally leading to dying (by which parakeets certainly assault black rats approaching their nests. Whereas most rats merely flee, just a few fall down timber and die, doubtlessly benefiting native chook species).
Nonetheless, such papers don’t preserve people from discovering methods of limiting the unfold of the species, lined in papers resembling
An analysis of Diazacon as a possible contraceptive in non-native rose–ringed parakeets (“diazacon has potential for fertility management on this species if an acceptable formulation and supply system is developed for free-living populations”)
That mentioned, all pictures proven on this put up have been taken in Sri Lanka (in March 2025), the place the Rose-ringed Parakeet is a local, not an invasive species.
