Editing Cockatoo (section)

===Predators and threats===
The [[peregrine falcon]] and [[little eagle]] have been reported taking galahs and the [[wedge-tailed eagle]] has been observed killing a sulphur-crested cockatoo.<ref name=Forshaw29/> Eggs and nestlings are vulnerable to many hazards. Various species of monitor lizard (''[[Varanus]]'') are able to climb trees and enter hollows. Other predators recorded include the [[spotted wood owl]] on Rasa Island in the Philippines; the [[Morelia amethistina|amethystine python]], [[black butcherbird]] and rodents including the [[giant white-tailed rat]]<ref>{{Cite journal|last=Wood GA|year=1987|title=Further field observations of the Palm Cockatoo ''Probosciger aterrimus'' in the Cape York Peninsula, Queensland|journal=Corella|volume=12|issue=2|pages=48–52|url=http://www.aainsects.com.au/Pdf-papers-aainsects/Bird/bird-Cacat-3.pdf|access-date=17 December 2009|archive-date=21 September 2016|archive-url=https://web.archive.org/web/20160921140624/http://www.aainsects.com.au/Pdf-papers-aainsects/Bird/bird-Cacat-3.pdf|url-status=dead}}</ref> in Cape York; and [[common brushtail possum|brushtail possum]] on Kangaroo Island. Furthermore, galahs and little corellas competing for nesting space with the glossy black cockatoo on Kangaroo Island have been recorded killing nestlings of the latter species there. Severe storms may also flood hollows drowning the young and termite or borer activity may lead to the internal collapse of nests.<ref name=Cam149>{{Harvnb|Cameron|2007|p=149}}.</ref><!-- cites all para-->

Like other parrots, cockatoos can be afflicted by [[psittacine beak and feather disease]] (PBFD). The viral infection causes feather loss and beak malformation and reduces the bird's overall immunity. Particularly prevalent in sulphur-crested cockatoos, little corellas and galahs, it has been recorded in 14 species of cockatoo to date. Although unlikely to significantly impact on large, healthy populations of birds in the wild, PBFD may pose a high risk to smaller stressed populations.<ref name="gov">{{cite web|url=http://fedlaw.gov.au/ComLaw/Legislation/LegislativeInstrument1.nsf/previewlodgmentattachments/81FCCCA0AB589760CA25718E00044623/$file/F2005L02255.htm |archive-url=https://web.archive.org/web/20110706142728/http://fedlaw.gov.au/ComLaw/Legislation/LegislativeInstrument1.nsf/previewlodgmentattachments/81FCCCA0AB589760CA25718E00044623/%24file/F2005L02255.htm |archive-date=6 July 2011 |title=Threat Abatement Plan for Psittacine Beak and Feather Disease Affecting Endangered Psittacine Species |last=Borthwick |first=David |date=May 2005 |website=Department of the Environment and Heritage website |publisher=Department of the Environment and Heritage, Commonwealth of Australia |access-date=7 December 2009 |url-status=dead }}</ref>

A [[white cockatoo]] and a sulphur-crested cockatoo were found to be infected with the protozoon ''[[Haemoproteus]]'' and another sulphur-crested cockatoo had the [[malaria]] parasite ''[[Plasmodium]]'' on analysis of faecal samples at Almuñecar ornithological garden in [[Granada]] in Spain.<ref name=VP09>{{Cite journal|last=Cordon|first=GP|author2=Hitos Prados A |author3=Romero D |author4=Sánchez Moreno M |author5=Pontes A |author6=Osuna A |author7=Rosales MJ |year=2009|title=Intestinal and haematic parasitism in the birds of the Almunecar (Granada, Spain) ornithological garden|journal=Veterinary Parasitology|volume=165|pmid=19682800|issue=3–4|pages=361–66|doi=10.1016/j.vetpar.2009.07.027}}</ref> Like amazon parrots and macaws, cockatoos frequently develop cloacal [[papilloma]]s. The relationship with malignancy is unknown, as is the cause, although a parrot [[Papillomaviridae|papilloma virus]] has been isolated from a [[grey parrot]] with the condition.<ref>{{cite conference |vauthors=Stedman NL, Latimer KS, Rakich PM |title=Cloacal papillomas in psittacine birds: A retrospective histopathologic review |book-title=Proceedings of International Virtual Conferences in Veterinary Medicine: Diseases of Psittacine Birds |year=1998 |journal=International Virtual Conferences in Veterinary Medicine |publisher=College of Veterinary Medicine, University of Georgia |location=Athens, GA |url=http://www.vet.uga.edu/vpp/archives/ivcvm/1998/stedman/index.php |access-date=1 March 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110720084405/http://www.vet.uga.edu/vpp/archives/ivcvm/1998/stedman/index.php |archive-date=20 July 2011 |df=dmy-all }}</ref>
