Overlap and competition for nest holes among eclectus parrots, palm cockatoos and sulphur-crested cockatoos

We examined the extent of overlap in the characteristics of nest holes used by eclectus parrots (Eclectus roratus), palm cockatoos (Probosciger aterrimus) and sulphur-crested cockatoos (Cacatua galerita) in patches of rainforest and woodland in and around Iron Range National Park, Cape York Peninsula, Australia. Eclectus parrots nested only in rainforest and palm cockatoos nested mostly in eucalypt woodland adjacent to rainforest. Sulphur-crested cockatoos nested in both habitats. Nest holes of…

Breeding biology of three large, sympatric rainforest parrots in New Guinea: Palm Cockatoo, Pesquet’s Parrot and Eclectus Parrot
Higher nest tree density, breeding success, and more generalised feeding habits may make Eclectus Parrots the least vulnerable of the three species.
Availability of nest hollows and breeding population size of eclectus parrots, Eclectus roratus, on Cape York Peninsula, Australia
This relatively low population estimate suggests that the Australian subspecies of eclectus parrots should be considered vulnerable to habitat loss or perturbation, especially in light of their complex social system, male-biased adult sex ratio, low breeding success and high variance in reproductive success among females.
Factors influencing nest-site occupancy and low reproductive output in the Critically Endangered Yellow-crested Cockatoo Cacatua sulphurea on Sumba, Indonesia
This study shows how low reproductive output can be in the critically endangered Yellow-crested Cockatoo Cacatua sulphurea and this has serious implications for survival of the population on Sumba.
Nest niche overlap among the endangered Vinaceous-breasted Parrot (Amazona vinacea) and sympatric cavity-using birds, mammals, and social insects in the subtropical Atlantic Forest, Argentina
The high level of overlap in realized nest niche, combined with previous evidence that cavities could limit bird density in the study area, suggest the possibility of interspecific competition for cavities among multiple taxa.
Competition and aggression for nest cavities between Striated Pardalotes and endangered Forty-spotted Pardalotes
Nest boxes are a promising option for restoring the availability of nest sites for Forty-spotted Pardalotes, but given the competition from Striated PardAlotes for nest sites, nest-box placement should take advantage of species differences in nest-site selection to minimize conflict.
The breeding biology of palm cockatoos ( Probosciger aterrimus ): a case of a slow life history
It is suggested that this slow life history makes palm cockatoos on Cape York Peninsula sensitive to environmental perturbations, with fire being the most probable threatening process.
Heterospecific competition in a threatened cavity-nesting parrot: a case study of the eastern Regent Parrot (Polytelis anthopeplus monarchoides)
ABSTRACT Nest cavities are a limited resource, given the extensive land clearance that has occurred in Australia. Some obligate cavity-nesting birds are vulnerable to extinction and experience risk
Breeding season of the Endangered White (Umbrella) Cockatoo, and possible competition for nest holes with Blyth’s (Papuan) Hornbill in North Maluku, Indonesia
The White Cockatoo Cacatua alba is endemic to the North Molucca islands and is considered Endangered mostly due to unsustainable levels of trapping for the pet trade. Little is known about its


The availability and dimensions of tree hollows that provide nest sites for Cockatoos (Psittaciformes) in Western Australia.
A 15-ha plot of salmon gum woodland contained 241 hollows with an entrance diameter and depth exceeding 90 mm, in 173 trees, the majority in salmon gums, and there was a trend for hollow size to decrease in the order: red-tailed black cockatoos, corellas, galahs and Port Lincoln parrots.
Nesting requirements of the yellow-tailed black-cockatoo, Calyptorhynchus funereus, in Eucalyptus regnans forest, and implications for forest management
The nesting requirements of the yellow-tailed black-cockatoo (Calyptorhynchus funereus) were studied at 68 sites in Eucalyptus regnans forest in the Strzelecki Ranges, South Gippsland, Victoria. Nest

The Availability of Tree Hollows for Use as Nest Sites by White-tailed Black Cockatoos
Data on nest hollows were collected from four study areas throughout the range of the short-billed form of the white-tailed black cockatoo, Calyptorhynchus baudinii latirostris, in south Western
Breeding biology of the reverse‐dichromatic, co‐operative parrot Eclectus roratus
The breeding biology and social system of the eclectus parrot Eclectus roratus, a species with a unique form of sexual dichromatism, was examined, showing that reproductive variance for females is high, and suggests that a shortage of tree hollows and eligible females may enforce co-operative breeding amongst males.
The evolution of nest-site selection among hole-nesting birds: the importance of nest predation and competition
Independent nest preference and utilization data suggest that all four species that vary their nest heights in relation to density prefer to nest high, and it is suggested that predation is the factor that has selected for this preference.
The Breeding Biology, Food, Social-Organization, Demography and Conservation of the Major Mitchell or Pink Cockatoo, Cacatua-Leadbeateri, on the Margin of the Western Australian Wheat-Belt
The breeding biology of the Major Mitchell or pink cockatoo, Cacatua leadbeateri, was studied over six years at Yandegin on the margin of the Western Australian wheatbelt, where the shrinking distribution in the face of expanding wheat farming is irreversible.

Breeding biology of crimson rosellas (Platycercus elegans) on Black Mountain, Australian Capital Territory
Poor environmental conditions for breeding were counterbalanced by decreased levels of conspecific interference through egg destruction, which suggests that female rosellas initiated incubation at different times during laying, and total hatching asynchrony increased over the breeding season.
