Key to maps

reddot.png(red dots) core records, known to represent existing locations of focal taxa; in the case of intra-continental migrants, only records approximating the taxon’s breeding distribution are used.

orangedot(orange dots) non-core records, representing vagrant occurrences of the focal taxon obviously outside its usual range, or historical observations of a taxon known to be extinct at that location.

greydot(grey dots) records of other subspecies of the same species as the focal taxon; or in the case of intra-continental migrants, non-breeding records of the focal taxon not included as core records.

blueploy(blue polygons) minimum convex polygons underlying the locational records on the maps that depict each existing taxon’s Extent of Occurrence (EOO).

yellowpoly

(yellow polygons) areas formerly occupied by Extinct taxa.

 

redarrow(red arrows) the location of taxa with very small distributionsand known seabird breeding locations.

Maps were made using the Geoscience Australia Lambert Conformal Conic (GALCC) projection.

IUCN Red List Status 2010  

Endangered A3cde+4cde

Environmental Protection and Biodiversity Conservation Act Status

Reason if Threatened or Near Threatened  

Ongoing population decline estimated greater than 50% over three generations (58 years) inferred from shooting by orchardists and loss of nest hollows to bees and other cockatoos

Reason if changed in 2000  

No change

Current Eligibility against IUCN Red List Criteria  

.

IUCN Category

Criteria Eligibility

A

Endangered - current and anticipated population declines 50-79% over 3 generations (58 years) suspected from contracting AOO, deteriorating habitat quality, levels of exploitation and effects of competitors

B

Not applicable - EOO greater than 20,000 km², AOO greater than 2,000 km²

C

Near Threatened - population near 10,000 mature individuals, suspected continuing decline, 100% population in 1 subpopulation

D

Not applicable - population greater than 1,000 mature individuals, greater than 5 locations

E

Not applicable - no population viability analysis undertaken
