Species Wild Status

World Population:

7000-14,000

IUCN Red List Status:

Vulnerable

CITES Listing:

Appendix II

Threat Summary:

There has been a rapid population decline in the last three generations (35.7 years) that is likely to continue. The overall decline is estimated to be over 30% and is due to loss of forest habitat and increasingly severe bush fires. The 2019-2020 fire season likely exacerbated this. Climate change and resultant severe heat waves are projected to further affect populations.

Range:

C.l. lathami: E Australia from lat. 26S in SW Queensland south to E Victoria.
C.l. halmaturinus: Restricted to Kangaroo Island, S Australia. Formerly in Mount Lofty.
C.l. erebus: CE Queensland, in Dawson-Mackenzie-Isaac Rivers basin, and possibly west of Paluma Range in NE Queensland.

Habitat:

Found around Casuarina or Allocasuarina trees. Also prefers Eucalyptus woodland in high ranges. Occurs in riverine woodland, dense forest, semi-arid woods, coastal forest, wet and dry sclerophyll forest and brigalow scrub.

Wild Diet:

Specializes on Casuarina and Allocasuarina (A. verticillata, A. littoralis, A. torulosa), taking the cones from each. Also noted taking fruit, wood-boring grubs, sunflower Helianthus seeds, Acacia, Banksia and Eucalypt seeds.

Ecology and Behaviour:

Resident, but may move locally after breeding. Found in small, quiet groups of up to 20 birds but usually in smaller parties of 2 to 10. Often found in groups of two adults and one immature. Will congregate to feed. Not found in large flocks in open areas. Pair bond is strong.

Clutch and Egg Size:

1 ovate egg, 44.5 x 33.5mm (1.7 x 1.3 in).

Breeding Season:

March-August; nest is a bed of wood-chips in a tree hollow.
