How to watch them Glossies are susceptible to disturbance, especially during breeding in January–September when it is critical not to disturb them. They eat the seeds of the drooping sheoak (Allocasuarina verticillata). A medium sized bushy tree that has a rounded head. Black Sheoak (Allocasuarina littoralis) and Forest Sheoak (A. torulosa) are important foods. Most habitat patches showed foraging signs, but most individual sheoak trees did not. Before the first white settlers began clearing trees and shrubs around Geelong, Drooping Sheoak, Allocasuarina verticillata was a widespread and distinctive feature of the Barrabool Hills and the Geelong region. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). Two potentially limiting factors, pollen and soil nutrients, were studied in the context of A. verticillata as foraging habitat for glossy black-cockatoos. ... Food source and habitat for birds.

The teeth (8–)9–13, are spreading, not overlapping and about 1 mm long. OUR HABITAT The Glossy Black-Cockatoo (KI) inhabits woodlands that are dominated by Drooping Sheoak and often interspersed with taller stands of Sugar Gum. The branchlets are up to 40 cm long, with internodes being from 10–40 mm long and 0.7–1.5 mm in diameter, broader at the end near teeth, and generally densely pubescent in the furrows, with ribs slightly rounded and a minutely roughened keel. The mid-storey may contain Native Apricot, Golden Wattle, Kangaroo-thorn, Sticky Hop Bush or Sweet Bursaria. These cockatoos form lifelong mating pairs and only feed on the seeds of drooping sheoak trees. Female flowers are designed to hang from the tree enabling them to catch the pollen.

SEASONAL DEVELOPMENT: Sheoak can flower and fruit year-round in warm climates [ 3 ]. The Glossy Black-cockatoo feeds almost exclusively on the cones and seeds of mature age Drooping She-oaks (Allocasuarina verticillata). The extreme dependence of the Glossy Black-Cockatoo (Kangaroo Island) on Drooping Sheoak for food makes this subspecies highly vulnerable to any process that might reduce the extent or availability of Drooping Sheoak dominated habitats. The valves are in several rows, sometimes extending well beyond cone body, broadly acute to acute, and often pointed. The minimum seed-bearing age is 4 to 5 years, and it produces a good seed crop annually. They eat the seeds of the drooping sheoak (Allocasuarina verticillata). Cone production was not limited by the amount of pollen available to female plants. Vegetation communities include areas of sugar gum (Eucalyptus cladocalyx) and drooping sheoak (Allocasuarina verticillata), as well as other mixed eucalypt woodlands.
