Eucalyptus wandoo decline or a loss of canopy foliage can potentially alter foraging resources for woodland birds. In Dryandra State Forest and Wandoo Conservation Park, Western Australia, foraging activities of three bird species observed on E. wandoo trees of varying condition demonstrated that tree decline can alter the foraging resources for woodland birds.

The head is rarely targeted during agonistic interactions between hatchling Crocodylus johnstoni because they exhibit a unique ‘head raised high’ posture, and engage in ‘push downs’. The nature of agonistic interactions between C. johnstoni and C. porosus at 40–50 weeks of age suggests that dominance may be governed more strongly by size rather than species-specific aggressiveness.

We present nearly 300 records of the importation, sale, transportation and release of rabbits in the period 1788–1900, with more than 90 records before the popularly cited 1859 Barwon Park (Victoria) release. Evidence implicates native predators, particularly quolls, as responsible for the widespread and early failure of rabbits to establish on mainland Australia.
