Vocalization is an important communication tool that can reflect many aspects of an individual's internal and external condition. This is especially true for birds. Previous research has shown that bird calls and songs change in response to a variety of potential stressors, although the extent and direction of the changes depend on the nature of th...
Sleep is one of the few truly ubiquitous animal behaviours, and though many animals spend enormous periods of time asleep, we have only begun to understand the consequences of sleep disturbances. In humans, sleep is crucial for effective communication. Birds are classic models for understanding the evolution and mechanisms of human language and spe...
Sleep maintains optimal brain functioning to facilitate behavioural flexibility while awake. Owing to a historical bias towards research on mammals, we know comparatively little about the role of sleep in facilitating the cognitive abilities of birds. We investigated how sleep deprivation over the full-night (12 h) or half-night (6 h) affects cogni...
Sleep is one of the few truly ubiquitous animal behaviours, and many animals spend vast periods of time asleep. However, we are only just beginning to understand the consequences of sleep disturbances on animal behaviour. While negative effects of lack of sleep on human speech are well documented, research on the influence of sleep disturbances on...
Performance in tests of various cognitive abilities has often been compared, both within and between species. In intraspecific comparisons, habitat effects on cognition has been a popular topic, frequently with an underlying assumption that urban animals should perform better than their rural conspecifics. In this study, we tested problem-solving a...

The dispersal of reproductive material plays a key role in the ecology of plants. Dung mosses (Splachnaceae), have evolved to utilise insects to disperse spores to habitat sites consisting of dung or dead animals—a marked departure from the wind based spore dispersal seen in other mosses. However, adapting to insect dispersal likely precludes long...
For a bird, it is often vital to visually detect food items, predators, or individuals from the same flock, i.e. moving stimuli of various shapes. Yet, behavioural tests of visual spatial acuity traditionally use stationary gratings as stimuli. We have behaviourally tested the ability of budgerigars (Melopsittacus undulatus) to detect a black circu...
