Mechanisms of song production in the Australian magpie. [PDF]
J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2011 Australian magpies (Gymnorhina tibicen) are notable for their vocal prowess. We investigated the syringeal and respiratory dynamics of vocalization by two 6-month-old males, whose songs had a number of adult features. There was no strong lateral syringeal dominance and unilateral phonation was most often achieved by closing the syringeal valve on the ...

Sleep loss impairs cognitive performance and alters song output in Australian magpies. [PDF]
Sci Rep, 2022 AbstractSleep 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.

Heritability of cognitive performance in wild Western Australian magpies. [PDF]
R Soc Open SciIndividual differences in cognitive performance can have genetic, social and environmental components. Most research on the heritability of cognitive traits comes from humans or captive non-human animals, while less attention has been given to wild populations.

Preliminary evidence of tool use in an Australian magpie?
Behaviour, 2022 Abstract We investigated tool use in twelve wild-caught Australian magpies. When presented with a tool use apparatus consisting of two transparent walls with a food reward placed in-between, seven magpies pulled the stick out of the apparatus acquiring the food within.

Australian Magpies Gymnorhina tibicen cooperate to remove tracking devices
Australian Field Ornithology, 2022 Recent advances in tracking technology have enabled devices such as Global Positioning Systems (GPS) loggers to be used on a wide variety of birds. Although there are established ethical considerations to these processes, different species may react differently to particular devices and attachments. Thus, pilot studies are still of utmost importance in

Sex and Age Bias in Australian Magpies Struck by Aircraft
Birds, 2023 Wildlife–aircraft collisions represent a safety and financial challenge, necessitating site-specific hazard assessments, which are generally based on species’ attributes and collision frequencies. However, for many bird species, collision probability and risk may not be distributed equally among individuals, with sex and age differences possible but ...

Communal Breeding by the Australian Magpie-lark
Emu - Austral Ornithology, 1988 A recently favored hypothesis is that duetting in birds has a mate-guarding function: a male responds vocally to his partner’s song, thereby forming a duet that repels males who are attracted to her song. Previous studies have not provided unambiguous tests of the mate-guarding hypothesis because: (1) the probability of a male answering his partner’s ...

Angewandte Chemie, EarlyView.Precise modulation of Fe–N4 site distances constructs spin‐regulated Fe–N4 twins, triggering a volcano‐type Fenton‐like activity and promoting oriented singlet oxygen generation. The twin‐site catalyst enables highly selective and efficient hospital wastewater purification with simultaneous pharmaceutical degradation and disinfection under low ...

Australian magpies adjust their alarm calls according to predator distance
Bioacoustics, 2020 Many animals produce antipredator calls in response to the presence of a predator, which, in some species, can provide information about the distance to predator. Although previous research has shown that several bird species are able to encode information about predator distance in their calls, such information is still lacking for a range of species.
