Anthropogenic noise is considered one of the most serious forms of pollution globally and has been shown to have negative effects on the distribution, behaviour, cognition and reproductive success of animal species worldwide. One of the most well researched impacts of anthropogenic noise is its effect on acoustic communication. Animals may adjust the rate, amplitude, duration, and/or frequency of their acoustic signals to better maintain communication when anthropogenic noise is present. In this study, we combine behavioural focals, amplitude measurements and audio recordings to investigate how female Western Australian magpies (Gymnorhina tibicen dorsalis) alter the acoustic features of their territorial song (known as a carol) when anthropogenic noise is present. Magpies reduced the rate at which they carolled when loud anthropogenic noise was present, and increased their peak frequency during anthropogenic noise, but, contrary to our hypotheses did not alter the amplitude, duration, or other frequency parameters of their carols. Results from this study add to the growing body of literature documenting changes to the vocal behaviour of wildlife in the presence of anthropogenic noise and highlights the importance of investigating multiple acoustic parameters to understand how species adjust their vocalisations in response to this pollutant.

Rising temperatures and anthropogenic noise are two of the most pervasive and well researched anthropogenic stressors affecting avian species globally. Despite often triggering similar behavioural responses in birds, and frequently co‐occurring (particularly in urban areas), the impact of these stressors are primarily investigated in isolation. Here, we discuss and compare the most commonly researched effects of anthropogenic noise and rising temperatures on avian behaviour. We then outline recent findings on the impacts of these two stressors on cognition in birds, which underpins many behavioural adjustments. We find that both anthropogenic noise and high temperatures, when investigated in isolation, impact avian behaviours such as foraging, the antipredator response, and interactions with conspecifics. We also find that both these stressors can lead to cognitive impairment, but the occurrence and magnitude of impairment varies depending on the cognitive trait examined. Finally, we discuss the limited studies that have investigated these two anthropogenic stressors simultaneously and outline different scenarios in which additive, synergistic, or antagonistic effects of these stressors may occur. We hope our review will stimulate researchers to investigate the simultaneous effects of these and other anthropogenic stressors on the behaviour and cognition of urban‐living wild birds.
