Vocal mimicry in Corvids. [PDF]
Anim CognAbstract Vocal mimicry, the copying of sounds produced by another species or the environment, is commonly described in vocal learners, such as songbirds. Understanding the functions of vocal mimicry can help to uncover the evolutionary drivers of vocal learning. Different adaptive functions like interspecific and intraspecific communication

Volitional control of vocalizations in corvid songbirds.
PLoS Biology, 2019 Songbirds are renowned for their acoustically elaborate songs. However, it is unclear whether songbirds can cognitively control their vocal output. Here, we show that crows, songbirds of the corvid family, can be trained to exert control over their ...

Drag reducing nose fairings for existing freight train locomotives
Advances in Aerodynamics, 2022 At cruising speed, one of the most significant contributing factors to train fuel consumption is aerodynamic drag, and the leading locomotive experiences much more drag than any other car in the train.

Task Aspects Triggering Observational Learning in Jackdaws (Corvus monedula) [PDF]
Animal Behavior and Cognition, 2020 Complex novel tasks are often used in animal cognition research to allow discrimination between various learning mechanisms. Successful performance relies on the capacity to identify informational cues from features in the environment.

The social life of corvids [PDF]
Current Biology, 2007 In large social groups with a linear dominance hierarchy, such as many corvid societies, the ability to make inferences about the relative status of individuals within this hierarchy is an important skill, often called transitive inference. For example, if Bob is more dominant than Joe, and Joe is more dominant than Simon, and Bob and Simon have a ...
