Female song and vocal interactions with males in a Neotropical wren

Frontiers in Ecology and Evolution, 2015
Bird song is thought to function primarily in same-sex competition, mate attraction, and reproductive stimulation of a partner. However, these conclusions are based largely on studies of the song of male birds in north-temperate species.

Light‐Driven Quadrupedal Walking Biohybrid Robot With Antagonistic Muscle‐Rings and Inclined Joints

Advanced Robotics Research, EarlyView.
This work presents a light‐driven quadrupedal walking biohybrid robot powered by antagonistic muscle‐rings that achieve alternating walking gait. Optical training improved reproducibility of cultured muscle tissues, while caffeine treatment enhanced contractile force.

An attention bias test to assess anxiety states in laying hens [PDF]

PeerJ, 2019
Fear is a response to a known threat, anxiety is a response to a perceived threat. Both of these affective states can be detrimental to animal welfare in modern housing environments.

Context‐Dependent Reactive Antipredator Behavior of Chacma Baboons (Papio ursinus griseipes) Amidst Predator Recovery [PDF]

Am J Primatol
Chacma baboons exhibited context‐dependent flight and vigilance behavior in response to experimental predator vocalizations in Mozambique's Gorongosa National Park. Reactions were strongest in juveniles and in individuals with fewer otherbaboons in frame and in response to leopard and wild dog cues, and weakened with increased exposure to predators ...

Programmable Information Processing With Reconfigurable Self‐Contact Variable Stiffness Mechanical Metamaterial

Advanced Science, EarlyView.
Reconfigurable self‐contact variable stiffness metamaterials based on shape memory polymers enable programmable stiffness switching. Static arrays store and encrypt information with immunity to electromagnetic interference, while asymmetric stiffness converts symmetric vibration into directional matter transport.

Dance behaviour in cockatoos: Implications for cognitive processes and welfare.

PLoS ONE
Parrots (Aves, Psittaciformes) in captivity have been reported to show dance behaviour in response to music, which may involve complex cognitive processes including imitation, vocal learning and entrainment.

Food‐solicitation displays in nestling birds: still begging for answers

Biological Reviews, EarlyView.
ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.
