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.

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 ONEParrots (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.

Dynamic sex-specific responses to synthetic songs in a duetting suboscine passerine. [PDF]
PLoS ONE, 2018 Many bird species produce temporally coordinated duets and choruses, requiring the rapid integration of auditory perception and motor production. While males and females of some species are known to participate in these displays for sex-specific purposes,
