Painting process of a #raven (Corvus frugilegus).

Long associated with bad luck in folklore, ravens are in fact impressively curious and intelligent birds. Some have even been observed using tools!

Silence will not shield scientists from the consequences of an increasingly hostile political landscape.

UK and other non-US scientists must act to support our US colleagues.

Here's what I think we should be doing...

Machine learning algorithms can predict emotional valence across ungulate vocalizations
Vocalizations can vary as a function of their context of production and provide an immediate measure of an animal's affective states. If vocal express…

🚨 New paper! 🚨
Using #XROMM on 15 #bird species, we show that trachea deforms with neck movements. This reshaping could impact sound frequencies, showing that #biomechanics of the entire vocal system is important to consider when studying birdsong 🐦🎶 #ornithology

Summary: Tracheal elongation in birds was found to vary between species and is not necessarily homogeneous; this significantly influences vocalization, providing new insights into the complexity of av...

Please enjoy this article on the origin of joking by Erica Cartmill, who studies the evolution of cognition and communication. Her observations of great apes clowning around are delightful, and she has fascinating ideas about why these behaviors evolved 🧪

Emotional contexts influence vocal individuality in ungulates
To group-living animals, such as most ungulates, being able to recognise the members of one's social groups is crucial. While vocalisations often carry cues to identity, they are also impacted by the ...

In recent years, the idea has flourished that plants emit and perceive sound and could even be capable of exchanging information through the acoustic channel. While research into plant bioacoustics i....
