Think chicken -- think intelligent, caring and complex

Research shows chickens possess complex cognitive abilities, including numerical understanding, self-awareness, and referential communication. They also experience emotions like fear, anticipation, and empathy, and demonstrate problem-solving skills in social situations.

'Mic check' for marine mammals

Researchers have developed a new passive acoustic monitoring method using autonomous underwater vehicles, gliders, and floats to capture sounds of marine life. The method, which was tested in the US Pacific, has the potential to provide more accurate data on marine mammal density and abundance.

Genes for speech may not be limited to humans

A recent study published in Frontiers in Behavioral Neuroscience has found that mice with a genetic mutation similar to the one affecting human speech also have difficulty producing complex vocal patterns. The study suggests that the FOXP2 gene regulates not only human speech but also mouse vocal communication.

Mobs are, sometimes, good

A Michigan State University study found that hyenas gain an advantage by cooperating during fights with lions, emerging victorious more often. The research team analyzed 27 years of data to fully describe this cooperative behavior, revealing that the number of participating hyenas increases their chances of success.

Mice sing like a jet-engine

Researchers discovered that mice create ultrasound by directing a small air jet against the inner wall of their larynx, producing an ultrasonic whistle. This innovative mechanism has implications for understanding social sounds in rodents and potentially even human speech disorders.

Genetic influence in juvenile songbird babblings

A study by Hokkaido University researchers found that juvenile songbirds exhibit familial differences in their earliest vocal babblings, suggesting a possible genetic basis for these variations. The findings reveal that the variations are more pronounced among different families and persist even when deafened.

What does the sperm whale say?

Researchers discovered that sperm whales use distinct tapping sounds to convey individual messages, similar to Morse code, allowing them to identify themselves and coordinate actions. The most communicative whale accounted for 294 of the recorded codas, sparking interest in learning more about its unique behavior.

New way to smell a rat means end for rodents

Scientists at Simon Fraser University have developed a new method to exterminate rats by replicating the male brown rat's sex pheromone. This attracts female brown rats, allowing for effective trapping. The discovery forms part of a three-pronged rat control tactic that also exploits sound communication and food preferences.

Study shows levels of panda hearing

A study published in Global Ecology and Conservation reveals that giant pandas can detect sound into the ultrasonic range, potentially disrupting their reproductive success due to noise from human activities. The San Diego Zoo's contribution to this research has provided crucial insights into panda hearing sensitivity.

Bird communication: Chirping with syntax

Researchers discovered Japanese great tits have developed syntactic rules, combining calls like 'ABC' and 'D' to convey specific meanings. These birds use these rules to deter predators and attract partners, demonstrating a complex form of communication.

The emerging science of human screams

Researchers found that human screams occupy a reserved chunk of the auditory spectrum and activate a range of acoustic information. Screams have a property called roughness, which refers to how fast a sound changes in loudness, making them more terrifying.

Male Java sparrows may 'drum' to their songs

Researchers found that male Java sparrows synchronize their bill-clicking sounds with the melody of their song, similar to human percussionists. This behavior suggests that birds may have an innate ability to produce and coordinate non-vocal sounds with vocalizations.

Mice sing like songbirds to woo mates

Researchers analyzed mouse songs using a new statistical tool, finding that males sing more complex songs when they smell a female's urine but don't see her. The songs' dynamics are influenced by social contexts and can be used to study vocal communication and disorders, including autism spectrum disorder.
